The Colfax Marathon is Sunday. Here’s what to know about traffic disruptions

If, like me, you are a mere mortal whose sole plans for this Sunday involve eating a bagel, beware of detours and road closures due to the Colfax Marathon.

From 6 a.m. to 2 p.m. Sunday, here are the altered Regional Transportation District (RTD) routes:

• The D and H lines will not stop at Colfax at Auraria station through the downtown loop
• The D and H lines will detour to stations at Auraria West, Empower Field at Mile High, Ball Arena, Elitch Gardens and Union Station
• The L line will not run (RTD suggests the 43 bus instead)
• These bus routes will have detours: 0, 1, 6, 8, 9, 10, 12, 15, 15L, 16, 19, 20, 24, 28, 30, 38, 43, 44, 48, 51, 52, 76, 83L
• On Saturday, routes 20 and 24 will have minor detours from 9 a.m. to 12 p.m.

RTD also said riders should expect delays. And on Sunday, RTD says it's accepting race bibs as a form of fare payment on the W, 15, 15L and 16, from 6 a.m. to 2 p.m.

Drivers, pedestrians and cyclists will not be able to cross the course, pictured below in blue, while the race is taking place. Road closures start at 6 a.m., and will open on a rolling bases once the final runner passes through each area.
