Thanks for the information. I have a friend in the August race and it sounds like he has a practice ride coming up next Sunday morning.
Well, the practice run was last Sunday. Stephen did it in 1 hour 25 minutes 30 seconds. When you watch the video he was not pushing at all. Did not even seem winded at the end. He was working on learning the course and figuring the gearing adjustments to be made. Amazing to watch the video.
