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 loop that returns to the start/finish area each lap. The loop is single track, rock covered and root twisted, with approximately 417 feet of elevation gain and loss per loop.
Distances offered include:

Event features include a random Extra Magic Mile that does not count toward official mileage, and a Kaizen ROCK of Passage challenge in which adults 18 and older may carry a heavy stone found on course for a cash reward. A single 4 mile loop earns a finisher award. Special belt buckles are awarded to 50k and 65k finishers. Top three finishers in each distance receive medal variants. Ruck relay teams compete for full sized championship belts over the event period.
