The "boots" thread got me thinking a lot about adventure racing. I really like the premise of that race but 30 miles is going to be a little too much for me, currently anyways. I really want to register for something that will give me motivation to work out and train on a regular basis.

Anyone know of any good ones? I like the idea of a shooting/ obstacle race but I'm thinking I'm not likely to find something like that. How does someone get started in something like this? I assume the short 5K races are the best for a newb.

Thanks in advance for the help.
