The 20th Colfax Marathon and its associated races will kick off Sunday morning with more than 28,000 expected to take part, causing road closures on Colfax Avenue and some downtown streets.
In addition to the 26.2-mile marathon distance, there will be a half-marathon, 10-miler, and marathon relay. The half-marathon and 10-miler are sold out.
East Colfax Avenue will be closed between Colorado Boulevard and Garrison Street in Lakewood. Downtown, 17th Street and part of Larimer Street also will be closed. Street closures will be imposed from 5 a.m until 1 p.m., but some streets will reopen before then on a rolling basis.
“A 20-year milestone deserves a big celebration,” said Andrea Dowdy, chief executive of the Denver Colfax Marathon, in a news release. “There is so much excitement in the city right now, and we are grateful to our runners and our community for growing this tradition into Denver’s biggest running weekend of the year.”
