CYCLO X finds its home on Nov 10th at the suprise venue of 2011, Sienna Lake in Broomfield. Once you arrive you'll think the city built this park in 2010 with one thing in mind, cyclocross. If you like Interlocken then get ready for another lush grassy course with sloping hillsides. This is the most spectator friendly venue out of the entire CYCLO-X and Boulder Cyclocross Series, so grab your friends and family.
