Endurance enthusiasts may be interested in checking out www.sfthorserace.com/theracehtm. They are applying for AERC sanction. Reading the logistics is mind boggling! We helped with the National Championships at Fort Valley, Virginia a few weeks ago. Anytime I need proof that I will be able to ride into at least my 70's, I will volunteer at an endurance event. There were plenty of folks who were not "spring chickens" competing in and completing the 100 miler!
