Thanks for another great year!

The ACR is Colorado’s premier half marathon.

Held each year on the third weekend in September as the aspen leaves are changing from green to gold. 

Some of the things that make the Autumn Color Run great:

Every race course has an amazing view!
Awesome after race party at the finish line that includes pasta & salad bar, home baked goodies, live music, and a bottle of water as you cross the finish line.
Well stocked Runner Gift Bag and Race T-Shirt.
Free pre-race YOGA in the park.
All Half Marathon finishers get a medal!
All fun runners get a ribbon.

The Runner T-Shirts are a super soft poly/cotton blend.

Both shirts are gender specific cuts. Please choose your size carefully!
No exchanges on shirts until after everyone has checked in:)
