On March 8 at 0930, Fort Sill is hosting a 17-mile bike race through the middle of one of the ranges. They won't be firing that day. I registered last night on Bikereg.com. It looks like a citizen race from the registration. I called and they have a 55+ age group, which will be my first race in that category. It is a great course, rolling with several long and short 4-6% climbs and one 40+mph descent. I rode the course on the one-speed today and am hoping to borrow a bike with gears from the post chaplain tomorrow--he's an avid rider.
