I took some of these, but the good ones are from Nuvision Action Image and provided free to Spartan racers.

The glorious start of battle
It doesn't look like it from the expression on my face, but this is actually fun
Who doesn't like running uphill through mud to jump over roaring flames!
Not my most graceful jump ever
At this point the race is virtually over...just a few obstacles - no more running
Taking my beating from the gladiators at the end
You'll know at the finish line!
All cleaned up and ready to enjoy the rest of the weekend
