So me and a Friend did this Bone Frog Navy Seal Challenge Obstacle Run in Charlemont, MA. And it was one of the hardest run’s i’ve even done, it was Def. the Longest at over 8 Hours of none Stop Running/Climbing/Crawing I was Toasted after this run. Tier-1 was the level we did with 9+ Miles and 50+ Obstacles up and down a Ski mountain it was a Killer! If you are thinking of doing this run then def. watch this video to see what you are in store for!
