Other Details

Please note these are VERY tough courses, much tougher than the previous Ray Miller races. No exaggeration. Not at all recommended for a first 50-mile. All three race courses are extremely difficult. Absolutely no pacers allowed. Thank you.

This will be a cupless race. No plastic! We will not have cups at the aid stations. You must be self sufficient and carry hydration.
