Getting more exercise is the oldest New Year's resolution in the book. (There's no way to fact-check that, but it feels true.) If you've set a goal to get outside and limber up your joints in 2020, there are tons of running events in every distance imaginableā€”from full marathons to half-mile fun runsā€”happening almost every weekend throughout the year. To save you from sorting through the masses, we've rounded up the biggest and most unique ones to know about, from the Susan G. Komen More Than Pink Puget Sound Walk (FKA Race for the Cure) to the Seattle Marathon to Beat the Blerch. See them all below, and find even more options on our complete running calendar.


Run or Wine
This untimed series aims to help you improve your personal 5K goals at your own pace. To add to the lackadaisical nature of the events, each run promises wine (or cider or beer) tastings at the finish line so you can replenish your body old-world style.
Various locations (Woodinville)


Cupid's Undie Run
After a kickoff party with music, drinks, and mingling, lace up your sneakers for a "mile-ish" run followed by a dance party. All proceeds will benefit neurofibromatosis research through the Childrenā€™s Tumor Foundation. Wear your cutest/comfiest underwear.

Love ā€˜Em or Leave ā€˜Em Valentineā€™s Day Dash

Green Lake Park


My Better Half Marathon
These 5K, 10K, and half-marathon runs promise "romance," "kitsch," and "sweat." Here are the categories: "Bromance," "Besties,"Ā "Lovers," and "Lonely Hearts."

Seattle Polar Plunge
If you slept through the various Polar Plunges on New Year's Day, head to West Seattle to dive into the icy waters of the Puget Sound to raise money for Special Olympics Washingtonā€”it's not a race, per say, but we're counting it since you'll likely be running into the water. If you're too scared to jump in, you can keep warm in the "chicken coop" while still raising funds. There'll be beer, food trucks, and live DJs, too.
Alki Beach (West Seattle)


Will Run 4 Beer 5K Series

The change from a Race to a Walk also aligns the fundraising event with the experience of the vast majority of our participants."
