Organiser's Description
DESCRIPTION
KROP: KAIZEN RITE OF PASSAGE YEAR 2: DON'T CALL IT A COMEBACK!
Guess whos 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 lapwhere 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: Our friends at Lake Vian Hilltop Run have inspired this part of our course! At a random time during the day, a bonus mile will appear! It wont count toward your mileage, but it will count towards your fun! There will be some keepsakes and fun sights along the way should you dare take this extra mile challenge.
THE KAIZEN ROCK OF PASSAGE: A massive stone that appears at random. Whomever brings this ROCK back to the finish line will receive a crisp $100 bill as a reward. Year 1 there was only one stone. Year 2 we guarantee at least TWO stones that will 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 OR MORE 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 youll earn a finishers 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 beltseach sponsored by a different local business.
THE VIBE:
This isnt just a raceits a 12-hour trail running party fueled by Team Kaizen hospitality:
Donuts for breakfast starting at 6am
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 brutalrock-covered, root-twisted single track that demands focus every step of the way. You may trip. You may fall. But if you dont show up, youll 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 18:00 PER MILE.
Special note about the 65k: Have you heard of the Pumpkin Holler Hunnerd? It's a 100 mile race that's also hosted in Tahlequah, OK but in the month of October. The first loop of Pumpkin Holler is 40 miles and the pace to finish all 100 miles is...you guessed it...18 min/mile. We intentionally set up our 40 miler to be YOUR PERFECT final training run should you take on Pumpkin Holler in October!
Whether this is your very first trail race or your next ultra, KROP promises challenge, camaraderie, and celebration for every runner.
