Tac Force Challenge, Franklin

Tac Force Challenge tests the strength of racers by putting them through the rigors of an adventure 5K obstacle course designed by power lifters, martial-arts experts, and special-operations professionals. The muddy, muscle-straining course houses 31 obstacles, such as rope walls, river dashes, unbalanced beams, log trips, and tunnels that force runners to use all their strength and jet-pack fuel to reach the finish line. Participants begin their first race ranked as a Private and advance closer to General as they complete each run. This progress is saved in the Tac Force database, which catalogs completion dates so that the government knows whom to call in the event of a sweaty-bicep shortage.
