The Denver Colfax Marathon is more than a race - it's a tour through the heart of the city πŸŽ¨πŸƒ

Throughout the course, runners are surrounded by colorful murals, public art, and iconic landmarks that showcase Denver's creativity. One of the highlights? The vibrant artwork along the Cherry Creek trail, where every turn brings something new to see.

πŸ’¬ What's your favorite spot along the Colfax course?

Marathon training has a funny way of keeping you humble πŸ˜…

You start the plan expecting every run to feel strong, every workout to go perfectly, and race day to come easily. Then reality hits - early alarms, tired legs, unpredictable weather, missed workouts, and long runs that don't always go as planned.

The good news? That's all part of the journey. Every mile, good or bad, gets you one step closer to the finish line.

πŸ‘‡ What's one marathon training expectation that didn't quite match reality?

The runner chatting with everyone. The one locked into race mode. And the one doing pace math until the last second πŸ˜‚

Which one sounds most like you?

Runner math: every one of these feels like a PR in its own way 🀩

New shoes. Long run done. Finish line in sight. Race morning energy. That β€œI might actually be fast today” feeling.

What’s your #1 running feeling? πŸ‘‡

Two decades of Colfax πŸƒβ€β™€οΈπŸ€—

What started 20 years ago has grown into something bigger than we ever imagined - a community of runners, walkers, volunteers, and supporters who make this race weekend what it is.

We’re so grateful for every single person who has been part of the journey.

And honestly… we’re just getting started. πŸ‘
