Knobstone 50, Borden IN

The Knobstone 50 is a rugged, point to point 50 mile trail race that follows the Knobstone Trail from Deam Lake State Recreation Area to Delaney Creek Park. The course accumulates roughly 10,000 ft of elevation gain and traverses rocky ridges, dense hardwood forest, narrow single track, exposed ridgelines with sweeping views, shaded valleys, and multiple creek crossings.

Runners must check in and out at every aid station; aid stations cannot be skipped, including New Chapel, Elk Creek, and Spurgeon. The event provides well stocked aid stations, live GPS tracking, professional photography, pre and post race meals, a free shuttle to the start area, and a cupless format where runners carry their own refillable container.

Crew access and pacer rules are specified. Crews may meet runners at Leota (25.6), Elk Creek (32.8), Oxley (38.2), and Spurgeon (44.4). Pacers are allowed at Elk Creek, Oxley, and Spurgeon only and must register, complete a waiver, enter or exit at designated aid stations, and wear a pacer bib while on course.

Runners may use up to five on course drop bags plus one finish bag at designated aid stations; bags should be small, clearly labeled, and must not contain perishable items, glass, or coolers. The finish celebration includes a handcrafted finisher award assembled in pieces earned at specific checkpoints and a communal Finisher Slab listing finishers.
