Suguru Osako

A marathon in the 2:04 range still reads like a typo to me. Suguru Osako, born in Machida, Tokyo in 1991 and standing 170 cm, is not built to overpower anybody; he simply refuses to slow down. He took the 10,000 m gold at the 2011 Summer Universiade in Shenzhen, holds the Asian junior record in the half marathon, and rewrote the Japanese marathon record himself, running 2:04:55 for fourth place at the 2025 Valencia Marathon. What I respect most is that he never settled into the comfortable, well-funded system waiting for him at home. He kept choosing his own base, his own training, his own terms, which is a lonelier way to build a career than it sounds. He has stepped away from the sport and then come back to it, and that tells me running isn't a job to him so much as the way he checks whether he's still himself.
