Olympics: Athletics, Day 9

Karsten Warholm pulverised the world record when he won the 400 metres hurdles title at the Tokyo Olympics, but whether he is in that sort of form is open to question. His perennial bridesmaid Rai Benjamin will pray he is not. The United States track and field team is having a terrific Games and will be looking to sweep both 4x100m relays. The never dull Sifan Hassan -- small of stature but big of heart and courage -- runs in the 10,000 metres less than 48 hours before the Dutch star tackles the marathon.
