I took a trip to Lancaster Pa. this weekend. I was riding along and spoted a rider ahead of me so I caught up to him. Having never riden the area and going along with just the aid of a map I ask if he knew where the covered bridges were. He said sure so off we went. Although the climbs were not that long some were rather steep. I was keeping up but gasping on the steeper hills. I guess I need to concentrate on aerobic training if I'm going to ride in hills.
