Whew, just got back from a 5 mile bike ride. My brother came with me, he was welcome company although some of his riding scared me, too much riding in the middle of the road! We went about 1.2 miles on our street, then turned and went 2.5 miles on a dirt road, then got back on our road and came home. The whole thing is hills, it starts on a long hill up (almost all the way to the dirt road) and my muscles were screaming!! After yesterday I really felt like they were going to just stiffen up. Somehow they got less sore and I made it the whole way without getting off my bike. It was great!
