Mountain Biking: Refuleing in 24hr. Bike Race

Next weekend I am riding as part of a team in the 24hr Of Great Glen Mountain Bike Race.  I have never competed in a 24hr. race before.  I am looking for eating suggestions for in between laps the will not be heavy but give me the energy my body will need.  I plan to use gels while riding my laps as needed.  I hate to feel full while riding so I tend to under eat and sometimes bonk.  This won't cut it in this type of race.

 All suggestions or comments are appreciated.

Thanks!

First, you need to do in the race what you've been doing in training.  However, most people experience little GI distress on the bike because of the way the body is positioned and working.  (Obviously, if you're going all out, you'll have more issues).  In an endurance event of this nature, you should be keeping your heart rate down, so not an issue.

 You might find that your body can take a whole lot more food than you're giving it.  Prior to runs, I would never consider eating much of anything.   I'll eat some fairly serious food prior to bike rides.  I also consume much more on the bike than I ever would touch when running.  On foot, I eat perhaps 150 calories/hour (gels and fluids).  On the bike, I'll take as much as 350/hour.
