The Story

There's something about triathlon in Seattle that doesn't translate to photos. The 1500m swim sends you into cold freshwater lake at 15°C — bracing — the kind of cold that sharpens focus. The 40km bike packs 426m of elevation gain — a seriously hilly course that separates climbers from time-triallists. A 10km rolling run through Seattle that punishes anyone who left their legs on the bike. What makes it memorable: Puget Sound chill, Mount Rainier appearing through clouds, spectators in Gore-Tex. Not the longest day in triathlon, but one that leaves a mark.

"You don't come to Seattle for a fast time. You come for the experience — and then you surprise yourself."

What It Feels Like

A olympic course that reflects Seattle: Emerald City drizzle and determination. It suits experienced athletes who want terrain to match their training. This course rewards preparation and punishes overconfidence. Race it once and you'll understand why people return.

🏊 The Swim

A 1500m freshwater lake swim at 15°C. No salt sting, no currents, just you and the distance. Lake swims reward smooth technique over brute force.

🚴 The Bike

40km with 426m of climbing — a seriously hilly course that rewards power-to-weight over pure wattage. The climbs are the race; the descents are recovery. Come with climbing legs or come with patience.

🏃 The Run

10km of rolling Seattle terrain. Just when you find a rhythm, the road tilts again. In cool 14°C conditions, the rollers add a cumulative cost that flat-course runners don't expect.
