Road closures for the Denver Colfax Marathon: How to get around it
DENVER (KDVR) — The Denver Colfax Marathon is this weekend, and thousands of runners are gearing up to run through the city. With the marathon also comes many road closures through Denver.
The Colfax Marathon kicks off on Sunday and goes through the heart of downtown Denver and into Lakewood. From 5 a.m. to 1 p.m., there will be several road closures and detours with bus routes and light rails.
Roads are closed from City Park toward Crown Hill Lake. While many main roads in Denver will be closed on Sunday morning, there are ways to get around it.
If you're looking to get from one side of the city to the other, the marathon recommends avoiding the pink-shaded areas on the map below:

North and south
If you're coming from the north and heading south, or vice versa, Interstate 25 is open to get through the city. However, if you're looking to avoid the marathon madness altogether, these are the closest roads around the marathon loop:
Head east to either side roads off Colorado Boulevard or Monaco Parkway
Head west by taking Kipling Street or side roads west of Garrison Street
East and west
If you're looking to head from east to west, or vice versa, the best way is to go around the marathon loop.
Head north and either take part of West 29th Avenue or West 32nd Avenue
Head south and take 13th Avenue or West 10th Avenue
While there will be road closures in the area, the marathon said roads will be open and closed on a rolling basis as runners pass the areas.
