Knobstone 50

Event

The Knobstone 50 is a rugged, point-to-point trail race in Borden, Indiana. The distance is 50 Mile. Registration opens on Wed. Oct 1, 2025. The event is staged by Trailblazer Running and uses the Knobstone Trail, described by the organizer as steep and hilly and reminiscent of the Appalachian Mountains.

Course and logistics

The course runs northward from Deam Lake State Recreation Area (1217 Deam Lake Rd, Borden, IN 47106) to Delaney Creek Park (8215 Delaney Park Rd, Scottsburg, IN 47170) and accumulates roughly 10,000 ft of elevation gain. A shuttle transports participants from Delaney Creek Park to Deam Lake. The race includes proactive cut-offs at aid stations: Elk Creek (32.8 mi), Oxley (38.2 mi), Spurgeon (44.1 mi), and a final cut-off at the finish (50.0 mi) with an overall time limit of 19 hours.

Awards and policies

All participants receive a custom performance hat made from 100% recycled materials. Each finisher’s name is etched onto a yearly Finisher Slab. Podium awards are given to the top three male and top three female finishers; there will be no additional awarding in the non-binary category at this time. The organizer accepts entrants’ declared gender as Male, Female, or Non-Binary and provides an option to record preferred pronouns. Participants who become pregnant after registering or who are the parent of a recent newborn or adopted child may defer their entry for up to two years; the race may require proof and asks that runners contact the Race Director in advance to process a deferral.
