Wow, Boston was not what I was expecting at all this year. Seeing the high temperature from last year, was more thinking that it was going to be somewhat warm. And I love hot weather. Alas no. Here is a recap on my day and nutrition. (more…)

Ironman Mont Tremblant 2017 Part 2: It’s Go Time!


6 Comments

With all what went on in the Bay Area with the fires,  I didn’t feel super compelled about telling my Ironwoman story. Who wants to know about this, I’m no elite, not that young anymore either so who would care. But then I remembered that I always like to read blog about Ironman stories good or bad, it’s always a pleasure and a nice distraction. So here it is, your distraction for today. Warning though there will be some TMI moments, so beware!

How to Fuel an Ultramarathon the “Other” Way

Disclaimer: this was “only” 50k so it does qualify barely for an ultrarunning event as it is longer than a marathon. BUT it is also a very hilly course and had over 6000 ft of total ascension. It was absolutely beautiful with ocean views, forest runs and brutal descents. Here is a course overview.

It really took me a long time to write this post I know. I do not think that my story is particularly interesting or even worth sharing as an average middle age-grouper but sometimes I like to go a little bit more personal and share with the world my bigger accomplishments

I just remembered to write this post, when the other day I was watching a lecture on Nutrition for UltraRunning. As traditionally recommended*, the lecturer was suggesting 6-10g/kg day and during the race 90g/hr. She claims that your gut can get used to it and that will give you the best performances. She obviously has not heard of Zach Bitter, Tim Olsen, Nikki Kimball or myself (LOL!). Here is how I did it. (more…)

Metabolic Efficiency

What can you do for *ME and what can ME do for you?

This post was first published in the Run Experience in a slightly different version.

*Metabolic Efficiency is too long so let’s call it ME. Metabolic=metabolism and efficiency, well we know what it means. But the two together? How can your metabolism be efficient.

So here we go:

What is exactly Metabolic Efficiency?

First thing first, the Metabolic Efficiency concept was developed originally by Bob Sebohar, the renown Sport Dietitian. (Check out his website for the full story).

It is the capability of burning fat instead of carbs for the same intensity. You can train your body’s metabolism to use more fat at higher intensity exercise so that it results in glycogen sparing and be more efficient. Glycogen is the sugar reserve that you have in your body and is in limited quantity. Does it make more sense now?

How do you achieve that?

Training: The more trained you are, the most able you are to burn fat. In fact there was a recent study that showed just that. They took 9 pro athlete and 9 recreational athlete and compared for the same RPE their performance. They actually consumed the same amount of carbohydrates, the same amount of lactate was produced but guess what the pro athletes were much faster because they burned 3 times as much fat as their counterpart, so more energy generated from fats for same RPE. So they were faster for same RPE.

Gender: Women are usually better at burning fat. Yes, for once we have an advantage. Maybe it has something to do with us carrying babies and having to rely more on our reserve to grow life when food is restricted.

Exercise mode:  You burn more fat running than cycling because running is much more a whole body exercise, you recruit more muscle but at a lower intensity for each one. While cycling put a high demand on your legs muscle primarily. That is why you can get away with eating less during running compared to bicycling even when you burn much more energy.

Fasting: When you are fasting your body burns more fat because of lower insulin in your body. Insulin is known to shut down fat metabolism towards carb metabolism.

Age: As we get older we are better at burning fat. Yes really. Maybe that is why older athletes often shine in ultra endurance events.

20154357535_13068c9987_o

Day to day nutrition: And that is the big one. Do you boat load carbohydrates on a daily basis or do you fuel mostly on fat? If you fuel mostly on fat your body will adapt and burn more fat. Even if on race day you decide to carb load because you want to go long and fast (and carbohydrates are necessary to do that), this effect won’t just reverse, you will still burn more fat and be able to spare glycogen. This has tremendous consequences on health and performance.

How can you measure your metabolic efficiency?

