Looigi - I sort of agree, but the reference is at least two, probably more like 3-4 years out of date by this time and it doesn't focus on the older athlete and potential health problems.

TromboneAl - Yeah, sure, four years ago I could have done a ride like that standing on my head (and I don't mean that in a World Cup goalie sense, but, I digress…) and now I'm totally not the same person WRT endurance sports. Trust me - don't screw around with nutrition, it can really come back to bite you in the ass. Instead of posting about how little you can get by on, please post tips on how to maintain a healthy diet, including in ride fueling, for aging endurance athletes. You're a really good athlete - don't abuse your gift. It can disappear all too soon.
