Ikee to concentrate on relay at Tokyo Olympics Today 06:00 am JST Today | 06:53 am JST TOKYO Leukemia survivor Rikako Ikee will concentrate on the relays at the Tokyo Games this summer, with the Japan Swimming Federation naming her Monday on its entry list for the Olympics. The 20-year-old, who was diagnosed with leukemia in February 2019, stunned the swimming world this April by winning all four of her events at the national championships -- the 50- and 100-meter butterfly and freestyle -- to earn spots on two Olympic relay teams. She is set to swim her first race of the Olympics in the 4x100 freestyle heats scheduled for July 24, a day after the opening ceremony.
