As an ultrarunner, I’m all too familiar with the saying that long-distance running is an “eating contest with a running component.” I constantly experiment with gels, gummies, drink mixes, and bars, trying to figure out how to get the calories and carbs I need to get through hundreds of miles. Being able to take in fuel is easily the biggest factor that can make or break a race. Over the past 10 years, I think I’ve gotten things pretty dialed in.
