There's a trail I ride frequently in my area. There are usually a few cyclists, but primarily there are people on foot (and a lot of elderly people some days). One section of the trail has a KOM score with speed of 36+ mph. I can't even begin to fathom riding 36mph on this section of the trail, there is a bridge that is wooden and fairly narrow, and I wouldn't want to imagine an accident with pedestrians that would occur at these speeds. The crazy part is that it is listed as a climb, with 10.9% grade ... the speed that people get on this climb really make me realize how low level of a rider I am (although I guess being on page 2 out of 9 isn't the worst) ... thanks Strava :/
