2027 Spring Classic Duathlon, Half, 10k & 5k

The Spring Classic opens the Pacific Northwest's racing season on the pancake flats of Vancouver Lake Regional Park, where a duathlon and a half marathon, 10K and 5K all share the same start line. Spring mornings here run from the mid-40s to the low 60s, cool enough to keep you honest and mild enough to race hard after a winter of base miles. The event bills itself as the 42nd edition of a series that has long served as a rust-shedding first test of the year.

The half is road, virtually flat and quick — an out-and-back along Vancouver Lake and the Columbia River on smooth pavement, with no hills to break your rhythm. It's the sort of course that turns a spring goal race into a personal best, and the field stays compact: roughly 245 finishers, with the winner usually home around 1:25.

Why Racing's reputation carries the day, and runners say so plainly — the timing is sharp and the operation is smooth. The finish brings free beer, a finisher's medal and a technical tee. About one in eight come back, a small but steady core that treats the Spring Classic as the season's opening ritual.
