This was a great event! I was impressed that they added more and different obstacles compared to last year. We had a crew of 5 this year-1 more than last year. We had a lot of fun and we are all expecting to come back next year! Plus, the team checking us in was fun and helpful, the crew on the course was friendly and concerned, I pulled a muscle on the last rope climb and the guy came over to make sure that I was OK. Great group at Highlander, thank you!

Can’t Miss OCR

Highlander Assault is constantly upping its game and trying out new obstacles. This local race is something that seasoned obstacle course racers shouldn’t miss and one that is great for first timers!

Well organized and the friendliest people around. Multiple distance options and competition levels that match your experience. Good times! Highly recommend.

FANTASTIC EVENT! Upgraded again over last year! More trails, new obstacles! This event just keeps getting better and better. Have you heard of Tilt-a-Kilt?? You’re missing out if you don’t sign up for this one. Multiple distances make this a go for everyone- 4 miles to 26.2. I’ll be back again next year for the night race and for King Arthur. This race embodies the heart of OCR - fun, supportive, teamwork, challenging. And hello…..bagpipes ❤️

Great event

Well organized. Planned out nicely. The course was in great shape. The obstacles were challenging but doable. My only complaints are that there should have been done Gatorade or other sports drink on the course. Water stations were not mashed by anyone, they were self serve when I finished the monster hydro was already gone.

The best!!

I think I've done 4-5 Highlander races now and each time it's been a great race in a fantastic atmosphere! Excellent challenging obstacles through an amazing terrain. Those producing the race and those participating make it a thoroughly enjoyable event every time!

This by far one of my faves that my girlfriend and I take the 8 or so hour drive from KC to attend it. We speak so highly of it that we hope that more of our KCOCR friends will be jointing us next year! So if you haven’t been to one. WHAT ARE YOU WAITING FOR?!

This was my 6th event with Highlander Assault. Every event is better then the last. The organization is always improving, the staff is always happy and having fun. Have never ran into a less then friendly participant. Obstacles are well built, course always evolving and fun. I cannot wait to conquer the gauntlet next year.
