Event Description
DESCRIPTION
KROP: Kaizen Rite of Passage – Year 2
Guess who’s back!? KROP returns to Tahlequah, Oklahoma at the rugged and scenic Welling Ridge Trails for its second year!
Runners can choose from 4, 8, 16 (25k), 32 (50k) miles, or the brand-new 40 mile (65k) distance. All races follow the same 4-mile loop, bringing you back through the start/finish area every lap—where the energy, food, and support never stop.
And because this is KROP, you can expect surprises along the way:
The Extra Magic Mile: At a random time during the day, a bonus mile will appear! It won’t count toward your mileage, but you’ll find plenty of fun (and maybe a few wild sights) along the way.
The Kaizen ROCK of Passage: A massive stone that appears at random. If you’re bold enough to carry it all the way to the finish, you’ll earn a special prize.
Finisher Perks & Awards:
Complete just one 4-mile loop and you’ll earn a finisher’s award.
50k and 65k finishers take home a special KROP belt buckle.
Top 3 finishers in every distance will receive gold, silver, or bronze variants of the finisher medal.
In the Ruck Team Relay, teams battle for 10 hours straight, piling up miles for a chance to claim full-sized championship belts—each sponsored by a different local business.
The Vibe:
This isn’t just a race—it’s a 12-hour trail running party fueled by Team Kaizen hospitality:
Donuts for breakfast
Burgers & dogs on the grill starting at 10am
A fully stocked aid station with the salty, sugary fuel every runner craves
The Course:
Welling Ridge Trails are beautiful but brutal—rock-covered, root-twisted single track that demands focus every step of the way. You may trip. You may fall. But if you don’t show up, you’ll definitely miss out.
Whether this is your very first trail race or your next ultra, KROP promises challenge, camaraderie, and celebration for every runner.
Are you ready for your Rite of Passage?
Race Day Highlights:
Early breakfast and then HOT FOOD all day long starting at 10am!

DONATIONS
Any additional donations given upon registration will go directly to the Tahlequah Trails Association. Please help us give back to them for their generosity and hard work. 100% of the money donated will go to TTA to help them with future maintenance and projects. These are good people. Let's help them out.
COURSE
The race course at Welling Ridge Trails is a 4-mile loop that starts and finishes at the start/finish area. All race distances will follow this same loop, which is a relatively flat, single-track trail offering beautiful views of the surrounding landscape. With approximately 417 feet of elevation gain and loss per loop, this course offers a perfect challenge for runners of all levels.
Remember, it's suppose to be hard. And you can absolutely finish it.

Bad Weather
There will be no refunds. It's Oklahoma, so you can't predict the weather, that's why at Kaizen we say every day has the same weather. This event happens rain or shine. In case of life threatening weather conditions the event may be changed to virtual or deferral to the following year.
Pack a poncho, cowboy.
Volunteers
