Did my second Tuesday night hammer ride tonight with the local club, and got introduced to a new form of cycling torture: yellow diamond sprints. I expect many of you are familiar with these, but they were new to me. On a group ride, when you come over a hill or around a bend and spot one of those traffic signs shaped like a yellow diamond off in the distance, that instantly becomes the finish line for a race to be contested by the front three or four riders in the group. And off you go! Boy, you want to find a way to get your heart rate going, that'll do it. The group I ride with ranges from college students to serious geezers, with no obvious correlation between speed and age. I just loved seeing a bunch of 50+ (and 60+) riders sprinting for a road sign like their lives depended on it. Made me feel like I was about twelve years old again ("Race ya to the stop sign!!!").
