Eating on the bike is more than about making sure you’ve got enough fuel – a good enough reason for figuring out how to eat efficiently on the bike but also to help maintain mental acuity.  I found this great article on Eating on the Bike.  It s a bit long but is jammed pack with great information and suggestions. 

Eating on the Bike.

I’m continually amazed at the things I see cyclists eat during and after rides but am never surprised to see the effects ranging from loss of energy, through loss of concentration leading to

mistakes and sometimes injury, to a full-fledged bonk.  The basic roles played by glycogen storage, blood glucose and the extraction of glucose from ingested carbohydrates are well understood as is what you need to do to avoid nutrition-based problems while you’re riding.  That doesn’t stop riders from falling prey to these problems all of the time, however.  Sometimes cyclist’s ideas about nutrition are based more on currently popular nutritional fads than sound knowledge.  Sometimes riders have an emotional commitment to eating particular foods and don’t want to change.  And sometimes you know what to do but you just can’t bring yourself to do it.  Whatever the reason, ignoring basic endurance nutrition almost always means trouble.
