The Story
The Bone Frog Challenge was created by Navy SEALs to challenge, build and inspire participants to become better athletes and recognize that they can do anything they set their minds to, while enjoying the camaraderie and teamwork usually reserved for active duty Navy SEALs.

The Course
With at least 36 military-style obstacles on courses that range from 9-12 miles, the course will test everyone and leave no one unscathed. We attempt to place an obstacle about every ¼ mile, so your running ability alone will not carry the day. You must be functionally fit to succeed here. You will get muddy. You will get beat up. You will be exhausted. But you will finish. Did we mention sand? You will get to know what it means to be “wet and sandy” just like we were at BUDS. As Navy SEALs, we know what tough is – and we don’t mean Harvard.

Team or Individual
Our event will foster camaraderie, period. Form a team ahead of time or link up with others when you get here. This is a great way to challenge your friends and create lasting bonds.

Family Event
As Navy SEALs we have been forced to spend a great deal of time away from our families. As a result, whenever we can, we include the entire family in all that we do. The Bone Frog Challenge event weekend offers fun and activities for all ages for only $10 for the whole day! Let the kids come watch you race and then let them loose in our Mini Bone Frog Challenge Kids Area where they can play in the mud and on scaled down obstacles.

Amazing experience!!

Nov 19, 2017 by Reaper 7

I’ve competed in many obstacle courses prior to this one.All great in their own way, but none had the same powerful patriotic feeling like this event. From the huge American flag to the silent professionals, The “voice” and DJ included, to the determined competitors and participants and the very reasonable merchandise prices, this experience was worth every penny!! I really hope it becomes as big as the Spartan, this experience needs to be shared with every Patriotic and grateful American.

Finished this race earlier today. I did the TIER-1 race. Totally worth it. Make sure to look for email prior to race about checking in and picking up race packet the day before. Well worth it. Just park and go the morning of the race. This race has less participants than a spartan race, which I’m fine with. Way more manageable and quick. Race crew are super friendly and cool. Some of the o stacked need to be modified. The grenade throw needs to be limited to three try’s max. to prevent back log. Also the helicopter monkey bar needs netting or closer to ground. I saw too many people eat it hard and one lady got knocked the fuk out when she fell. All in all, I dig this race. Liked it better than Spartan. Like how they support the troops. As a former Navy guy, I got a little choked up at the memorial wall on the course.

Bonefrog Challenge Atlanta 2017

Oct 18, 2017 by Brandy

I have run several of the major OCR's as well as several not so name brand ones. This was my first Bonefrong Race. I ran the Tier 1 open which consisted of 12+miles and 50+obstacles. While I can say for the most part it was pretty awesome there were some pros and cons to the race.


-The Venue was held at an ATV, MX park which provided lots of hills and trails to test your endurance.
-There were a lot of new and challenging obstacles as well as some familiar ones.
-The lines were not that bad at any of the obstacles and seemed to flow well.
-Black Ops had some what of a wait but only when someone would slip off the monkey bars and fall to the net below.
-The trail and paths were well marked.
-Tier 1 participants received a large well made medal for completing the challenge and the sprint.


- I was one of the first vehicles to arrive at the venue because we drove through the night to get there. It was still dark when we got there. The signs to the venue were lacking and it was easy to go past the main entrance to the park especially if it was still dark out.
- The parking could have been better. I felt our spot was bad even though we got there early.
-There were two options to get to the registration tent. You could either go through a trail, (it was still dark and we didnt have a flashlight) or you could trek half a mile or so up a dirt hill to get to the tent. Because we had a wagon with our stuff in it and no flashlight we chose the road which was dark.
-There were plenty of water stations on the course but the stations were lacking any type of energy food or electrolytes.
-It would be nice to have a boost of energy available especially if you are running the endurance or Tier heats. Even tough mudder provides some sort of electrolytes or energy boost at the water stations.
-Obstacles like the rope climb and the sternum breaker(I can't remember what they call it) need some type of safety features like hay or straw below them in case you fall. I personally do not like the sternum breaker. The first time I went over it I had some assistance on the way down off top log. The second time around there was no one to help me down and I fell from the top and onto my hip on the hard ground. I saw several people get hurt at this obstacle.
-The finish line provided tiny cups of water but did not provide any type of fruit or energy food for recovery. For the price I was expecting at least gatorade or a banana or something to replenish what was burned on the course.
-There was only one food vendor. I can not speak for the food because I did not eat it.

All in all the race kicked my butt and I would probably do another Bonefrog but would like to see improvements on the course and more safety features.

Makes Killington Beast look like Chuck E. Cheese ball pit

Sep 30, 2017 by Jeff

Hardest mofo OCR ever. I've ran tons of spartan races- sprints galore, supers, beasts and even did an ultra beast in Killington. Those pale in comparison. Only issue i had was that at mile 7, i had to take huge dump, so i had to wade into the water and peel down my compression shorts to drop a duece in the water. Felt bad haveing the other competitors wading through that water after my dump, but that's life.

Bone Frog Challenge Berkshire East 2017

May 29, 2017 by Ken Flood

So, my first Bone Frog. Done oodles of Spartans, couple Battlefrogs (RIP), etc.. The Course = nice and tough-check, imaginative obstacles-check, big friggin mountain-check...WHAT, Norm Koch designed it.. honey I may be home a little later than I thought tonite.

