The XII is a 12-hour endurance evolution presented by the Green Beret Challenge. If you have already participated in one of our events, you already know we have set the new standard in Endurance Challenges. Participants will be exposed to what it takes to make it through Special Forces Assessment & Selection. This unique experience is delivered within a very unique endurance challenge format.

Phase I: Experience a little taste of what goes on at Special Forces Assessment & Selection (A&S) most folks will never get to see or understand. Expect to be tested individually throughout this phase of the XII. You will be expected to ENDURE numerous Special Forces physical fitness events… The XII will be limited to the first 100 Candidates.
