I'm doing an Ironman in about 4 weeks. Having just completed a half Ironman a couple of days ago, I'm feeling upbeat after performing well. However, I have a question about nutrition for my forthcoming race. For my half Ironman, I ate mostly protein the night before, porridge in the morning, then structured my gels throughout the race accordingly;
- One half an hour before the swim I ate a gel, and sipped at a bottle of Hi5 upto the race start
- Once on the bike drank two further bottles of Hi5 and four gels during my 50 odd miles
- On the run I drank several small plastic cups of water/Hi5 from the aid stations, and a gel at miles 6
I use thicker un-caffienated gels, as the ones with a thinner viscosity ones are repulsive. I've heard from friends and have read that some people put gels (up to 26!) into a bike bottle, and consume this during the ride. However, this needs to be done with caution as it can adversely affect your constitution! Is gel choice a personal choice, as in what agrees with you, or should I avoid specific types?
I do have Ankylosing Spondalytis so I'm also worried about the hot weather, and my genetic inclination towards hyponatremia.
