Cycling & running events in Takamatsu, 2026

Takamatsu Coastal Training Notes

Running: Locals run Takamatsu like a coastal base, with easy loops on the Takamatsu Plain and small bumps when they want work. The 40 km shakeout with +7 m suits Z2 days before intervals. The 31 km route with +93 m gets used when flat legs need a sting. The 32 km route gains +72 m and feels right for steady base miles. The brief lists no named run club, so repeat routes do the grouping. Okayama Marathon gives the calendar an anchor event.

Cycling: Locals ride for sea, rivers, and short climbs in the same outing. Prefectural Route 150 sits by the Seto Inland Sea, and locals link it with Prefectural Route 36 around the Aji Peninsula when they want coastal base miles. 5 m. The climb is 3 km and gains 202 m. Yashima gives the northeast a clear climb target. The brief lists no named cycling club, crit, gran fondo, or cyclocross anchor.

Season: May to September is the main training block, and locals respect it because the same months bring the heaviest rain. Summer brings hot, humid days, so runners keep harder intervals tidy and riders push Z2 early along the sea. The Seto Inland Sea gives blue sky and ocean as far as you can see when the weather opens. Winter turns cool, and both sports get more measured. Runners stay on the Takamatsu Plain for rhythm, while cyclists use Prefectural Route 150, Prefectural Route 36, and the Koto River side when the legs want steady work.
