In the current era of ocr, big name races are getting weak with their obstacles and course designs. Frontline ocr came out swinging and didn't pull any punches. This was easily the most challenging race I've done thus far.

Frontline OCR Exceeds Expectations

Aug 29, 2017 by Sylvia L.

Frontline OCR 2017 exceeded my expectations. From the initial jump into an "LCA" while Coach Pain reminded us of the bravery and sacrifices made by men and woman on our country's behalf not only humbled me but inspired me to do my best on this new course. But it didn't stop there, I truly enjoyed and appreciated the variation in mental and physical challenges.

Having raced quite a few other OCRs, I was pleasantly surprised by how organized and easy it was to park and check-in. No hassles whatsoever. In addition, the volunteers were great-spirited and very helpful.

All in all, I absolutely loved and supported the cause as well as the tough and innovative obstacles. It was win/win all the way, and Truth be told, I could not stop smiling for quite a few days. I'm very much looking forward to racing the Frontline in 2018.

I've run 30+ OCRs over the past few years, many with my children. My son said this is his favorite, hands down. I love that they brought military/police/fire style and theme obstacles. This race left muscles sore that I usually forget about.

Can't wait till next year.

Race and course review

Aug 28, 2017 by Dustin firkin

Race was inovative which is hard to do these days, obstacles made you use everything you had. It was one of the best courses i have seen coming out of Illinois you had to be a well rounded athelte to be competitive being a runner just would not cut it. The endurance class was a blast and i would recomend it to anyone.

Tough but FUN!

I had a blast on this course, but boy was I sore the following week. The course used every bit of the hills in the area to make Illinois usually flat land a challenge. The new obstacles were a nice change of pace from more of the same. The distance as ruined me for shorter courses because they just aren't long enough! The staff and volunteers were very friendly. They were easy to spot in their day-gloe shirts. I look forward to the Frontline 2018 season!

The Frontline OCR race is an experience you cannot pass up. This race will test your mental and physical toughness and your grit, if you have any, to complete the course. Even for the toughest of elite ocr athletes ... you better come prepared for miles of insane obstacles that will use every single muscle, tendon and mental piece of your body. My good friend Ed Leon and his amazing Frontline OCR crew and family have put together this military inspired obstacle course which I highly recommend to everyone looking to challenge their ocr skills and mental toughness. Next wave to be announced soon! Come test the course ... IF YOU DARE!

At the Front of the Line

Aug 28, 2017 by Ryan Hart

Being an owner of an OCR Training gym and an avid OCR competitor, I've participated in tons of OCR's, many of whom were only in their infancy. The experience that myself and members of my team who both participated or volunteered were awarded was truly something to behold for any race, much less a local groups inaugural event.

Frontline OCR was as organized, if not more so, than some of the much bigger race companies that have been at this for years. From parking to volunteer distribution at obstacles and water stations, the careful planning of Ed and his crew was as evident as the time put in to the course challenge and obstacle safety.

Having the most unique approach to an OCR to date with their blitzkrieg event to decide the winners was the icing on the cake for an event that already stepped outside the norm and into their own realm by dressing their elite athletes in weighted vest instead of wristbands.This in itself properly summarized the difficulty and fun of their signature approach in addition to their inclusion of both an endurance and open class to take on their warped walls, irish tables and Platinum Rig, just to name a few. Endurance athletes, while not equipped with a vest, earned a dog tag for each lap completed.

Throughout the distance of this well developed and challenging 5 mile course you could see members of the Frontline crew eagerly running around and systematically communicating, passionately concerned for their racers safety, compliance and course's completion.

The medals, t-shirts and race swag was top notch as well, and never once during my 3 laps of my endurance run, did I ever get the feeling that this was anyone's first attempt at an OCR race. As an owner of a facility which boasts many of it's own obstacles, I have a huge amount of respect for the commitment of time, finance and planning that goes into the development of an OCR training facility, much less an actual race and am unbelievably impressed with what Frontline was able to pull off.

There were literally parts of the race that I was saying out loud to my wife "how did they do this and get it so right the first time?"

In closing, I would highly recommend Frontline OCR to anyone that missed out on their inaugural race, and confidently persuade them to pursue any of Frontline's future endeavors whether races or workouts. Their military and first responder approach and appreciation commands the highest respect, and their race is a proper representation of respect to them both.
