I'll check with my BIL. I think he did the race with his squad. I know he has completed a similar ride from somewhere near Logan Ut and finished at Jacksonhole Wyoming. So that will be a similar ride. I think he was a strong cat 2 rider at that time.

If nothing else, I'll get his ride report and will let you know. Yes do several 12-14 hour rides. And do maintain a 200mi/wk training. Minimum of 8 hour ride on each weekend. Have to get your body used to riding 80-100 mile ride every week!! I've completed several 100+ mile timed rides. At some point in your ride, you are going to feel like DNF'ing and can't ride anymore, so be prepared with the mental games. When that happens, you may not like it but drop your speed and recouperate physically and mentally. And conserve your energy on downhill and recover. Spin going downhill so your muscle doesn't cramp up. And do be careful on the winding road.