You can go to lab and get hooked on a metabolic cart. It is a machine that measures the oxygen that you breathe and the carbon dioxide that you exhale. Using an algorithm, it can tell you how much fat and carbohydrate you are burning while on a treadmill or a cycle ergometer.

17817_10153169531179868_1568165122847603368_n

From there you can derive your caloric needs during training and racing at different paces. As you increase intensity, you will start burning more and more carbohydrates.

Here are two examples on the treadmill with two different athletes. Important to note that both of them report similar RPE for similar speed:

ME Figure 3

This athlete has a crossover point between 9 and 8.5 min/mile, meaning that they start burning more carbohydrates passed the 8.75 min/mile mark.

In this second example, this athlete has no crossover and is still burning more fat at 7.5 min/mile. Interestingly, this athlete burn mostly fat at rest. Do you think that she needs to eat carbohydrate when working at her desk?

ME Figure 1

Two totally different pictures. Let’s do a little math and take the 8min/mile mark.

First athlete:

695 kcal/hour

72% from carbs

500 kcal/hour or 125 g/hour of carbs

Approximately 30% comes from plasma glucose (from a classic paper by Luc van Loon et al. 2001)

87 g/carbs per hour

Assuming 300 glycogen reserve, that is 3.5 hours of fuel.

Second athlete:

695 kcal/hour

34% from carbs

208 kcal/hour or 52 g/hour of carbs

Approximately 30% comes from plasma glucose

36 g/carbs per hour

Assuming 300 glycogen reserve, that is 8.3 hours of fuel.

OK, I know, this might be an oversimplification.  One caveat of this calculation is that as duration increases your body will naturally start burning more fat. Also we have reserves of fat stored in our muscles, the more fat burning you have the more you store. These reserve also can get depleted which leaves you with your bodily reserves which, as you know are pretty unlimited even for the leanest athlete. How easily are those reserves accessed though? It can be more challenging.

Overall this is just to show you the advantage for endurance events. There are other advantages such as health, minimizing bonking, minimizing GI distress and also less acidosis because less lactate produced.

Does it work for everyone?

Most people report feeling great when they train their body to burn more fat: less sugar craving, less bonking, less eating during training and less GI distress. Does it work for everyone? Everyone is different and you might reach a point where lowering carbohydrates too much is too low (unless ketosis is what you are looking for).  Listen to your body! And remember that you still need some carbohydrates for long endurance event or even short and fast races, so timing is key! Consult with a good sports dietitian or nutritionist to know what works for you.

Hi! This is a long post and  I apologize. If you are only interested in the nutrition you can skip my jabbering and go directly to the relevant paragraphs. That is fine with me!

When I started triathlon 10 years ago, I never wanted, never thought I would do an Ironman. Its too crazy, too much, too hard, not good for your health. So then why did I decide to do one? Just that: it’s been 10 years and I had to try one, no choice. Plus my kids were getting bigger and I had quit my job, so no more excuses. Because let’s not underestimate this Ironman, it is a lot of training!

The Training:

In order to be successful I hired a coach, JD. It was so valuable I cannot say the least. He really kept me healthy during the whole process. The training was hard for sure. I had to remember to eat well (of course) and sleep a lot (more challenging).

The bicycling part was the most difficult for me as it takes the longest.  So far in my life,  I had done lots of 60-70 miles bike rides and also lots of bicycling tours but never above the 80 miles mark in one day.  I had a lot of work to do, or so I thought. But JD had me do only four rides that were 80, 90, 100 and 90 miles.  That’s it.

The running came in a little bit more easily because I’ve always been a runner first.  However the longest run I did was only 19 miles with lots of hills which would prove to be much more difficult than the flattish marathon at the end of the IM.

Swimming felt fine, as I had done over the distance several times.

Even with all that, I was not feeling too confident that I would be successful because how can you run a marathon after 112 miles of cycling and 3800 yards of swimming?  However I trusted my coach as he said I was ready so I tried not to worry too much.

