Mark Short Bio

I did my first adventure race in the Fall of 2000. Since then, I've done over a hundred more adventure races and quite a few solo rogaines. I'm often the navigator for my team, though not always, and rarely for an entire expedition race. I love to be out in the woods with just a map and a compass (and my dog). There's something very satisfying about finding one's way across a wilderness area - whether on or off the trails. For me, it doesn't get any better than bushwhacking across some diverse terrain all night long heading for a hard-to-find checkpoint. And I seem to learn something new at every event I attend.

Here's something fun I put together when someone recently asked me how many races I'd done. In addition to being a geek, it might be time to start an AR Anonymous group...I think I have a problem.
