Seattle, United States of America · Saturday 28 November 2026
This race appeals to runners chasing a fast time or looking to build confidence on a straightforward course. The completely flat terrain means you won't waste energy fighting hills, which is ideal if you're aiming for a personal best or training for a more demanding marathon later. It also suits people who simply want to enjoy the experience without the mental burden of climbing. That said, flatness can feel monotonous for some runners, and the lack of elevation changes means your legs take a pounding for the full 42.2 kilometers without any recovery sections where you can ease off the pace. First-time marathoners will appreciate the predictable effort required, though more experienced runners might find the course less interesting tactically. On the day, expect to spend over four hours running through Seattle's streets and neighborhoods, moving between lower elevation zones that hover around sea level. The flat profile means your GPS watch won't show dramatic elevation changes, but this also means the course won't offer natural aid stations at valley points or the psychological boost of downhill sections. Urban marathons bring their own challenges: road surfaces vary, you'll navigate turns and potentially traffic patterns, and there's less shade than trail alternatives. November weather in Seattle is cool and often wet, so you could face rain at any point, which on a flat course means you're just running through it rather than descending past it. Fueling and pacing become particularly crucial on a run like this, since you can't rely on gravity to give your quads a break.
