For those of you former MX'ers, you might be interested in watching this when it comes on TV. I follow Doug and David on FB and they posted they are riding as a team, along with 2 other able cyclists. I have watched it before and it is fascinating because it's like the Iditarod, in that they do almost everything on the bike with little sleep to see who can get from CA to MD the fastest. I'm sure Doug and David will make it competitive even with able riders since they are such strong athletes!
