Soldiers assigned to the 1st Brigade Combat Team, 1st Cavalry Division, begin to run at the start of the Tough Mudder Centurion Challenge, April 21. The course hosted a plethora of obstacles including: a tire-drag, incline-decline monkey bars, spider-man wall-traverse, balance-beam cross over water and a low-crawl. The challenge was to complete the course in the fastest time possible, and any penalty accrued by a team member added 10 seconds to their team’s final time.
