Event Description

The Ralston Creek Half Marathon and 5K returns in 2022, after a hiatus in 2021 due to the COVID 19 virus!

The Ralston Creek races feature a fun winter half-marathon and 5K run conveniently located on the west side of the Denver Metro Area in Arvada, Colorado. The courses cover a scenic mix of road and bike path over rolling terrain, and an optional early start time for half-marathon runners who expect to take more than 2 hours 45 minutes to complete the course!

Half-Marathon entry is limited to the first 650 registrations. 5K registration is limited to the first 350 entries. Once a distance has filled, we cannot accept any additional entries for that distance.

Your entry fee includes entry into the race, a finisher's medal (for half-marathon runners who complete the course), FREE race photo downloads, fun music, hot cocoa and tasty breakfast burritos, and if you are one of the speedy guys or gals up front in the half-marathon, you may take home a bit of cash!!!

A long sleeve tech shirt will be included with all adult entries. Youth 5k entries will include a short sleeve 50/50 t-shirt.
