Yea, I'm sure could have riden the 23 without needing anything if I had prepared.
I was running around all day looking for a new seat post clamp since I snapped the bolt in my original from over tightening, then the LBS gave me the wrong size and I had to go back.
I didn't really eat today. I had a slice of pizza for breakfast(I'm from Jersey) then I had a cliff bar for lunch that I grabbed at the LBS cause I was starving.
I'm sure if I ate a real meal I would have been fine.
Yesterday was really hot and sunny and I rode a little before I broke the seat clamp, then ran 4 miles and after that I played full court basketball till it got dark and I was fine, just thirsty and didn't really eat much all day. The heat makes me just not feel like eating a lot.
I think I'll make some pasta/tuna salad early tomorrow to have to get some fuel in and maybe a pb&j sandwich and I'll take the cliff bar with me.
