OPSF 50/50 Trail Race

The OPSF 50/50 Trail Race is a popular running event held in Owen-Putnam State Forest, Indiana, organized by the Indiana Trail Running Association. Participants can choose from various distances, including a 50-mile race, a 50K, a 14-mile run, and a 10K trail race. The course features predominantly single-track trails with rolling hills, making it one of Indiana's toughest trail races.

The event emphasizes sustainability by being a cup-less race, requiring runners to carry their own water. Registrants receive a shirt and are eligible for age group awards and finisher medals. Early registration is encouraged due to limited capacity. Visit the organization's website for the most recent information.
