The McKirdy Micro Races are designed to provide every participating athlete with a full elite experience to maximize their chances of achieving their goals. This includes personal bottles every 4 miles, dialed-in pacers for steady goal-pace support, and a spectator-friendly course allowing frequent viewing opportunities. The course is designed to be the shortest path to your goal, marked with a tangent line to ensure exactly 26.2 miles are run. It is USATF certified and eligible as a Boston qualifier.
Every finisher earns a medal, and all runners who finish under 4 hours will receive a limited edition finisher shirt from Lousy Running.
