12 Hour Endurance Event

The Outdoor X12 Endurance Run and Ruck takes place in Dayton, Ohio, as part of the Subaru Outdoor Experience. This event is held in collaboration with Five Rivers Metroparks. Participants have 12 hours to traverse a loop course to earn a finisher medal. The event features two distinct categories for participants: a standard endurance run and a ruck division.

Course Layout

The route consists of a loop measuring approximately 2.7 miles. The terrain is comprised of 4% paved bike path and 96% grass and trail double track. The course is characterized as being flat throughout the entire loop.

Event Categories

Participants can choose between two primary event types:
