Run the flat Kasumigaura Marathon by Japan's second-largest lake near Tokyo. First-come entry, 6-hour limit, co-staged with the International Blind Marathon.

Why attend here

Lake Kasumigaura’s flat, scenic loop makes for a fast, meditative run, with the gentle rise early on and the lake’s calm waters guiding you home. April here is mild and pleasant, perfect for a post-race stroll along the waterfront or a visit to Tsuchiura’s historic castle ruins. Refuel with local hits like the region’s freshwater eel or a warm bowl of soba, and enjoy the quiet, unhurried pace of spring in this lakeside town.

Course

A famously flat course that loops around Lake Kasumigaura. The first half crosses an elevated plateau with the only real climb (a gentle rise of about 20 m starting near the 2 km mark), then the second half runs alongside the lake on flat ground.
