KROP: Kaizen Rite of Passage – Year 2: DON'T CALL IT A COMEBACK!
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.
Why it's called a rite of passage: so you've done a 5k? Wanna go further but a 10k is too much? We've got a 4 miler for you. So you've done a 10k but a half marathon is too much? Ok, we've got an 8 miler for you. Need something to bridge the gap from half marathon but not quite marathon distance? We got you, try out our 25k. Have you already conquered the marathon and want to take your first step into the ultra world? We've got a 50k. And for those of you who have done a 50k and want to start working your way towards a 50 miler or maybe even a 100k...we now have a 40 miler! The directors of KROP are passionate RUCKERS and KROP is an outstanding place to slap on your first weight vest and move as a team with friends! Scratch all that...maybe you have never set foot on a trail before...we would love for KROP to be your very first trail run ever. And one final layer, maybe you're an experienced trail and ultra athlete, we believe KROP is a fantastic place to PR! Achieve your fastest 50k or
otherwise!
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. And yeah...if you're curious it will be a DIFFERENT extra magic from year 1 and it will absolutely be a solid extra mile.
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. Year 1 there was only one stone. Year 2 we guarantee at least THREE stones that will all be hidden on the course and available for the challenge. This challenge is NOT easy and is for entrants 18 years of age or over only. Let us be clear, we are asking you to potentially carry a 60lbs rock with you on single track, technical, root twisted trails. It's as brutal as it sounds.
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 including everyone's favorite BLUE GATORADE that ain't watered down.
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.
The Pace: To complete our 50k you'll need to maintain a pace of 22:30 per mile. To complete our 65k you'll need to maintain a pace of 22:30 per mile.
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?

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
