Kōsei Miura

Ninety-one wins in his debut year, breaking a rookie record held by Yutaka Take, the most famous rider in the country: that is the kind of start that decides how the rest of a career gets discussed. Kosei Miura was labeled the next big thing while still a teenager, and I have always been more curious about what that label costs than about the record itself. Born in Tokyo in 1989 and standing 167 cm, he has spent his adult life steering half-ton animals at full gallop, with a long absence for serious injury somewhere in the middle. The hard part of a career like his is not the fast start; it is the decade after the attention moves on to the next prodigy. He is still in the saddle. That, to me, is the real achievement.
