How Do You Prepare for a Trail Race?

For me, it's important to race to see how my body is doing andn different distance. The next one i'm going to do is carson's pyramit - a rock climbing mountain in indonesia. So for it has nothing to do with running. It's really scrambling and scrambling fast. Right now. I'm starting with jim. I have to win some weight,. I have to do some push ups. And this is something that i really enjoyed so i don't get bored.
