Trail Running in Seattle

Destination Dirt: Seattle, Washington provides Seattle-area trail running resources for new and experienced trail runners alike.

By on August 7, 2012 | Comments

Nestled between the Cascade Mountains to the east, the Olympic Mountains to the west, and more sparkling bodies of water than you can count, Seattle is a city of breathtaking beauty. It’s no surprise that outdoor enthusiasts flock en masse to this Pacific Northwest paradise.

Seattle Trail Running

While the sky can be a bit of a perpetual leaky faucet, the good news is that Seattle boasts some of the mildest year-round weather to be had, with temperatures ranging from 45 to 70 degrees Fahrenheit for the majority of the year. Trail systems within or near the city generally remain snow-free and runnable year-round. In the summer, an expansive menu of rugged, mountainous trails nearby becomes available as well to those hungry for more vertical gain, technical terrain, and arresting views.

Seattle’s city planners have had a strong, long-standing passion for green spaces. While the region’s most expansive trail networks lies outside the city, there are still plenty of ways to get your dirt fix without leaving city limits. One of the best ways to explore the city’s trails is to get your hands on a bike map, and seek out the green areas.

Discovery Park

This 534-acre wild park is just a few miles from the city center, perched on the bluffs of Magnolia overlooking Puget Sound. Featuring forested singletrack, sandy beaches, bluff trails, tide pools, spectacular views of the Olympic Mountains and Mount Rainier, and frequent bald eagle sightings, it’s the most outdoors you can soak up without leaving Seattle proper.

The 3-mile Loop Trail is well signed for an easy, beautiful tour of Discovery – but offshoots like the Hidden Valley Trail and North Beach Trail reward those who venture off the beaten path.

Washington Park Arboretum

Along the shores of Lake Washington, the 230-acre Washington Park Arboretum will dazzle you on your run with a fantastic array of trees, plants, colors and smells. With forgiving, soft gravel trails that snake all over the park, the possibilities are endless.

For a truly unique run on one of the city’s best kept secret trails, venture to Foster Island at the north end of the park, and run the boardwalk bridges to Marsh Island. Chances of bald eagle sightings are high here, as well!

Insider Tip: During the summer, you can rent a canoe for $5 at the University of Washington’s Waterfront Activity Center and paddle your way around the Arboretum, too.

Greenlake/Woodland Park

With an easy, beautiful 5K loop around the lake – side by side paved and dirt surfaces – this area is often touted as the “runners’ paradise” of Seattle. Nestled north of downtown and surrounded by many of the city’s top specialty running shops, bike shops and gyms, it’s a popular destination for the active-minded.

Greenlake plays host to the annual spring Dizzy Daze ultra. Boasting distances ranging from half-marathon to 100K, the race’s motto teases the running junkies to which it sells out each year: “All the pain and suffering of an ultra, without the annoying change of scenery!”

While the pancake-flat Greenlake gets crowded when the weather’s nice, the adjacent Woodland Park – sandwiched between the lake and the Seattle zoo – features a hidden network of short, albeit hilly and under-utilized, trails.

One tucked away gem of a trail in Woodland Park runs alongside the zoo’s elephant pasture and orangutan house. Free whiffs of nature!

Issaquah Alps

For the most insatiable of trail appetites, venture a dozen miles east on I-90 and you’ll hit what are affectionately known as the Issaquah Alps – a term coined by the late nature author and local conservationist, Harvey Manning. The Alps include the popular Cougar, Squak, Tiger, Taylor and Rattlesnake Mountains, and encompass thousands of acres of old-growth and second-growth forest. Their singletrack trails offer everything from gentle loops to challenging climbs with sweeping views of the surrounding valleys.

Of these mountains, Cougar is the best mapped, well-signed, and easiest to navigate, if you’re not already familiar with these trails. And near as they are to urban areas, the Alps are bear and cougar country – so always try to run or hike with a buddy.