The Tapering:

The Ironman was up in Whistler and we decided to drive there in 2 days. I actually thought that driving was a great idea especially if you have someone driving for you. What better than doing nothing for 8 hours with feet elevated on the dashboard. I had been feeling pretty tired but after that drive up and minimal training apart for the treadmill in the hotel gym, I was starting to feel back in the groove of things.

As soon as we got there we went for a swim to Alta lake, where it was going to start. The lake was beautiful and the temperature was perfect (70F). I had brought a sleeveless wetsuit just in case but I did not think I would need it at that point because the weather forecast said it was going to rain. The swim in the lake was great and freshwater is always so nice to swim in, except for the leeches…My husband told me that the swimmer that had gotten out just before me had one stuck to his leg. Nice. And then my son tells me: Mom you have a leech on your ankle! I jumped and looked down, it was only a leaf. Gosh. What can you do if you have a leech stuck to you during the race? That’s enough to drain your blood by the end of it.. I did try not to think about it, anyway it’s always better than being bitten by a shark.

The next day I went for a short bike ride. By then my legs were really feeling fresh! What a difference as I had been training on tired legs a lot.  The road were also wide and well paved. I was finally getting excited.

On the Saturday I did a quick swim and run and started preparing all my transition, special needs bags and nutrition needs. Wow, it’s like planning a wedding. I had a list of all the things to do, where to put them. Then I had to go drop my bicycle at the lake via the shuttles with all my bags except for the nutrition.  I was getting a little nervous then. Fortunately I saw my friend Erika in the shuttle bus so that gave me a break from my thinking brain. I spent the rest of the afternoon prepping nutrition and relaxing. We went out for a good dinner. I did not stuff myself, had chicken veggies and potatoes, very safe. Oh and some dessert too that we shared amongst everybody. And a non-alcoholic beer, because I like the taste.

Race Day!

I had set my alarm at 4:00AM, was planning to get on the first bus at 5AM ish. The start was at 7AM but I preferred that since I did not know what to expect. Of course I was awake by 3:00 and could not sleep anymore. Been there, done that so I know that one night of bad sleep would not impact me that much. I got up and made a super strong Bulletproof coffee. I don’t drink coffee regularly so when I drink one, it’s party time. Just that was making my day already (see earlier post). For those of you who don’t know what a bulletproof coffee is, it is coffee with butter and MCT oil (medium chain triglyceride), it is a type of fat that gets readily absorbed and metabolized pretty quickly, and in your brain too. It is derived from coconut oil. With that on board I started to get ready, I also prepared my pre-race smoothie which I would start drinking an hour before the race start. It contained some almond milk, cliff organic food pouch: banana, mango and coconut, some peanut butter, 2 scoops of plain UCAN superstarch and a little whey protein and that is about it!  Nothing to weighty.

The Swim!

One of the thing I felt ready for was the swim. But I forgot about the MASS START. The coach told me don’t go in the middle and of course this is where I was. I thought I was in the front, but no. I could see Erika, she was right there at the front, she is a fast swimmer and I thought I should be fine where I was. NOT. It was terrible. I could not swim freely for the whole first lap and I had to constantly find holes and ways to not get kicked. It is only after the first lap that I started feeling that I had more space. But even though just to be safe I stayed pretty far from the buoy. As a result my total distance was 4600 yard and normally it is 3800 yards. Rookie mistake number 1! I don’t know how accurate these Garmins are. My watch said that my pace was 1:34, which would have been a little fast. But overall it took me 1:12, I was a bit bummed but the swim is such a small portion that I did not let it get to me too much.

By the time I was out of the water, it was raining hard! I went to get my bag and then remembered about the wet suit strippers. Where were they? Found them got that taken care of and went in the changing tent. That is one nice thing I must say about Ironman, is the changing tent with all the volunteers that help you get dressed. I had decided to change completely and since it was raining I was hesitating on what to wear: wind breaker or no windbreaker: no windbreaker because I was feeling warm (bad decision). Fortunately I stashed it in my pocket just in case. 12 minutes transition! mmm, need to work on that one. Rookie mistake # 2

The Bike!

