So Yuki Kawauchi won the Kawauchi Half Marathon in Kawauchi, Japan-

Which raises the question of whether any other runner has won a race that has the same name as the runner, like if Ralph Boston (the old long jumper) won the Boston Marathon or Jack London won the London Marathon.
Has it ever happened before?
Kawauchi already has the record for fastest half marathon in a suit. Maybe he just set another record.
