While most of us are spending eight hours a day for the next four days watching college hoops (and possibly recovering from vasectomies), there always has to be that one overachiever making the rest of us look lazy.

Enter Dean Karnazes.  Not only is Dean running the Los Angeles marathon on Sunday, he’s getting to the marathon by taking a 5-day, 500-mile ride from San Francisco on his ElliptiGo — half bike, half elliptical machine.

It’s not Dean’s first crazy stunt — he’s run for 82 consecutive hours, and done 50 marathons in 50 days.  He’s also tweeting from the road which you can follow @elliptigo, if you’re into that sort of thing.  (Personally the name reminds me of the OptiGrab from The Jerk, with hopefully less severe side affects.

Here’s video:

Want your own ElliptiGo? It’s around $2,000 now, but the makers are hoping to cut that price in half soon.
