03 / Course & training
A course built to tell a story
Tokyo's route was deliberately designed to move through the city's past, present, and future. It starts near the futuristic skyscrapers of Shinjuku, passes through the electronics district of Akihabara, runs by the historic Sensoji Temple in Asakusa, and finishes in Marunouchi, the modern business district near the Imperial Palace and Tokyo Station. A 2017 to 2018 course revision made the layout flatter and genuinely record-eligible, and it has produced fast times ever since despite typically cold, early-March conditions.
Famous winners and defining moments
Tadese Takele won the 2026 edition in a tactical sprint finish, 2:03:37, ahead of Geoffrey Toroitich and Alexander Mutiso Munyao, his second consecutive Tokyo title. Only one other man, Birhanu Legese in 2019 and 2020, has ever repeated as Tokyo champion, which places Takele's back-to-back win among the race's rarest achievements. On the women's side, Brigid Kosgei ran 2:14:29 in the same 2026 edition, a new course record, a minute faster than the previous mark. Marcel Hug and Catherine Debrunner won the wheelchair races.
Tokyo's reputation is built as much on scarcity as on speed. With acceptance rates typically in the single digits to low double digits, simply being selected to run is, for most applicants, a longer process than training for the race itself.

How to train for Tokyo
Tokyo asks less of your legs than a hilly course like Boston or New York, and more of your preparation for cold weather and travel.
Rehearse your cold-weather race morning
Early March in Tokyo is typically cold. Practice your warm-up and start-corral routine in genuinely cold training conditions beforehand, including a layering plan you can shed easily, so race morning is not the first time you have managed the cold before a hard effort.
Train for sustained goal-pace endurance
Like Berlin and Chicago, Tokyo's flat profile rewards even, disciplined pacing more than hill strength. Marathon-pace tempo runs and controlled long runs matter more here than terrain-specific work.
Plan for travel and jet lag if you're coming from far away
International runners, especially from Europe or the Americas, are covering serious distance to get here. Build in extra days to adjust your sleep schedule before race day, rather than arriving and racing on a body that thinks it is a different time zone entirely.
Cold-weather and travel logistics matter, but they sit on top of real fitness, not instead of it. Build your aerobic base and anchor your week around the long run well before race week.
