Which distances should I choose?
You have four options: a 1 Mile Fun Run, 5K, 10K, and a Half Marathon. Because the event uses a wave system (7:30 AM, 8:00 AM, and 8:30 AM), the Half Marathon is your best bet if you want to actually feel like you're "racing" while still maintaining a chill pace. The 5K and 10K are perfect for those who want to finish early and spend the rest of the Saturday exploring the city.
What is the terrain like on the route?
The course is set within Lincoln Park, which means you'll be running on paved paths and park trails. Expect some gentle rolling sections—Seattle isn't flat, even in a park—but it isn't a technical trail race that will trip you up. You'll get those classic Pacific Northwest waterfront views, which makes the effort feel much easier than the elevation profile might suggest.
What should I expect to wear for the weather?
June in Seattle is beautiful but unpredictable. Expect temperatures in the mid-60s to low 70s (18-22°C) at the 7:30 AM start, but don't be surprised if a marine layer rolls in and makes it feel crisp. A light moisture-wicking layer is smart for the start, but you'll likely want to strip down to a singlet once you're moving.
How much am I going to pay to run?
The pricing is quite fair for the Seattle area, especially given the "eco option" if you don't care about the swag.
- →5K: $49
- →10K: $55
- →Half Marathon: $65
- →Virtual: $37
- →Eco (no shirt): $30
Note that registration closes on June 19, 2026, at 10:00 PM PDT.
What do I get for finishing?
You'll walk away with a finisher medal and either a finisher towel or a specific giveaway. If you pay the full registration fee, you also get a running T-shirt (shipped within the US). If you're looking for official timing data, keep in mind this isn't a traditional chip-timed race; you'll need to track yourself via an app, though you can check Thebestraces ↗ for online results and certificates.
