Coop's Loop Endurance Run

Coop’s Loop is a 2.1-mile trail loop with 400 feet of gain and descent, designed to test your legs, reward your focus, and keep you coming back for more. The course begins and ends at the Four Seasons Pavilion at the southwest end of Brady’s Run Park. Runners pass through the start gate and immediately hit the defining feature of the loop—a relentless opening climb. Within the first half mile, you’ll ascend from roughly 860 feet to 1,100 feet, with sections reaching a steep 24.6% grade. It’s a leg burner right out of the gate and sets the tone for the lap. At the top, a clearly marked left turn leads you onto one of the best ridgeline single-track sections in the park. This stretch offers a brief opportunity to settle in before the second climb hits. After a quick downhill, the trail pitches back up again—shorter than the first climb, but comparable in intensity—bringing you to the high point of the course at approximately 1,150 feet. From there, another marked left sends you into a flowing descent down well-established switchbacks. The trail is smooth, intuitive, and fast, winding through a scenic hemlock forest that defines this section of the park. Around the one-mile mark, the course transitions into predominantly downhill terrain. Runners continue descending on single track, passing competitors grinding their way up the second climb—adding a unique, interactive energy to the loop format. The trail eventually connects to a service road, guiding you back toward the start/finish. As you approach the pavilion, you’ll take a right over a small bridge, pass through the central aid station, and re-enter the start/finish chute—where the next lap begins.
