DENVER -- The Colfax Marathon is this Sunday and thousands will take to the streets during the 26.2-mile run through one of Denver's most famous arteries. 

But if you're not participating, here's everything you need to know about the event: 

The Colfax Marathon

Billed as the “ultimate urban tour,” the mile-high course takes runners on and off Colfax, through parks, neighborhoods, trails and downtown.

Participants will have a chance to enjoy amazing views of the Front Range, Confluence Park, Sports Authority Field at Mile High’s concourse and the Cherry Creek trail.

For those not participating, don’t worry – there’s an after-party event in City Park with live music, food and drink.

The event starts at 5:30 a.m. and will go until about noon. 

The route

The Colfax Marathon will start and end at City Park but the route will take runners all the way to Garrison Street near Crown Hill Park in Lakewood to the west, and up to Havana Street near Aurora to the east.
