What makes Spartan extreme and unique?

Wondering what separates Spartan Race from other obstacle races?

The clock.

If our courses do not kill you outright, our clock will. This is not just a "trail run" or any old "mud run", it's a race. Most anyone can manage 10 miles and some obstacles, but we present you with the ability to hit the course hard and see how you rank. Not just against the competition, but also against yourself. We want you to shoot for PERFORMANCE and reach it.
