Well, when people asked me about my strength in triathlon, I always answered “My ability to eat.” It might also be significant that I’m a Borer, but I don’t know. All I can say is that I practiced my nutrition plan, was comfortable with it, and it worked for me on race day. This type of sophistication for 12+ hour finishes is amazing. I heard of Sabatschuss (8h finisher) that he did his best IM on cola only because he forgot or lost some of the foods he was planning to eat. I heard of many pros not having much of a strategy, just take the gel theyre sponsor provides some water some energy drink and make up the plan on the way.
What good is a nutrition plan if you throw up? I have no idea, but I will do my first IM next year without that much of a plan, just take some gels and bars with me and eat them whenever possible. The race makes my plan, what good is a beeper that goes of when I am in a 12% climb or on a 50mph downhill? I did a half ironman this year – with a plan – this plan was worth nothing after i put the bike on the side for a pee break and lost all my energy dring stored in the aero bottle. After half of the bike portion all the energydrinks were given away and I had to do with water and the one bar that I brought with me as a backup. Was a great race though and I finished one hour faster than my plan. Um, it reminds you you’re supposed to eat, so you do at the next convenient time?
I don’t think anyone is advocating slamming on the brakes so you can eat your gel just because your alarm went off. Of course, if you plan well enough, you’ll make sure your alarm is only set to go off when your on the flat or a gentle slope. I use Hammer gel, endurolytes, & plain water. I set the “countdown” timer on my watch, & every 25 minutes I swallow a serving of gel. Depending on how hot it is, I’ll typically 6 to 10 endurolyte tablets. I build up stomach acid pretty easily, so I typically use the “plain”, unflavored hammer gel. Also, I might stash some Tums or Rolaids in the bike & run special needs bags. It works well for me,
