Fueling During A Marathon
-
Like (0)
Hello,
I'm looking for some guidance from experienced long distance endurance athletes on fueling during a long race.
I just ran the San Diego Rock and Roll Marathon and was very disappointed that I missed my PR because my hamstrings cramped with only .6 left! I was feeling great the whole race, on pace to break 3:10, and with that short distance to go I could not run off the cramp and had to walk/hobble to the finish line.
I sweat a lot so I use a lot of fuel, but the fact that I'm still cramping late in these races tells me that I still have some adjustments to make.
Here is what I typically take in during a marathon:
I carry a 20 ounce bottle filled with Hammer Perpetuem (270 calories plus many other electrolytes)
2-3 Hammer Endurloyte pills per hour as suggested on the bottle
6 E Gels (Made by cranksports.com. I choose them because they pack more calories, sodium, and potassium than anyone else I've researched)
Water at every aide station to either refill my bottle or just drink out of the cup.
I've tried the "less is more" idea as well and still cramped around mile 22.
Whatever suggestions you have would be greatly appreciated. Thank you in advance,
Joey

Try honey packets (natural, unrefined and easily converted to energy) or Honey Stinger if you prefer the gels. Also, by-pass some of the aid stations because you really do not know what you are getting, so preparing your own fuel belt is a less risky. Look at your overall diet (increase your iron intake maybe) and the combination of things that you are currently using..something may be interferring with your digestive system and performance. (So, the pills, the gels, the Hammer, and the unknown water sources may not all be mixing well, for example).
You mentioned trying the less is best idea, but try the honey instead of gels and then eliminate either the Hammer pills or drink to see if that makes a difference.
Wishing you all the best.
Might be more with your training, sounds like you should have had plenty?
I get dehydrated absurdly quickly as a result of a few experiences with heat exhaustion in the military. As a result, I've had to get a laser focus on my sports nutrition strategies. I have a strategy for hydration and one for calorie replacement. For hydration, I stick with the stuff focusing on hydration: Gatorade/Nuun/all the hydration tabs from various manufacturers (Gu, Hammer, etc). For calorie replacement, I focus on stuff promising just calorie replacement (Clif Shot is a good one for that). That way you lessen the variables you're messing with which allows you to know where to make tweaks.
What's your diet like outside of your training nutrition?

Sorry I haven't responded... I was not ignoring your responses. I have taken all of them into consideration and have been trying new things during training.
To answer your question usnavy233, I eat a very healthy diet with a splurge if I'm going out to eat with friends. Here is a typical day for me:
Breakfast: Plain oatmeal with raisins and blueberries mixed in and a banana on the side.
* If I'm doing a long training session or a long race I will also have a piece of toast with peanut butter.
Lunch: Turkey sandwich on whole grain bread with avocado, tomato, cucumber, romaine lettuce, and mustard. Also carrots and a granola bar of some sort.
Dinner: Lean meat such as chicken, fish or chicken/turkey sausage, whole grain pasta or rice, and mixed vegetables.
* Red meat proably once a week.
I also snack every hour or 2 with an orange, apple, bagel with peanut butter or nutella, yogurt or greek yogurt, trail mix, clif bar, peanut butter and jelly sandwich...
I drink lots of water all day with a sports drink, usually diluted, at some point during the day as well.

OK,
Based on your regular diet I would say you're getting plenty of nutrition pre-run. It almost seems to me that you're overdoing it with 6 E-gels (I'm a fan of cranksports to) plus Endurloyte every hour plus Perpetuem off the start. That just seems like a lot more potassium and sodium than your body can use. I could be wrong on that, but that's just my first impression. But for now...
What's was your training plan leading up the marathon? How many miles per week, what was your long runs and how many did you get in, etc? Maybe the culprit isn't nutrition overload.

I know it's more than what my other racing friends take in, but "less is more" didn't work too well for me either. I don't think being undertrained is the issue...
Training:
Run: 4 runs per week consisting of 8-10 mile tempo, 10 miles in the hills, 4 mile recovery, and then a 16-22 mile long would get me between 40-50 miles a week. I get 3 20+ milers in before race day.
Swim: 8000-10000 meters in the pool IM drills, build drills, and short and long distance sets.
Bike: 60-100 miles per week depending on work.
Lift: 2-3 times per week. Full body, medium weight and high reps, lots of core, cross fit mentality with little rest time.
Taper: Reduced workout intensity 2 weeks before the race.

A few general comments.
- You don't say what your training paces are.
- More miles, less cross-training. I would think more like 60 - 70 mpw.
- Inadequate taper. 3 week taper, decrease volume substantially across the 3 weeks (70%/50%/30%), and minimize, if not eliminate the cross-training.