It was raining hard on the bike. I thought, it is going to be a long day of wetness, first moment of darkness but swooshed that thought away. I was hoping that the forecast was going to clear a little bit later like the weather forecast was saying. On the first 10 miles, I got cold very quickly and was shivering. I hope I don’t get hypothermia, I thought. Pedal faster to warm-up, I said to myself. And so I did, but it did not work that well. Remember that wind breaker? That is when I stopped and put it on. Even though I was all wet under, it still warmed me up. I could see the pros coming back from the first turn around on the other side and some of them were actually quitting already because of the bad weather…Well that does not look good. However I managed to warm up. The only thing is that my wind breaker is not really aerodynamic and was acting more like a parachute. Not good. Rookie mistake # 3.

When I got to the special needs I was happy to have dry socks there. I finally removed my windbreaker because the temperature was raising and it was no longer raining. Then the boring part started: dead flat for 30 miles. Ugh. That was hard for me. I don’t have a TimeTrial bike and my position is not optimal and it was not comfortable. Which made me thought that after this I need to get a real Time Trial bike or quit triathlon because this sucks. That was my dark moment number 2 but I managed to pushed it away and focused in the moment. That meant thinking that I had to go pee badly and was not going to pee on the bike. Really people? Who does that? Mind you I was already wet.  The sad part is that at every aid station there was a long line at the porta-potty. Fortunately I eventually found one which was at the other side of the road and was free!

Then I saw Claire and Erika coming back on the other side and that motivated me to keep the pace. Finally we got to the hills. Yeah! You must think I’m crazy but I was so happy to get out of aero position just sit really straight and push up and up. I was feeling really good at that point, knowing that the bike was going to end soon and that after an uphill, there is a downhill. My legs were getting tired but not too bad. Seven hours and I was done, better than anticipated with those hills!

Me and my parachute.
Me and my parachute.

Bike Nutrition

At least I got the nutrition right!

I got my first dose of UCAN approximately 1:45 hours into the race. I had in it some MCT oil (2tsp) and BCAA (3g) to complement and I would have that every 1:45 or so. I also was eating quarters of BonkBreakers every half hours if no UCAN and alternating with some peanut butter and honey. I really felt good with even energy.

The Run!

I was really happy to finish the bike and get into the run. Was trying not to think that I had to run a marathon until Claire reminded me as we were finishing the bike together (thanks Claire, shut up Claire, you are still my friend though!)

Again, I got in the changing tent for a complete wardrobe turnover! Applied bunch of anti-chaffing everywhere and was ready to go. The volunteer was so encouraging and she told me she was going to be at the finish to tell everybody it was my first one. How nice!

I started running with Claire and saw my family on the side cheering me on. So nice to see them. In my head I did the calculation: 20 aid stations divided by 4 equals 5. I can still do math! OK, let’s focus on the first 5 ones, first one quarter. I would run like that pretty much the whole time: run to #1 as fast as you can, walk, have a sip, eat maybe and then repeat and start over for the next 4. That got me busy. Walking at each aid station also breaks it up and helped avoiding cramping and injury and really it does not change your time that much if you walk for 10 seconds. My pace was pretty even for the whole race but did slow down a little bit as time went on. Oh and no I did not see any bears. 4:26 marathon, pretty far from an open one but I’ll take it!

Going on the run
Going on the run

Run Nutrition

About 30 minutes in I had a dose of UCAN again, with some EAA in it that is it. I also sipped on a Peanut Butter GU gel for an hour . No too much fat not to upset my stomach and anyway I did not feel hungry at all at that point and had good energy. Of course my legs were tired but I guess it is normal. I was only drinking water to thirst at aid station and having salt pills for what it is worth, research is not clear on this one yet! At the special needs I was feeling really thirsty fortunately I had put a Perrier can in my bag and gulped half of it which totally quenched my thirst. I don’t know what it is,  but the combination of bubbles and slight sodium is just wonderful.  At that point I was suppose to take another dose of UCAN but instead I opted to start coking it up. I never drink Coke but this is when I do it because there is always a place for sugar and caffeine! I also started having broth as it was getting cold when it started pouring again.

