Rockin K Trail Runs : Kanopolis State Park

The Rockin K Trail Runs are a multi-distance trail event held at Kanopolis State Park near Ellsworth, KS. Distances offered include:

  • 50K Trail Run
  • Trail Marathon
  • 21 Mile
  • 4 Mile

The course is four interconnected loops: Horsethief Canyon Trail, Prairie Trail, Alum Creek Trail, and Big Bluff. The Rockin K loop is the marathon route; 21 mile entrants skip the Big Bluff loop. 50K runners complete the Big Bluff loop twice. The 4 mile course runs from the Corral shelter to Horsethief Canyon and back.

Course markings use pink ribbons outward to the manned Gate 6 aid station and orange ribbons on the return to the finish. About ten large welded gates are on each loop; some must be opened and closed by participants. Several fence crossings have blankets over barbed wire and there are locations marked with caution tape.

At least two manned aid stations are planned with additional unmanned water points weather permitting. A camping style toilet will be at Gate 6 and porta potties and park restrooms are available at the start and finish. Crews may access Gate 6 by parking on the road and walking approximately 1/2 mile; vehicle access is limited and may require high clearance in wet conditions. Pacers are not allowed.

Entries are limited to 120 combined. Registration closes March 28, 2026. The event policy states no refunds; race deferral or partial carryover credits are possible if requested by specified dates. Packet pickup and other race logistics are handled at the Corral shelter. Visit the organization's website for the most recent information.
