Heather,
I have never mountain biked - but I have ran for 13 hours...so I usually combined simple and complex sugar with little protein and fat. I have PRed on Lara Bars, Almond M&Ms, a little cantelope, V8 (880 mg of sodium), Endurolytes (All of the electrolytes), and Hammer gels (as backups). They are my staple race foods. I suppose you need to run and eat at the same time...so try stuff training and see how it works. You don't want to take a lot of fructose in because it causes stomach distress and brings water into the stomach. If you are reading labels of gels, look for maltodexrin. It is absorbed faster than a complex carb (vegable, brown rice), but slower than glucose (honey). Hammer Gels and Gu are gluten free, as are lara bars, and Almond M&Ms. The sodium and calcium in V8 are good - remember that with out electrolytes your brain can not function. They are also needed for muscle contraction. You should shoot for 200-250kcal an hour. I usually average about 220 on long races. In short races, like marathon length, I just stick with 4-5 gels and water. Good luck....Lisa

I'm doing a 24 mountain bike race in a couple weeks, and am wondering what the best thing is to eat (between laps and also before/during the race). It's a relay race so I'll probably only be doing 2 or 3 laps (about 18 km each). We're camping at the site, so there's not going to be anywhere to cook/heat up food.
Any tips on what I should do for food??
Thanks for any help,
Heather