The Finish!

Hurray, the finish line! I was getting so pumped up and started picking up the pace, I still had it in me. But the villain course designer had us do a zig and a zag in the village before heading to the finish. When is that going to end? Nevertheless, I was so happy and smiling at everyone. I saw my family at the end and high fived everybody at the finish line. This is as close as I’m going to feel like a super star, red carpet and all but definitely not looking too glamorous.

High-Five!
High-Five!

Nutrition Summary

3x27g UCAN orange flavor: 330 kcal,  81g of carbs

1×1.5 scoop plain UCAN: 135 kcal, 33g of carbs

4 tsp BCAA, 2.5 g/tsp

6 tsp MCT oil: 200 kcal

4 Tsp peanut butter: 400 kcal, 28g of carbs

8 tsp honey: 160 kcal, 40 g carbs

1.75 Bonk Breakers: 473 kcal, 58g of carbs

1 GU gel: 90 kcal, 22g of carbs.

app 0.75 can, not too sure about that one: 120 kcal, 30g of carbs

also some salt pills and caffeine pills.

Total: 1908  kcal, 145 kcal/hour and 292g/carbs and 22 g/hour. This is actually pretty good for me and even on the high side as at those pace I am more of a fat burner but since it was my first IM and I did not experience any GI issues at all, why not?

According to my Training Peak files and Metabolic Efficiency data, this is what I burned during the race: 287g of carbs during the bike, 150 g of carbs during the run and let’s say 30g during the swim. 467 g total. Bout 70% comes from glycogen reserve or the equivalent of 300 g. That is pretty close to what I would have stored in my legs. Of course, this is just an approximation and it is important to remember as the duration increases your body start burning more fat, so I probably burned less than that. I still have a lot of work to do if I want to go faster. But what counts at the end is that:

I am an IronWOman!

Finish!
Finish!

I really want to thank everybody who supported me. My husband, my children, my coach(es) and all my friends. I was really touched and surprised by all the support I got on in the form of messages and phone calls. Thank you!

Eat This! Not That!

This post first appeared on the Run Experience in a slighter shorter, modified version. Have fun trying new things!

If you are like me, one of the first thing I do before a race is check out where the porta potties are along the course. Just in case. Or if you are like my friend, you are packing on the Imodium before also just in case. Most often I do not have to deal with such issues but the idea of eating food as your stomach shuts down.  Here are some ideas on how to tweak your diet before, during and after races so to minimize GI issues and be healthier.

Before the Race

Instead of a big bowl of pasta the night before a race try a couple of sweet potatoes.

Carbohydrate loading before races as long been the practice of endurance athlete. For 2-3 days before the race we were told to eat boat loads of pasta, bread and the likes. This practice can bring its own problems such as bloating, water retention and even GI issues during the race. It has been shown that this practice is not necessary. Especially if the week before an event you are taking it easier and eat a healthy diet. The day before an event you can increase your carbohydrate ingestion a tad bit. Some suggestions would be to include the day before a bowl of rice, sweet potatoes or just plain potatoes. If these don’t fancy you try something sweeter like a bowl of ice cream but don’t overdo it.

Instead of a big bowl of oatmeal 3 hours before a race sip on a smoothie  90 minutes before.

Why would you want to lose precious sleep and get up 3-4 hours before the start of a race to ingest an enormous amount of oatmeal? I remember doing that before my first marathon, If you have done things correctly, you glycogen tank should be full from the day before. If you are getting up early anyway because you need to travel, have a light snack, such as a banana or a sport bar. Now to tank up your system before the start, sip on your own smoothie made with the following ingredient, mix and match as you like. The smoothie will keep you hydrated and empty from your stomach pretty rapidly. Start sipping on it 90 to 75 minutes before your race.

