Training objective: recovery ride with high cadence of 85-95. Took a while for the group to get going - we had several stops within the first 600 meters with heavy traffic, then a flat tire just as we got out of town which seemed to take a while (32 minute mark?), then someone's crank shaft came loose (50 minute mark?). Finally, we got going - I kept the cadence high, but by this point the group was eager to put the hammer down after all the stopping and starting. So, I kept up with the boys in the front, but kept the cadence high. We did have a few sprints where my heart rate got up there, but I was focusing on the high cadence and not worrying about heart rate on this ride. I had to give the guys a break and take the lead a couple of times, but I never felt like I was really pushing it.
