The Holliday Park Trail Run includes fun events for the whole family Friday evening, and both a 5-mile run and 3-mile hike on Saturday morning. Participants will scramble, run, jump, ford, climb or walk along the trails of Holliday Park to Marott Woods Nature Preserve and back again. Participants will be challenged by hills, stairs, ravines, swales and gulleys along the White River and Williams Creek.
