Run the Tsukuba Marathon on Nov 22, 2026: a famously flat, fast Ibaraki PB course on the start/finish layout renovated in 2025. First-come entry, 6-hour limit.
Running the pancake-flat Tsukuba course in late November means crisp, dry air and golden ginkgo-lined streets, a perfect setting for a steady 42k. Afterward, warm up with a bowl of hearty miso tsukemen in the science city, or stroll the JAXA Space Center's exhibits to reflect on how far you've come.
Event Details
60m
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.
