Overview

The Marathon Festival series comes to Showa Kinen Park in Tachikawa in mid-January, with JAAF-certified races over 30km, half marathon and 10km alongside a 5km and two 1km parent and child events. Every distance runs on the same 5km loop inside the park, so the 30km works out at six laps and the half marathon runs four laps plus a short closing section. The start and finish share the ginkgo tree-lined avenue beside the Undo Hiroba sports plaza, where race number collection opens on the morning. Both JAAF-registered athletes and general runners are welcome, and runners in the registered division receive certified times. Aid service appears every 2.5km, split times are recorded every 5km, and pacemakers are planned for the longer races.
