The 1-mile is an out-and-back. The 5K goes on paved bike paths along the Tuolumne River. Flat and fast, this one is great for a PR (personal record). Awards three deep in 10-year age groups in the 1-miler, three deep in 5-year age groups in the 5K. Prize money to top three men and women in the 5K as well as top master (over 40) in each gender.
