context_page_description: The Colfax Marathon, previously known as the Colorado Colfax Marathon, is an annual marathon foot-race established in 2006 in Colorado, United States. The course followed Colfax Avenue for 26.2 miles, starting in Aurora, heading west through Denver and finishing in Lakewood. About 6,000 people took part in the inaugural event in 2006. The course changed in 2008 to start and finish in Denver's City Park, with only portions of it on Colfax Avenue. The full marathon heads west to Lakewood and back; the half marathon east to Aurora and back.
  In addition to the main event, a half marathon, a relay and a new 5K race also take place.
  The 2011 Kaiser Permanente Colfax Marathon, Half Marathon and 5-person Marathon Relay were held on Sunday, May 15, 2011. Start and finish points were in Denver’s City Park. In between, the new marathon and relay course hit all the high points: vibrant Colfax, the Capitol, downtown, Cherry Creek Trail and Confluence Park, Invesco, plus eclectic, artsy neighborhoods in Lakewood. Runners loved the half-marathon course through Denver and Aurora: flat, fast and shady.
