For all the joy, disappointment, anger and disbelief, it's worth remembering that there is life outside competition.
Aries Merritt, who won a bronze in the 110m hurdle on Friday, spoke earlier to Gabby Logan, about his upcoming kidney transplant on 1 September.
"Me being here was a distraction from what is pending. I have been able to focus on winning a medal and not think about the operation.
"I have had to modify my training, training is incredibly difficult to recover from, I can't eat as much protein as I would like, I can't process potassium to combat cramps, oxygen can't get to my muscles properly and I am anaemic.
"Having my heats a day apart has really helped me, if the races had been on the same day I wouldn't be here. It has been tough but I have pulled it off."
