What have I done?

Oh my good Lord, what have I done?  I have gone and signed up for this.  To say I'm scared would be an understatement.  I think I can handle the running part (trail and uphill) and the mud, but the obstacles have me terrified. 

I signed up to run the Spartan Sprint in Palmerton, PA on July 14th.  It's a 3ish mile obstacle course with approximately 15 challenges.  I'm not worried about the rope wall or belly crawling under barbed wire.  But, anything that has to do with upper body/arm strength?  Screwed.  What's fun about this one, unlike many other mud/obstacle runs, is for every obstacle you miss, you have to do 30 burpees.  What are burpees?

1. Get into a crouch
2. Kick your legs back as if doing a push-up/plank
3. Bring your legs back into the crouch position
4. Stand up
5. Repeat 30 times

So, if you miss all 15 obstacles and do 30 burpees each you would be doing 450 burpees.  I honestly can see myself doing a good number of that total.  I suppose I should practice these things...

Cause finishing means I get one of these...and they are kinda cool...
