Just wondering if there are ways of estimating what I should be drinking and eating on rides. I am assuming a lot of this is dependent on things like age and weight. Just trying to figure out what I should be doing. I am basically a B rider but would not have a problem doing a B+ plus pace. If I could get my weight down about 10 lbs I could do even better. Not really bad for having just turned 67. But, when I have problems on rides that are 50+ miles it's all about the fueling.

Today we did a 42 mi. ride that had a couple serious climbs and by the end I was getting close to spasm in my legs. I'm pretty sure I didn't drink or eat enough but on the bike I often feel like I don't want to drink. Don't know why exactly.
