I have recently taken up bike riding as a way to stay fit. I dusted off my old Trek 4100 trail bike last month and put it to good use. I changed the tires to ones more suitable for the road, then started riding early weekday mornings (as schedules permit) and occasionally on the weekends. I also decided that I wanted to try a "group ride", where hundreds of cyclists get together and go on a long ride. My original plan was to ride 30 miles in the group ride, but I ended up doing 50 miles! Here is the story.
