About the All-Out Fall Fest

The course runs out and back along Big Dry Creek Trail, heading toward Standley Lake Regional Park. The surface is mostly concrete and pavement with some softer gravel once you get deeper into the park. Somewhere along the way the lake opens up with the Flatirons sitting on the horizon behind it. Aid stations and portable toilets are spaced along the route.

Early packet pickup happens the evening before at a local running store in Westminster. On race morning, pickup opens well before the first wave goes off, but it closes tight before each distance starts, so arriving early matters. The start is out of an office park parking lot, which keeps logistics simple.

Common Questions About the All-Out Fall Fest

Will I finish last at the All-Out Fall Fest?

Almost certainly not. Half the 5K field finished slower than 35:43, and the last recorded finisher came in around 1:05:24, so there is a long tail of runners behind the middle of the pack. Most fields are far slower than people expect.

Is the All-Out Fall Fest a good first 5K?

It is a small race (137 finishers), which is friendlier and less intimidating than a big-city event, though the field thins out. There is no qualifying time, and the finish-time spread above shows how varied the field really is. If it is your first 5K, that spread matters more than the winner's time.

How competitive is the All-Out Fall Fest?

The 5K winner ran 20:51 while the median finisher took 35:43. That spread points to a mixed field, with a competitive front and a big recreational middle.
