Elevation Profile
This is a very challenging course with 609m of total climbing - well above the average trail marathon - topping out around 68m above sea level. Hill training is essential, and you should expect a slower finish time than on a flat course.
Expected Race Day Weather
Based on historical weather data for February, the expected race day conditions are as follows. Near-ideal running temperatures are expected, ranging from 4°C to 16°C. This temperature range is widely considered optimal for marathon performance, allowing efficient heat dissipation without cold-related issues. There is a low chance of rain (0%), so dry conditions are likely.
Surface Type: Trail
Tokyo Marathon is a trail race, meaning the course includes unpaved surfaces such as dirt, gravel, or forest paths. Trail surfaces are usually slower than the road equivalent - often by 10-20% - because of uneven footing, technical sections, and frequently steeper gradients, though a smooth, non-technical or downhill trail can run faster than that suggests. Trail-specific shoes with good grip are recommended.
