2026 Tsukuba Marathon - Nov 22

Loop-style road marathon on a flat, certified course marathon course in Tsukuba with 60m elevation gain. A pancake-flat course across the Tsukuba science-city plain with negligible elevation change, long straight stretches and only a handful of gentle rises — built for even pacing and personal bests. The start/finish was reconfigured around iias Tsukuba and the city hall in 2025, so 2026 is the second running on the renovated layout
