The Denver Colfax Marathon returns this weekend to celebrate its 20th anniversary [1] with a theme titled "Wow at Every Mile."

This milestone event transforms a major city artery into a massive athletic and cultural festival, impacting local transit and drawing thousands of participants to the U.S. capital of the Mile High City.

The celebration takes place on Saturday, May 16, and Sunday, May 17, 2024 [4]. Organizers have planned eight separate races over the two-day period to accommodate various skill levels and distances [2].

To maintain the high energy of the event, the course will feature 40 entertainment acts [2]. These performances are designed to provide a continuous spectacle for the athletes and spectators as they move through the city.

Officials expect more than 27,000 runners to participate in the festivities [3]. The high volume of participants and the location of the races primarily along Colfax Avenue are expected to cause detours and delays for RTD bus and light rail services [5].

The "Wow at Every Mile" approach aims to blend competitive athletics with community entertainment. By integrating dozens of performance acts into the race route, the event seeks to distinguish itself from traditional marathons through a high-density entertainment model [2].

Participants and residents are advised to monitor local transit updates due to the extensive road closures required for the 20th anniversary celebration [5].

The scale of the 20th anniversary event demonstrates the evolution of the Colfax Marathon from a standard race into a large-scale urban festival. By prioritizing entertainment alongside athletics, the event increases its economic impact on Denver but creates significant logistical challenges for the city's public transportation infrastructure.
