The Colorado Trail MTB Race started this morning and can be tracked here: http://trackleaders.com/ctr
I see Erik Lobeck is running strong. In comparison to The Tour Divide Race it's short, but the terrain is mostly technical singletrack riding. These racers cover a lot of ground.

Good luck to all,
