To ensure accuracy, course distance measurements were taken with World Athletics and the Japan Association of Athletics Federations.
On Saturday 10 and Sunday 11 October 2020, approximately 100 participants, including one measurer from World Athletics (WA) and three measurers from the Japan Association of Athletics Federations (JAAF), took part in the measurement of the Olympic Marathon and Race Walk course in Sapporo, Hokkaido.
With safety precautions in place and vehicles clearing the path, WA course measurer David Katz and JAAF measurers rode calibrated bicycles to measure the marathon course from midnight to dawn on Saturday, 10 October. Early Sunday morning on the 11th, the same method was used to measure the race walk course.
Going forward, as the necessary procedures are completed and certified by WA and the JAAF, the 42.195km marathon and 20km/50km race walk course will be officially confirmed. Once approved, the certification by WA and the JAAF will be valid for five years, leaving a standing legacy course that can be used for various future events after the Tokyo 2020 Games.
Accelerating preparations for the Games in 2021
In addition to David Katz, Jakob Larsen, World Athletics Director of Competition and Events, and Technical Delegate Luis Saladie also arrived in Japan.
Larsen said: "I once again witnessed the high level at which preparations are being undertaken. Having completed course measurements, we would like to establish several points and further accelerate preparations."
With the cooperation of WA, the JAAF, and all of the venues involved, the course was successfully measured in October before snowfall.
Tokyo 2020 will continue ongoing efforts to organise a safe and secure event for athletes and spectators in order to hold the Games in 2021.
