Glad to hear I am not alone? My first day out last Thursday, I quit at 1:00PM. I was feeling very tired and I just wasn't linking my turns together. Plus, my herniated disc was acting up. The next two days, I woke up, hardly able to straighten up.
I was thinking I should just go back to skiing. Instead, I'm going to dust off the bike trainer and work my legs while I watch TV.
Maybe I can't just drink beer and play golf all summer and expect to be in riding shape.
