Marathon world champion Sauser takes on Leadville 100

The Leadville 100 mountain bike race has the reputation of being the most difficult one-day race in North America. There are plenty of other 100-mile races that have equally difficult terrain and altitude, but none have attracted the star power of the Leadville 100. Consider the likes of Lance Armstrong, Levi Leipheimer (Omega Pharma Quickstep), Todd Wells (Specialized), Jeremy Horgan-Kobelski (Subaru Trek), and Dave Weins (Topeak Ergon) driving the pace of a peleton that may contain a couple dozen of the best distance riders in the world.
