Men's T54 marathon
So, let's bring you up to date with what happened earlier today.
David Weir's miserable Paralympics ended in disappointment as he was forced to withdraw from the men's T54 marathon after a crash damaged his wheelchair during the race.
Weir has won six gold medals in his career but will return home empty handed from Brazil. He is certainly not a happy man.
