Book Review: Strength and Speed’s Guide to Elite Obstacle Course Racing

By |October 5th, 2017|

In a world where information is “literally” (with a British accent) at our fingertips through the infinite knowledge that is the internet one can find almost anything he/she chooses. Heck, I can simply speak the words “Ok Google” into my phone and my Google Assistant is at my beckon call. However, this plethora of information [...]

OPINION: Talking Toughness

By |February 16th, 2017|

January 2017 marked the end of an era as the Tough Guy Race in the UK put on its last event. In reading about it and watching videos I began thinking about the idea of “Toughness” and how this notion of being “tough” or at least trying to teach this attribute has actually spawned the entire industry of obstacle racing (OCR). In fact, this belief that an OCR is basically a sport of suffering is eloquently described in detail in Scott Keneally’s documentary Rise of the Sufferfests. Tough Mudder has doubled, actually quadrupled down on this idea with their creation of the Tougher Mudder, Toughest Mudder, and the World’s Toughest Mudder events. The question is what does it really mean to be “tough”?

Greetings from the Blue Mountain Corral

By |October 31st, 2016|

It was a cool morning on the banks of the Gregorian Bay. However, we expected much worse from Mother Nature in October. We are in Canada! As I stood there in the start corral for the Pro Wave of the 2016 OCRWC, I found myself wondering...

  • Thermoregulation for OCR

Thermoregulation for OCR

By |September 21st, 2016|

The sport of obstacle course racing (OCR) basically prides itself on the races being sufferfests. Heck Scott Keneally’s new documentary about the sport is even titled Rise of the Sufferfests. Some of the most memorable scenes in this movie are the visuals of the participants battling hypothermia after completing the events.

Race Recap: Green Beret Challenge – Commando Course

By |September 1st, 2016|

Coming into the Green Beret Challenge (GBC) the only thing I knew about it was that there were a lot of heavy carries. I read up on it a bit, and it sounded like a fun event where the owner, Mark Ballas, and his band of merry men would try to give you a taste of team building; Special Forces style. This particular race took part deep in the backwoods of south central Missouri just on the outskirts of Ozark mountain country. As with a lot of the OCR event’s these days the venue itself was one of the biggest obstacles for the organizers who ended up spending much more time than planned prepping the trails.

BattleFrog Cincinnati: The Finale

By |August 25th, 2016|

I believe that any OCR held at the King’s Domain site just north of Cincinnati has the potential to be an epic event. It has everything an obstacle race should include; lots of woods, a mix of dirt and rocky trails, crazy steep inclines, and obstacles, oh so many awesome obstacles. BattleFrog utilized this course to put on what many believe, myself included, the toughest regular OCR ever put on in August of 2015.

Opinion: Are Pro Team Athletes Doing Enough for the Sport?

By |August 11th, 2016|

Pro teamers race hard and inspire us all with their performances but what if their presence at an event meant much more to building a brand and making the race experience that much more memorable for those out there participating?

Race Recap: What is Conquer The Gauntlet?

By |August 8th, 2016|

I have heard a lot about this race company Conquer The Gauntlet (CTG) who puts on races primarily here in the Midwest where I live. Until this weekend, however, I had never actually done one of their events. I had heard about how their obstacles are brutal and how only a select few can actually finish the races with their bands (it’s a belt in CTG). I guess your question could be, “were you nervous?” I am always nervous coming into a race, or more like fired up. Nervous isn’t a good way to explain the way I feel going into a race. Am I nervous about The Cliff at World’s Toughest Mudder? No but it does give me that feeling in my stomach when I look over the edge.

Race Recap: BattleFrog Greater Kansas City

By |May 2nd, 2016|

This weekend was my first obstacle race of the 2016 season and I decided to start it with a bang at Battle Frog Greater Kansas City which was actually held in Topeka, KS… Don’t get me started on this practice by obstacle racing companies of naming a race location by its closest major metropolitan area and not the city/ state in which it’s actually located, but I digress. I have been training long and hard on obstacles since my last Battle Frog event and was looking forward to testing my metal after all this training.
