Derek, are you familiar with MovNat? Seems like that might be a good program for this. MovNat focuses on 12 essential skills
At least eight of those skills will be in an event like this, at least from what I saw in their videos. Definitely climbing looks like it's pretty crucial. http://www.americanparkour.com/MethodeNaturelle.pdf
That is the Methode Naturelle partially translated to english with an excellent section on jumping and climbing.
