Toshihiko Seko

Toshihiko Seko, born in Kuwana, Mie in 1956, went from Yokkaichi Technical High School to Waseda University and became one of the defining marathon runners of the 1980s — genuinely world-class in an era when the distance was brutally competitive. He represented Japan at the 1984 Los Angeles Olympics and the 1988 Seoul Olympics. I think judging a marathoner by Olympic results alone is unfair to the point of distortion. You can only race the distance a few times a year, a single hot morning can undo eighteen months of preparation, and the weight of national expectation in Japan around the marathon is heavier than in almost any other country. The more telling fact is that he stayed at the top of the world for the better part of a decade. What I find equally worth noting is what came afterwards: he moved into coaching and sports commentary, staying inside the sport rather than leaving it. The second half of that career has now lasted longer than the running did.
