Colorado > Redline 13.1 Westminster Half Marathon & 5K Run/Walk
Westminster, CO  •  Saturday, April 5, 2014  •  Course Map

Runners make their way along a gradual downhill on the way out and an equally gradual uphill ascent on the way back in to the finish line at the Redline 13.1 at Westminster Half Marathon, which unfolds along the Big Dry Creek Trail just outside Denver and makes its 3rd annual running in 2013, after its second annual running last year saw more than 180 runners and walkers cross the finish line.

The race starts and finishes -- it follows an out-and-back course -- in the parking lot next to Westminster's RoadRunner Sports running store, which is also the title sponsor for the race.

From there, runners head along paved streets in the first mile and then turn left onto the Big Dry Creek Trail, part of the Denver and Boulder area's running, walking and biking trails system. This trail is made up mostly of gravel surfaces and some paved surfaces, and stretches some 12 miles between Interstate 25 and Standley Lake.

For the Redline 13.1 Westminster race, runners will follow the trail roughly in parallel with the creek, through Westminster's City Park, Westfield Village Park and some residential neighborhoods all the way out to the race turnaround point in Big Dry Creek Park. There, runners will make their way around the edges of the baseball and athletic fields before returning to the trail, and heading back along the route they just ran, all the way back to RoadRunner Sports for the race finish.

Walkers as well as runners are welcome and encouraged in both the half marathon and the 5K, and the scheduled starting times for the race are 7:00 AM for those walking the half marathon and 8:00 AM for those running the half marathon. The 5K Run/Walk is scheduled to start at 9:00 AM.
