Sapporo Half Marathon
First held in 1958, the race began as a full marathon competition for men under the moniker of the Hokkai Times Marathon. This lasted until 1973, as it was replaced with a shorter race of 30 km in 1974 and became known as the Times 30K. A women's programme was introduced in 1981, at which point the men's 30 km race was complemented with a women's 20 km. The women's race was slightly extend to the half marathon distance in 1986 and the men's race followed suit the following year. The road racing competition was known as the Sapporo Half Marathon from 1990 onwards.
