Trail Running in Seattle

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.

Seattle Trail Running - Greenlake

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.

      scott i guessing you're only being 50% serious(or maybe 0%). but if you are serious wouldn't you rather those folks be on the trails than on their couches? or in their cars? or causing trouble somewhere? i feel like the more folks on the trails the better!!! if we get "too many" on the trails we currently have then by golly we'll just have to build more trails. and if we run out space for new trails then dang it we'll just have to take over the legislature and demand more public space for recreation and wilderness and less for shopping malls and clearcuts!

        I would hope he is 0% serious. I agree, I would LOVE more people to get out of their house and run. I have such a tough time talking to anyone outside of my running buddies because I know NOTHING about the X Factor or the latest movies.

        The more people that get out on these trails the better. We have more advocates, more like minded people and we grow the discourse in protecting our natural places :)

        On the other hand, I can sometimes be a trail snob especially coming out of the Gorge from a 4-5 hour run into the throngs of tourists. But the way around that is to start early and get your miles in outside of the 2 mile radius from a road! :)

        BTW, James Varner puts on the BEST trail races!

          I would prefer more trail runners come rather than any other douchebag-types that migrate here. You heard it from a Seattleite.

    2. Andy

      Even if he's 100% serious, it's understandable that Scot, like many of us, savor the peace and relative isolation the trails offer. But, seriously, who really thinks this posting on iRunFar is going to attract that many more people to the trails in and around Seattle? Preaching to the converted is pretty low risk.

    Nice writeup! While I don't miss the endless gray drizzle of winter, I do miss the ability to run year round in (usually) predictable conditions. I first "discovered" ultrarunning through the great folks at Seattle Running Co (now Fleet Feet) during my 4 year college stint in Seattle, and it has become a large part of who I am.

    I can't count how many laps of Greenlake and Woodland Park I ran while I lived there…

      Ken,

      You're right; the trail running community here is fantastic. Not sure we properly met at Pigtails, but I was out there volunteering at the far aid station and then pacing for George O. for his final laps…Anyway, just wanted to say that your grinning, cheerful self was (and continues to be!) quite the talk of the town among "the awesome community of crazy runners" up here :) You are welcome in Washington ANY TIME! Thanks for spreading your awesome passion for this great sport.

      – Yitka

    always looking for a good excuse for a get-away…this article fits the bill

    with great run opportunities..thanks for sharing!!!

  3. Jeff

    Seattle's certainly a suitable alternative for those poor souls who aren't fortunate enough to enjoy the hundred plus miles of sunny, uncrowded single track that Boise has to offer. ;) I jest, of course. Nice intro.

  4. Matt P

    Switchbacks.com is a great resource. Go to "static maps" and there are several .pdfs of various trail networks, including Cougar, Tiger, Squak, Rattlensnake, Mt. Si/Tennerife.

    Well written!

    Seattle is a runners play ground! One Weekend we had a hotel in downtown and decided to run a loop of farmers markets around the city! We connected all the green space we could in our 20+ mile route and had a blast eating our way around neighborhood to neighbourhood. And,people are so darn nice there!!!!

  6. Stevie Ray

    Thanks for the headline-catcher pic of Myrtle Edwards park, where I run almost every single day. It's not even mentioned in the writeup though :-). Luckily, the separate paved bike trail will open again RealSoonNow and the bikers and runners will again live in peace.

    In addition to the city stuff and the Issaquah Alps stuff, Seattle is a nice hub for hardcore diversions down south (Mt Rainier and Mt St Helens) and up north (Chuckanut and BC).

    Plus you can run with me and I will buy you a soda.

    Thanks for this resource. I’ll be up there Memorial Day weekend and am looking for two trail runs to get as much of the Seattle/PNW experience as possible. Want to help me plan? I’m looking for one in the 20 – 25 mile range… I’ll rent a car and would be interested in doing something out in/by Olympic NP or around Mt Rainier if there are (mostly) snow-free options this time of year. The other run will be more more like 10 miles and I’ll need to be able to get there without a car. Maybe Cougar Mountain, but something within the city could be really cool. Any thoughts? Thanks so much!
