Course Map & Elevation
Course Overview
A fast, predominantly flat point-to-point course that drops from 55m at Shinjuku to 29m at Tokyo Station, with ~135m of total climbing spread across rolling undulations — more than the 'flat' label suggests. The one thing that makes Tokyo unique is the early-March timing combined with impeccable Japanese race organization — aid stations run like clockwork, and the crowd support is respectful but relentless, lining every metre of the course.
Key Segments
Shinjuku to Nihonbashi
Terrain: Net downhill from 55m to 23m, with a sharp initial drop and a climb back to 52m at km 2, then descending through wide Tokyo boulevards past the Imperial Palace
Challenge: The gentle downhill and electric atmosphere of 38,000 runners streaming through Shinjuku tempts aggressive early pacing
Tactic: Run 5-10 sec/km slower than goal pace. The descent is subtle but real — save your quads. Enjoy Iidabashi and Kanda but stay controlled.
Asakusa Loop and Ryogoku
Terrain: Flat, with a brief rise (~3m) crossing the Sumida River bridges. Out-and-back through Asakusa then south through Ryogoku
Challenge: The Asakusa turnaround creates congestion and the Senso-ji Temple atmosphere pulls attention away from pace
Tactic: Settle into goal pace. The Asakusa loop is the most scenic stretch — soak it in but keep rhythm. Take gel by km 18-20.
Ginza to Shinagawa Turnaround
Terrain: Flat through Ginza, then an out-and-back along the waterfront to Shinagawa. Minor bridge undulations.
Challenge: The Shinagawa turnaround (km 30) is mentally deflating — you run 5km south only to turn and come back. Wind exposure along Tokyo Bay can be significant.
Tactic: This is the grind section. Use the Ginza crowd energy at km 25, then hunker down through the waterfront. Tuck behind a pace group if headwinds hit along the bay.
Toyosu to Tokyo Station
Terrain: Flat waterfront running through Toyosu, then back to the Imperial Palace area and Tokyo Station
Challenge: Wind exposure along Toyosu waterfront. The final 3km approach to Tokyo Station can feel long when fatigued.
Tactic: If you ran patiently, this is where you cash in. The crowd builds as you approach central Tokyo. The wide boulevard to Tokyo Station is your victory lap — maintain form and push.
Race-Specific Training
- •Practice running in cool-to-cold conditions (5-10C) with layers you can discard — Tokyo's early March start can be chilly with rapid warming
- •Include waterfront or exposed-route long runs to prepare for the wind along Tokyo Bay between km 28-35
- •Train for mental toughness through out-and-back courses — the Asakusa and Shinagawa turnarounds require the discipline to stay patient when you reverse direction
Conditions & Environment
Altitude
Start at 55m, finish at 29m. No altitude concerns. Net downhill of 26m with ~135m total climbing.
Weather
Early March. Typical race-morning temps 5-12C (41-54F). Can occasionally dip to 2-3C (36-37F) at the start. Rain is possible — March is transitional in Tokyo.
Sun & Wind
Bay winds along the Shinagawa and Toyosu waterfront (km 28-36) can be strong and cold. Morning sun is low on east-facing stretches. Urban canyon sections through Ginza provide wind shelter.
What to Wear
Arm sleeves are ideal for the cool start — discard by km 10 as you warm up. Gloves for colder years. A disposable poncho for the start corral if rain is forecast.
Pacing Strategy
| Segment | Pace | Note |
|---|---|---|
| km 0-10 | 5-10 sec/km slower than goal pace | Gentle downhill, big crowds. Bank energy on the descent. Resist the Shinjuku surge. |
| km 10-22 | Goal pace | Flat terrain through Asakusa and Ryogoku. Lock in rhythm. Take gel at km 18-20. |
| km 22-35 | Goal pace | The working section. Ginza to Shinagawa and back. Expect wind. Stay focused through the turnaround. |
| km 35-42.195 | Goal pace or faster | The payoff for patience. Flat approach to Tokyo Station. The crowd crescendo will carry you. |
Race Day Tip
Tokyo's race organization is world-class but the logistics are strict. You must be in your corral by the stated cutoff time or you will not start. The subway to Shinjuku on race morning is packed — arrive 2+ hours early. Also, Japanese aid stations offer unique items like rice balls and miso soup at later stations — these can be a lifesaver if you are bonking, but practice eating solid food on the run beforehand.
