I've been riding with my club's beginner group. Rode with the intermediate group last night. We were going so fast my HR monitor was showing my caslculated max HR, and they sped up. I just hung on . It sure made mew consider driving in today. The ride in was good for loosening up some seriously stiff legs. Ride home was nice. I'm working all weekend, so I'm keeping an eye out for drunk drivers. Ride safe.
