Half Marathon races near Kawasaki

Kawasaki Training Notes

Kawasaki hosts 48 Half Marathon races in 2026 within 80 km of the city centre — upcoming dates, recurring series, and other races nearby, all in one place.

Locals run Kawasaki like a dense urban base-mile town. The 13 km with +98 m route works when you want steady work. The 14 km with +77 m route feels right for longer Z2. The 10 km with +52 m route works when flat legs need a little bite. Tokyo Legacy Half Marathon and Tsukuba Marathon sit as clean anchor races, and the 2027 Tokyo Marathon Semper Fi & America's Fund Team is another target.

Locals ride Kawasaki because the city gives options fast. Bikemap lists 701 cycle routes here, so base miles never feel hard to plan. The route runs 6 km with 196 m ascent for longer steady days. 大師サイクリングクラブ keeps the local side rooted in Kawasaki, while ヨコハマサイクリングクラブ and ヨコスカサイクリングクラブ keep touring legs honest. The west holds the climbs.

May and June are the best months, and locals tend to get on the bike most then. Summer has no clean specifics in the brief, so locals keep the plan simple and use the same riverbanks, urban flats, and Z2 loops without pretending the data says more. Winter also has no clean specifics in the brief, so runners and riders shift by feel rather than by a named local rule. South and east Kawasaki stay flat, urban, and coastal, while the west keeps the hilly option open for intervals, hill reps, or a harder gran fondo block.
