Announcing Our Summer Training Run Schedule!
Runs are open to all runners, entered in the race or not. Please study the maps, bring turn by turn directions, and be prepared to navigate and care for yourself on the trails. The course will be minimally marked and some routes have water stops, but all runners need to carry adequate water and nutrition for the entire distance of the run.
