About the Cougar Mountain Trail Run Series (August)

Cougar Mountain is a proper trail run in the hills east of downtown Bellevue, put on by Seattle Running Club. The course runs through forested park land with enough elevation to make the longer options feel like a real mountain effort. Distance choices range from a short loop to a full marathon, so you can pick something that matches where your training is right now.

Post-race, Flying Lion Brewery supplies beer, and there is food waiting at the finish. A portion of every entry goes directly to King County Parks, which maintains the trails you just ran on. Day-of registration is available if you miss the online window, which closes a few days before each event.

Common Questions About the Cougar Mountain Trail Run Series (August)

Will I finish last at the Cougar Mountain Trail Run Series (August)?

Almost certainly not. Half the 3.1 Miles field finished slower than 35:18, and the last recorded finisher came in around 1:19:39, so there is a long tail of runners behind the middle of the pack. Most fields are far slower than people expect.

Is the Cougar Mountain Trail Run Series (August) a good first 3.1 Miles?

It is a small race (111 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 3.1 Miles, that spread matters more than the winner's time.

How competitive is the Cougar Mountain Trail Run Series (August)?

The 3.1 Miles winner ran 21:59 while the median finisher took 35:18. That spread points to a mixed field, with a competitive front and a big recreational middle.
