As I start out doing long-distance/endurance type riding I've been experimenting with different types of nutrition. My longest rides so far have been 100 miles. I have tried running solely on liquid nutrition, (after a solid carb heavy breakfast) and have had good luck so far, but again only 100 miles. Is any one aware of any studies on doing long distance rides solely on liquid type nutrition, have any of the RAAM riders done this?
The liquid nutrition I have tried so far have been, Optimum whey protein powder mixed in water, ensure, sport type drinks, liquid gels.
Those of you who are more experienced, any thoughts, advice?
