The Tokyo Olympics were scheduled to open last week before the pandemic pushed them back to next year. Australian Olympic Swimming champion Mack Horton would’ve been racing this week, defending his 400m Gold medal from Rio. It would also have been the first Olympics without a Sun Yang drug cloud hanging over it after the Chinese swimmer was banned for eight years after tampering with a drug test. He joins us on today's show as our very special guest.
