On Friday, May 21, 2010 the world’s top professional cyclists including Lance Armstrong, Levi Leipheimer, Dave Zabriskie and George Hincapie will battle it out on the tour’s most challenging route known as the queen stage. The route from Pasadena to Big Bear Lake consists of 135 miles and more than 12,000 feet of climbing. The grueling queen stage is specifically designed to challenge cyclists, and should have a significant impact in the overall standings of the AMGEN Tour of California (ATOC).
