DESCRIPTION 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 : 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 won’t 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 fin
