Every month at our camp there are campers and instructors preparing for races.  The subject for many of the training conversations surround how to fuel.  Read the article below from the New York Times' Gina Kolata on the science behind fueling -  or not - during endurance events.  After reading, tell me what or if you've been fueling and if this article changed anything.

Workouts May Not Be the Best Time for a Snack

By Gina Kolata

A few weeks ago, a friend showed up for a run with a CamelBak — one of those humplike backpacks with a tube that allows you to sip liquid — and a belt containing food to eat along the way. Every 20 minutes or so as we ran, he stopped to eat and drink, sprinting afterward to catch up.

Now that is unusual, I thought. Does it really help to eat so often during a 16-mile run?

Certainly a lot of athletes believe they need constant nourishment. My friend and running partner Jen Davis, who has entered more races and run more than I ever have, once went on a 30-mile training run with a guy wearing a CamelBak and bearing snacks. He stopped every 20 minutes along the way and then, about halfway through the run, pulled out a turkey sandwich.

“I’m not sure if he ever actually ran an ultra race,” Jen said. “He may have gotten injured after carrying that heavy pack on those long runs.”

There is no end to the crazy foods people will eat at endurance events. At the J.F.K. 50-Mile in Maryland, boiled potatoes and chicken broth are provided at aid stations. At the Rocky Raccoon Endurance Trail Run in Texas, runners can choose rice and beans or pasta, along with snacks like pretzels, cookies and candy.

At a 100-mile bike ride my husband and I have done several times, pumpkin pie is offered about 25 miles from the finish line. (My husband tried it one year and felt ill the rest of the ride.)

For the athlete determined to munch on the go, there are shelves worth of prepackaged “energy gels” and bars, even jelly beans, promising to raise performance.

But most athletes are not running 30 or 50 or 100 miles, nor are they doing the equivalent amount of exercise in another sport, like cycling or swimming or skiing. So most of us really do not need to keep eating during a race to maintain energy and stamina, said Nancy Rodriguez, a sports nutritionist at the University of Connecticut.  Continue reading on NYTimes.com
