KROP - Kaizen Rite of Passage

KROP is a loop-based trail event at Welling Ridge Trails near Tahlequah, Oklahoma. All distances follow the same roughly 4 mile single-track loop that begins and ends at the start/finish area, bringing participants back to the central aid and support area each lap. The loop is rock-covered and root-twisted single track with roughly 417 feet of elevation gain per loop.

Distances offered:

• 4 miles: one loop, approx 417 ft elevation gain
• 8 miles: two loops, approx 834 ft elevation gain
• 16 miles (25k): four loops, approx 1,668 ft elevation gain
• 32 miles (50k): eight loops, approx 3,336 ft elevation gain
• 40 miles (65k): ten loops, approx 4,170 ft elevation gain
• Ruck relay teams: up to four-person teams, each team uses one bib baton

Finisher awards and policies include a finisher award for completing one 4 mile loop, special belt buckles for 50k and 65k finishers, and top three medals for each distance. The ruck relay uses a 20 lb ruck or vest for the active runner, only completed full 4 mile loops count, and exchanges must occur in the start/finish area. There is a strict event cutoff and no drop downs for ultra distances.

The event features a bonus "Extra Magic Mile" that appears at random and a voluntary Kaizen Rock challenge for ages 18 and over that may require carrying a heavy stone on technical trail. Registration includes a shirt; entries completed by 08/01/26 are guaranteed a shirt. Early packet pick-up and race day packet pick-up are available; packets must be collected at least 15 minutes before the posted start time. Additional donations at registration go directly to the Tahlequah Trails Association for maintenance and projects. Volunteer roles include setup, packet pickup, course marshaling, aid station, and pack out. Visit the organization's website for the most recent information.
