Tokyo Marathon Guide
The Tokyo Marathon is a flat, fast, superbly organised road marathon held in early March. Cool late-winter weather and a smooth course make it a strong personal-best venue. With few hills and excellent crowd support, the main pacing task is patience through the busy start and even effort thereafter.
- Location
- Tokyo, Japan
- Distance
- Marathon (42.2 km / 26.2 mi)
Typical conditions
Held in early March. Cool (around 5–12°C), occasionally with a cold wind. Layer for the wait at the start, then race light.
Course & elevation
- Flat and fast through central Tokyo with smooth roads and a few gentle undulations.
- A handful of out-and-back sections and turns, but nothing that disrupts rhythm for long.
- Strong, orderly crowd support and excellent on-course organisation.
Pacing strategy
- The flat profile favours even splits — settle into goal pace early and hold it.
- Be patient through the crowded opening kilometres rather than surging to find space.
- Cool conditions help, but dress to race warm; you will heat up quickly once moving.
