大通公園
Odori Park is the traditional venue of Hokkaido Marathon. From 2012 edition of the race, the start of the race was moved from Nakajima Park to Odori Park. Sapporo, which hosted the 1972 Winter Olympics, lies 800 km from Tokyo, but was named as the venue for the Olympic marathons and racewalking in October 2019. This decision, taken before COVID-19 crisis, was made due to fears about high temperatures in Tokyo. Odori Park will be the start and the arrival for both marathons. Its route features a large loop which is about the length of a half-marathon (20 km), followed by a second smaller loop (10 km) which will be completed twice.
