Boy did I make a rookie mistake Thursday. My pastor and I did a 18 mile ride beside the river here in east Tennessee. He on his Trek roadbike and me on my Schwinn mountain/road bike. BTW, I was supposed to pick my new 2.3 Trek the same day, but it didn't arrive at the bike shop. Anyway, I had a horrible time staying up with him. We rode before and I stayed with him mile for mile, the problem was this: when we got back to my truck to load my bike, I rubbed up against my back tire and it didn't move an inch. To make a long story short, I rode 18 friggin miles with my back brakes on. I feel like an idiot. I did aweful that day, cramping for the first time since I have been riding. I rode 25 miles today and did fine after fixing the problem. Being new to riding I now realize I should have stopped and checked it out. I was trying to hard to keep up instead of riding my own pace where I could have noticed. Just wanted to share that with someone, it's actually pretty funny now, but Thursday it was killing me. lol lol lol Still waiting on my 2.3, maybe Monday.
