Bone Frog Challenge
Berkshire East Ski Resort
9+ Miles. 36 Obstacles. Hills. Mud. Harder than Hell. Join U.S. Navy SEALs for an event you will never forget. With a minimum of 36 Navy SEAL-style obstacles spread out over 9-12 miles, the course will test everyone and leave no one unscathed. We place an obstacle approximately every 1/4-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.
