Colfax Marathon

Run to support Mapleton students!

Colfax Marathon | May 18-19, 2024

Colfax Marathon is Denver’s largest running weekend! You have days of fun with the expo and myraid of races. Distances are approachable for all levels of runners and walkers. Colfax course distances include the Marathon, Marathon Relay, Half Marathon, Urban 10 Miler, and a 5K.

One of the unique items about Colfax is the race’s focus on nonprofit partnerships. That’s where the Mapleton Education Foundation (MEF) comes in! As a Colfax participant, you can choose to run for a designated nonprofit. Each nonprofit runs their program in a unique way. MEF focuses on an encouraging, supportive environment. Running for MEF, you can help fundraise to support MPS students across the entire district. That includes more than 7,000 students across more than 20 schools. Not a fundraiser? Some runners are more comfortable making a personal donation to MEF. Others become ambassadors for MEF and help raise awareness about the important work MEF does and the impact it makes for MPS students. Signing up to run with the Mapleton Education Foundation does not require you to do anything extra. We appreciate any and all support you may be able to give and we look forward to encouraging you on your Colfax journey!
