This is my second time running this event, they keep on upping up their obstacle games. Totally awesome local OCR event, not only they support the armed forces but they come up with challenging obstacles every year. Sign me up every Wave.

Amazing race this year!!!! The obstacles and rigs were top notch!! The trails through the woods were great! One of my favorite OCRs around. This was my second time running at Frontline, I will be signing up for next years!

This is my third year in a row and it seems this race only gets better and better. The first year I volunteered and the last two I’ve raced with my F3 crew. Hats off to the whole team, excellently put together!

Frontline 7th Wave

May 31, 2022 by Mike Olson

3rd OCR, 1st with Frontline. Everything was challenging but you could go at your own pace, you vs you. Great obstacles and great runs between. We didn't wake up for easy and Frontline OCR made sure of that!

Excellent race! Obstacles were innovative, challenging, and extremely well-built. Course was terrific and very well marked. Great race with options for all levels of athletes, from elite to new-to-OCR.

Frontline OCR 7th Wave

May 30, 2022 by Paul “Captain” Sparrow

This year was my 5th Frontline OCR. If you’re on this site, there’s a good chance you think you’ve seen it all when it comes to OCR. Well if you haven’t done a Frontline, you most definitely have not seen it all. All OCR’s are NOT created equal and Frontline proves it. The obstacles are brilliantly engineered and strategically placed to challenge the will of even the most experienced OCR athlete. The Special Forces wave is truly unique in the world of OCR. The weighted vest takes familiar obstacles and dials the difficulty level up to 11. Once you’ve tasted that challenge you will hunger for more and more. That’s why I’ve done the last five events and why I’ll keep coming back. You owe it to yourself to experience the challenge and fun of this unique event.

This was my first time at this event. I have been participating in OCR for almost 4 years and by far this was a top 3 course! The obstacles were difficult, but it didn’t matter because of the fun I was having. The trail was beautiful and course well designed. I will definitely go back next year!

1st Timer and addicted.

Some said it would be fun.
Others said you can do it.
Hootie said you’ll be addicted.
All the above turned out to be true.
It was my first OCR and with the Frontline organization not only was it important in supporting what they stand for but also F3 Hootie’s lead, my hesitation quickly turned into a no brainer. Especially after completing it.
also doesn’t hurt when running a group of dedicated buddies. On the fence? Just do it.