First the positives:
- This was HARD, 40 obstacles on a psychotic 3 ascent/descent course. It will test your grip and reach muscles far harder than even a Killington Beast.
- The obstacles have very few "gimmies", and some are really complex where you need to stop and plan your attack, seriously.
- Penalties are posted at each obstacle, and they vary from burpees to jumping jacks, etc..Thumbs up.
- They managed to find space for some open trail running which was nice. And it was cool running past a solar farm, and close up to a giant wind turbine.
- Water stops were plentiful, though they should just have water bottles set up and volunteers handing out cups instead of trying to fill them one at a time.
- Parking was right at the gate, and the base area had a good amount of room, food, vendors and porta-potties.

- The registration line was poorly done. Was 1 line for all, took FOREVER. They need to set up like Spartan, multiple lines.
- Shower area was a few hoses and only 5 wood pallets to stand on, and no changing tents !
- There were long lines for Sway Bars and Slide for Life, needed more than 3 lanes on the Bars, but a pass on Slide as we were all glad for the break at that point.
- Not consistent enforcement of the 1-attempt rule. On some of the easier obstacles people were just doing them over and over, wasting everyone's time.
- I know the Dirty Name is a signature obstacle, but this is a really dangerous one. They need to put a net underneath, you hit that top log wrong and you can break your sternum or shoulder. Fall off and break your neck.

But all in all, the negatives are minor'ish quibbles. The race was hard as hell, good photos, made some new friends :), cool medal, and the burgers were REALLY good. I will be doing another Bone Frog next year.

Bone Frog Challenge Tier 1

May 03, 2017 by Chad

First off forget the AROO AROO AROO Spartans...there is a new breed of warrior in town, HOOOOOYAH Bone Frog SEALS! What a blast, what a venue! You will get every bit of your monies worth and then some. I'm retired Navy so of course I was all in to see what some fellow sailors had achieved in getting into the OCR world and decided to go big...why not go big or go home so I chose to do the Tier 1 Elite challenge (Endurance, their newest race was not out at the time). Hells Yeah if you want sweet glorious masochistic soreness and sprinkle in some pain then look no further! If you want to push your body then look no further! I'm not going to give you play by play details about the race or this or that. Its is up to you to get your butt to a Bone Frog and experience it for your own and make your own story book about it! I will be doing it again for sure but taking on the Elite Endurance next go round. So "Get After It"!

My daughter and I love doing OCRs together. We have completed 5 Warrior Dashes, 2 Tough Mudders, a Spartan Military Sprint (another scheduled for this year), a Savage Race (another already scheduled), a Rugged Maniac, a Terrain Race (10k), a BattleFrog (RIP) & other various local races. We are not elites but rather a team that likes to challenge ourselves while having a great time. We have been trying to hit each of the majors/mid-majors so when Bonefrog came to Talladega, we jumped at the chance to do it. We signed up for the 8+ mile Challenge and it ended up being close to 9 and I have to say this was one of my favorite races yet! It started off with the best Motivational Starter in the business, Coach Pain. We had him for the first time at our BattleFrog event last year and was stoked when we found out BoneFrog got him for this race among others. I know some people dismiss the importance of the start line but it is one of the things I really judge races on after the obstacles. Once Coach Pain got us all hyped up and going the course itself was different than any other OCR I have done. Their goal was to test you and push you to the limit and mission accomplished. I never felt in danger but was pushed to my limit. They used everything around such as the grandstands (Wreck Bag carry up and down the grandstands almost pushed me to the limit but the sense of accomplishment once I finished was unbelievable) I also love the fact that the penalties were not the same throughout the course. The obstacles had penalties but they varied on each one. One could be 30 burpees while the other could be 25 push ups, etc. That made for a much better experience IMHO (My daughter said the same thing.) Also the fact that they incorporated emotion in it with 31 heroes and the Memorial wall was also a great thing. I can not say enough about this one. I am considering Atlanta in October and if they come back to Dega next year I KNOW we will be back!

bonefrog challenge berkshire east

Nov 05, 2016 by Lance Zaleski

I have to start by saying I did not do my homework when it came to the Bonefrog challenge, Berkshire East. With that, I mean, this was literally the first obstacle course race that I have every run. To say the least I was in over my head, but have been indoctrinated into the never quit mindset and without that I never would have finished this course. Being prior service I have learned that your body can do whatever your mind allows it to do and that alone is the only reason I finished this course. To say I got my ass kicked is an understatement, from obstacle # 2, water crossing to the stairway to Valhalla, to Hells Gate, it was a constant ass kicking roller coaster. From the event coordinators to the polite and respectful staff and volunteers, you cant beat the comradery of this event. If you walked away from this event feeling alone, or defeated, you never opened your eyes, to the mountain full of people suffering along with you. I was proud to finish this course, proud that my son walked across the finish line with me and most of all proud to support the warriors that defend our rights and allow us to participate in events like this and live a life of choices. I finished, yes my ass was dragging, but my pride was intact, not only am I coming back for more, but I'm bringing more warriors with me. hooyah!!

Bonefrog Carolina 2016 Tier-1

Jul 28, 2016 by Jim Young

13+ miles (think its actually 14+) most miserable experience Ive had in along time, I loved every minute of it. Tested physically & mentally.
Tough hills, the mud was like molasses.Obstacle were top notch. The 109 degree heat was an obstacle as well. I would suggest more water stations. The medals are nice design, the Tier-1 Finisher shirt is the best looking shirt out there. This a great OCR event. I will do this one again.

May 23, 2016 by William Beck

All my races to this point have been easy local races. This was brutal. Fun, challenging, packed a lot of different terrain into a race held at one place. For me the the obstacles were manageable, not easy but could do them. If there was a down side, water stations were empty towards the end. I went in the 11AM wave. Going back next year.
