Race Info
Park2Park is an annual half marathon and 5K held the fourth Saturday of September in Holland, Michigan, starting and finishing at the Ottawa County Fairgrounds. The USATF-certified half marathon course runs along the shore of Lake Macatawa through Waukazoo Woods to Holland State Park, then loops north to Tunnel Park before returning to the fairgrounds. The race is the largest annual fundraiser for Neighbors Plus, a Holland-based community development organization.
