Yokohama Marathon

Launched in 2015, the Yokohama Marathon is one of the newer races on the circuit. Despite its youth, it has quickly built a reputation in Yokohama, attracting runners drawn to its flat roads and scenic routes and the energy of an event still finding its identity.

Runners come to the Yokohama Marathon for one reason: personal bests. The flat, fast course through Yokohama has a reputation as a PB factory, with the roads seemingly designed to keep your pace honest and your splits consistent from start to finish.

With 32,000 finishers and spectators lining the course deep, the Yokohama Marathon generates an atmosphere that carries runners through the hard miles. The crowd support in Yokohama is not polite applause — it's visceral, personal, and often the difference between hitting the wall and breaking through it.

For thousands of runners each year, the Yokohama Marathon is their first marathon. The combination of a forgiving course, generous time limits, and supportive crowds has earned this race a reputation as the place where marathon journeys begin. The first-timer energy on race morning is palpable.
