Crested Butte is known for having some of the best trails in the country. Runners will be challenged by this high altitude course. Its wide open views will amaze runners, as they traverse through Gunnison National Forest.  There will be wildflowers and the beginning of fall will bring the changing aspen leaves. The event will start and finish at the Crested Butte Community School.

Aid Station and Cut Off Information

That's right! We have gone cupless!

​​​

What does that mean?

• Hands free water dispensers will be located at the start/finish line and at every aid station.

  • Runners can use these to fill bladders, bottles​

• Gloved volunteers will pour sodas/misc drinks into runners' reusable cups.

• To further reduce waste at aid stations, runners may bring a small reusable bag or bowl for food to be served into.

  • Reusable bowls are optional but a great way to reduce waste.
