Looking to test your endurance at 5280 feet above sea level? Then you may want to check out the Colfax Marathon on May 16th starting and finishing in Denver’s City Park. The 26.2 mile race runs down a portion one of the most famous thoroughfares in the United States, Colfax Avenue, and offers excellent views of downtown Denver and the Rocky Mountains.
During its inception in 2006, the race ran down almost the entire length of Colfax, which is the longest city street in the United States, stretching from Aurora to Lakewood and running through Denver. However, since 2008 the course only covers a portion of the thoroughfare. Still, it’s enough to get a glimpse of a street that was once described by Playboy magazine as “the longest and wickedest in America,” because of its association with prostitution as well as an abundance of cheap liquor stores and bars.
The race runs for about 3 miles through City Park, until it veers down Colfax at Mile 4 and runs straight until Mile 13, passing by such landmarks like the Cathedral Basilica of the Immaculate Conception, the Colorado State Capitol, Civic Center Park, and the Denver Mint. After a hairpin turn, the course veers back down Colfax to Mile 17.5 and heads toward downtown Denver, where a slight hill between Mile 22 and 23 is the last challenge before a relative straightaway back to the park.
