Have you ever wanted to try an obstacle course race but felt intimidated by the thought of running? Alpha Warrior may be the  race for you.

Supporting the Challenged Athletes Foundation’s Operation Rebound, Alpha Warrior offers a new take on obstacle course racing. Instead of focusing on miles, the race consists only of challenges that target specific muscle groups to test both mental and physical athletic ability.

The inaugural San Antonio race event was sold out, inspiring the Alpha Warrior team to create five more this summer. This Saturday and Sunday will kick off the second event at Qualcomm Stadium in San Diego.

Upcoming cities on the Alpha Warrior tour include Dallas, Phoenix, Oakland, Orlando and San Antonio (next year). Visit the Alpha Warrior website to register. Sign-ups are limited but still available for all dates.

To find out what it’s like to participate in an Alpha Warrior race, check back with STACK next week. Operation Rebound athlete Charles Linville (U.S. Marine Corps), a below-the-knee amputee, will be participating in Alpha Warrior San Diego and writing a guest post for STACK about his experience.
