Tokyo will host a one-off international gymnastics tournament next month, organisers said Monday, in what could serve as a practice run ahead of the postponed Olympics. Thirty-two gymnasts from China, Russia, the United States and Japan will face off at the November 8 event -- the first major multinational sporting contest Japan has held since the coronavirus pandemic hit earlier this year. The competition, which has been under discussion for months, will have strict anti-infection measures in place. It is still unclear exactly how the Tokyo Olympics, which were forced back a year by the Covid-19 crisis to July and August 2021, will go ahead.
