Spring On The Trails Endurance Runs

We are excited to be back for year three of our first Spring On The Trails Endurance Runs. This event will be a timed 3-Hour, 6-Hour, and a 12-Hour race on a 5k trail loop with about 250ft gain each lap. Cover as many loops as you can in the designated time whether your going for the shorter or longer race options. No matter the distance you cover, you will be coming out for a great trail racing experience.
