Hey all. I've just started riding again after not doing much for a few years. I used to ride 100 miles a week, and had lost a substantial bit of weight. Now, I've gained the weight back (I'm at 265) and lost my base fitness. Anyway, I've been starting off slow doing 10 mile rides. Yesterday, at about mile 6, I lost all energy, had a hard time pedaling, and even thought I was going to have to get off and lay down for awhile. It was a bit scary as one of my legs started to shake while I was coasting. I had water and was drinking, but I didn't eat anything before I left, (this was right after work). Today's ride was much better with no problems. I guess a snack is important before you go.