Mix and match smoothie:

1 cup almond milk
1/2 cup frozen fruit you like (blueberries, mangoes, banana)
1/2 cup plain Greek yogurt or a third of a scoop protein powder
1/4 cup uncooked old-fashioned oats or you can also substitute with a slow release carbohydrate powder such as UCAN or Carbopro
1 tablespoon chia seeds or even a nut butter of your choice.With 30-40g carbohydrate and 10g protein, you are good to go.

During the Race:

Instead of Gatorade try a drink with electrolytes only.

Gatorade is very popular among athlete and the reason is clear, it has the right amount of electrolytes and carbohydrates to keep you going. Nowadays the recommendation is to drink to thirst during racing or training so that you don’t overdrink as hyponatremia could ensue. The problem with using Gatorade is that anytime you drink you also ingest carbohydrates which could lead to GI issue. A better practice is to separate your electrolyte fluids from your cabohydrate consumption (see next paragraph for recommendations. Use an electrolyte powder in your water such as Nuun or Base Salt or bring electrolyte pills with you if you plan to drink water instead at aid station. (Salt Stick). Salt intake is very individual and for shorter races we probably do not need to take any, however it is not a bad practice to prevent hyponatremia.

Instead of gels try nibbling on real food.

Gels are a quick fix to maintain your blood sugar level during a race. But it can also bring you on the sugar roller coaster. You feel good for 15 minutes than sugar levels go down and you reach for the next gel resulting in gel overdose. You know that feeling in your stomach that too much stickiness is in there. Another alternative would be to nibble on real food every 15 to 30 minutes instead whether it is a sport bar, your own nibble or a food pouch such as these from clif bar or munkpack. Make sure that you don’t ingest more than 10g of carbohydrate at a time to get your blood sugar in control. Look at the label to give you an idea of how much you should eat at a time. If that seems to complicated, you can also use a slow release starch as mentioned above and sip on a dose every 60 to 90 minutes. Again for races shorter than 75 minutes you won’t need to take anything in really.

After the Race:

 

Instead of chocolate milk try your own recovery drink.

Chocolate milk has a good reputation these days thanks to marketing wizards and studies that the milk industry sponsored that shows that milk is excellent for recovery. And it is, it has a good amount of proteins, carbohydrates, electrolytes and antioxidants from the chocolate. However most of the carbohydrate comes from the sugar added. Try your own recovery drink instead, similar to the pre-race smoothie just add some extra protein by using milk instead of almond milk or add up to 1 cup of greek yogurt or up to one scoop of your favorite protein powder. Drink within 2 hours of completing your event earlier if you are doing back to back hard effort (crazy you).

Instead of a beer try a non-alcoholic beer:

There has been a lot of press about beer as a recovery food. It is definitely not bad at all because it contains carbohydrate, electrolytes and vitamins. However, it is the alcohol that hurts and can blunt adaptation signals in your muscles.  Also too much alcohol could act as a diuretic and impairs re-hydration. Try a non-alcoholic beer instead and add a bratwurst with it for some protein. I know it is not the same thing but now you know…

Instead of fast-food burgers try fast-food burgers.

No this is not a typo. Recently there was a study that looked at the effect of fast food on recovery. The reality is that if you analyze a fast food burger on a macronutrient level (fat, carbs, protein) it is not bad at all. However at the micronutrient (vitamins, mineerals, antioxidants) level it might not be the best and it would not be advised to do this everyday but if you are traveling and that is what is available, go for it!

One last note, it is never recommended to try something new during a race so practice before during training and see how your stomach feels with those recommendations.

Are You High on Caffeine?


