About the Rattlesnake Mountain Challenge

The course runs through the Rattlesnake Mountain and Huffaker Hills trail system, starting with a climb and descent before looping through the lower trails near the trailhead. It is all trail, no pavement, with genuine elevation change on the first section and more rolling ground through the loops at the bottom.

Parking at the Huffaker Hills Trailhead fills quickly. When it does, volunteers direct you to a lot at the Longley Town Center, where a shuttle van runs up to the trailhead throughout the morning. Packet pickup is available the evening before at the trailhead, with a second window on race morning.

Common Questions About the Rattlesnake Mountain Challenge

Will I finish last at the Rattlesnake Mountain Challenge?

Almost certainly not. Half the 5K field finished slower than 44:35, and the last recorded finisher came in around 1:15:34, so there is a long tail of runners behind the middle of the pack. Most fields are far slower than people expect.

Is the Rattlesnake Mountain Challenge a good first 5K?

It is a small race (91 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 Rattlesnake Mountain Challenge?

The 5K winner ran 24:31 while the median finisher took 44:35. That spread points to a mixed field, with a competitive front and a big recreational middle.
