KROP - Kaizen Rite of Passage

KROP takes place at Welling Ridge Trails just outside Tahlequah, Oklahoma. The event uses a single 4 mile loop that serves as the course for all distances, bringing runners back through the start and finish area each lap. Each loop has approximately 417 feet of elevation gain and loss on rock covered, root twisted single track.

Distances offered:

  • 4 mile
  • 8 mile
  • 25k
  • 50k
  • 65k
  • Ruck relay teams

Notable features include a randomly appearing bonus mile and the Kaizen ROCK of Passage challenge. The rock challenge is restricted to entrants 18 years and older and may require carrying a rock of 60 pounds or more on technical single track. The ruck relay is team based with a maximum of four people per team and teams compete for total loops within a timed period.

Finishers who complete one 4 mile loop receive an award. 50k and 65k finishers receive a special belt buckle. Top three finishers on each distance receive gold, silver, or bronze versions of the finisher medal. The event provides on course aid, hot food available mid morning, breakfast items, and event hospitality. The event is chip timed and photography is provided. Donations given with registration are donated in full to the Tahlequah Trails Association.

The event proceeds rain or shine. In life threatening weather it may be moved to a virtual format or deferred for a later year. Volunteer roles include setup, packet pickup, course marshalling, aid station support, and pack out. Registration includes a shirt; shirts are guaranteed for registrations by 2026-08-28. Each parent entry includes one free child entry for children age 15 or under at live events. Visit the organization's website for the most recent information.