7 Comments
End of January 2015, are you still on track for your new years resolution? For some it might be losing 5 pounds or stop drinking, for me it is to quit caffeine and write my first blog ever on caffeine effect. I’m still on track to post my first blog ever but did I totally quit caffeine? Not really and here is why.
Photo Jan 15, 2 55 09 PM
Maybe you don’t know it but caffeine is highly addictive for certain people. And that applies to me. Caffeine is everywhere. Apart from the obvious, coffee, it can also be found in colas, energy drink and a lot of sports bars and gels.  A cup of coffee can have up to 200mg caffeine, Gu gels vary from 20mg to 40 mg, one of my favorite Pocket Fuel Cold Brewed Coffee Gel has 70mg and Clif shots have a more decent potency with their double espresso at 100 mg. Caffeine can also be hidden in the form of other ingredients such as yerba mate, kola nut, green tea extract, just to name a few.
Caffeine is a plant alkaloid similar to what is in cocaine, nicotine, morphine. All of these being classified as stimulant. The difference is that it is legal, like nicotine. Why? It does create a dependance but it is not life threatening, it can however be life disturbing when you don’t have your cup of joe in the morning. For me, if I did not have access to coffee for a couple of days that would mean seriously bad migraine.
So what makes caffeine so special. A couple of things you might be interested to know without getting too much into the rocket science. First and foremost caffeine stimulates catecholamines. What it means is that it releases adrenaline, noradrenaline and dopamine, and also indirectly cortisol. This hormonal mix creates the fight or flight response and it is believed that this is why it decreases RPE or perceived effort. It also lowers the threshold for muscle excitation. Adrenaline stimulates lipolysis and glycogen utilization, your whole body metabolism gets primed. It is not surprising to see caffeine in most weight loss supplements, as it also decreases appetite through the mechanisms I just mentioned. Most studies show very favorable effect for caffeine. It reduces the time trials in endurance sports in general and increases time to exhaustion during strength training. Who would have known that something so ubiquitous would have such nice effect? Yet I feel it is pretty underutilized.
But studies do vary in their results. And it has something to do with the subjects and how naive were they to caffeine. Because the more used to coffee you are, the less effective it is, you get a blunted output of cathecolamines. Therefore most studies use 24-48 hours with no caffeine or even up to 4 days to desensitize subject. It probably works, but it might not be enough for certain people and it is also probably why such high doses of caffeine are needed, that is 4-6 mg/kg, 30 to 60 minutes before exercise or 200 to 300mg of caffeine for me. For some people it can take up to a month to get rid of the habituation and then caffeine can only be used once or twice a week to really see the benefits.
Another important point is that most of these studies use a placebo but between you and me it is pretty hard not to know that you just had the equivalent of 2 cups of coffee. And as I will explain in another post the placebo effect is a really strong one. If I convince you that caffeine works and have a cup of coffee before your ride, you WILL go faster. Crazy.
So why did I decide to quit caffeine? So I could try it as an ergogenic during training and racing and really know if it was working. It took me a month to get off it. For some people going cold turkey might work but it did not for me, for the reason I mentioned earlier. I gradually decreased my amount to finally go caffeine free coffee. I really like the taste of coffee and it is some sort of ritual so I still have it in the morning in the decaffeinated form. I use this decaf bean from Bulletproof. They claim that they use a mycotoxin free bean and they use the Swiss water process to take out caffeine, which is a chemical free process compared to decaf you can get at Starbuck and the likes. It is more expensive though…
So now here I am caffeine free! And I feel like I’m in rehab, some days it is hard. But being caffeine free made me realize how sleep deprived I was. Also, I realized how caffeine was making me nervous and gave me the jitters. Now I have a large cup of coffee usually on Saturday morning before my big ride of the week, it is probably at about 150 to 200mg. Sometimes I do the Bulletproof thing, which is no longer a secret as Runner’s world and The New York Times published articles on this. It consist of coffee, a tablespoon of butter and MCT oil. Good stuff. After that I feel like superwomen. 6:30AM Saturday morning and I am ready, I start jabbering so much that my husband asks me what is wrong with me, I feel euphoric, I am hot and sweaty (literally). Hop on the bike and I hammer those pedals. Zone 3 feels like zone 2, my watts are up the roof, it is working. After 2 hours, I feel a little bit of a slump, I go for another dose (Pocket Fuel Cold Brewed Coffee Gel, 70 mg). I’m a junky. I crank up the music in my ear buds and smile for the rest of the ride. Is the effect real? Is it placebo? Maybe a little bit of both
