Marathon races near Yokohama

Yokohama Bay Miles

Yokohama hosts 70 Marathon races in 2026 within 80 km of the city centre — upcoming dates, recurring series, and other races nearby, all in one place.

Locals stack easy Z2 along the Minato Mirai waterfront, then add loops through Yamashita Park, Osanbashi Pier, and Nissan Stadium when they want rhythm without fuss. The Tsurumi River path gives long-run room because it goes over 21 km to the Onda River. The bay side has 3 km of paths when you want that option. Negishi Forest Park has a 5 km circuit around grassy fields and orchards. YOKOHAMA Minato-Mirai Running Club runs every Thursday at 19:10 from the bathhouse near Ishikawa-Cho JR, and Tokyo Legacy Half Marathon or Tsukuba Marathon can anchor the calendar.

Locals ride the flat bay course when they want spins, stops, and coffee legs through Chinatown, Yokohama Park, Zou no Hana Park, Aka-renga Park, CUPNOODLES MUSEUM Park, and Bashamichi. The loop is 3 km, so it works more like a shakeout than a gran fondo. Tokyo Cycling Club is the obvious place to look when a road rider near Bashamichi wants group rides or bikepacking trips. Kamakura Daihatsu gives the first proper bite because the route runs 26 km and climbs 345 m. The climb is 9 km into 1,208 m of ascent. World Triathlon Championship Series - Yokohama is the local anchor event.

May feels like the cleanest training month, and August still pulls cyclists out even when the air sits hot and heavy. Locals run early in the morning because summer heat and humidity can turn normal intervals into survival pace. The city centre stays useful in summer because Minato Mirai, Yamashita Park, and the Tsurumi River keep flat options close. Winter changes the kit, not the habit. Winters are chilly, but the city is surprisingly sunny, and frosts are not frequent. Runners keep tempo work on the bayfront, and riders use sunny days for base miles before saving the bigger climbs for warmer windows.
