Knobstone 50

The Knobstone 50 is a point to point trail ultramarathon held in southern Indiana along the Knobstone Trail. The course travels northward from Deam Lake State Recreation Area in Borden, IN to Delaney Creek Park in Scottsburg, IN and covers a 50 mile distance with roughly 10,000 feet of cumulative elevation gain.

The trail is described as steep and hilly and is often called "The Little AT" because parts of the route resemble Appalachian terrain. The route passes through backcountry sections with steep climbs, forested landscapes, and scenic vistas. The event uses shuttle service between Delaney Creek Park and Deam Lake for participant transport.

The race includes proactive cut offs at aid stations and an overall time limit. Entrants may register as Male, Female, or Non Binary and the organizer accepts each entrant's declared gender; there is an option to provide desired pronouns during registration. Each finisher may have their name etched onto a ceremonial Finisher Slab. The top three male and top three female finishers at the distance receive podium awards; at this time there is no additional awarding in the non binary category.

Registration opens October 1, 2026. Optional commemorative performance hats made from recycled materials are available as an add on during registration. The event is produced by Trailblazer Running. Visit the organization's website for the most recent information.
