Carkeek Cooler 5K and 10K Trail Runs

Carkeek Park, Seattle, WA
Join us for a 5k or 10k trail run at Carkeek Cooler, the first event in the 2026-27 Winter Trail Series!

One perk of the Pacific Northwest’s winter drizzle is that places like Carkeek Park are lush and green, brightening up even the grayest of days. Plus, our bountiful water gives us stunning views, such as the sight of the Olympic Mountains across the water from Carkeek’s beach. Most importantly for trail runners, Carkeek is also home to six miles of fun, roller-coaster trails that traverse the forest! The trails range from wide and rolling, to narrow and steep. But if ever you’re feeling like the climb is tough, remember that you get to fly back down!
