Ralston Creek Half Marathon & 5k
Race Information
The Ralston Creek Half Marathon and 5K follow a mix of roads and bike paths on the west side of Arvada. The 5K is mostly flat and fast, with a small rise in the final mile. The opening four miles of the half-marathon are fairly flat, with a barely noticeable gradual gain in elevation. Miles 4 - 6.5 are rolling, with one good climb leading to the high point of the course atop Ralston Mesa. From there, the course is almost all downhill and flat to the finish, and aid stations are available every two miles. Finisher’s medals for all Half Marathon finishers. Prize money offered.
