Horses are where the action is today! BBC Live Text is fantastic as ever:
1009: "Watch the modern pentathlon. The first competitor has not managed to jump a single fence! The second one has fallen off!"

Just turned over to see a replay of the faller. Brutal.
1016: Is this normal? There's another faller in the modern pentathlon show-jumping. The course is like a mud-bath and some of these riders look like they've never seen a horse before, let alone ridden one. I'm looking for a modern pentathlon expert in the office... I may be some time.
1020: Little by little, information is dribbling through. Apparently, modern pentathlon competitors have to pick their horses at random, hence lots of fallers, some fences being completely destroyed - and audible gasps of horror from the crowd. It's brutal, but weirdly gripping.
1022: "Re 1020: it's like a live action version of buckaroo."

1025: Bombshell news from the show jumping... A number of horses have tested positive for banned substances - don't know which ones or what substance. Four have been disqualified from tonight's finale - and they will also be dq'd from the team event a few days ago. GB finished 7th in the team event - so we don't think it would affect them - but we believe it could affect the medals. Think something should develop in next 10 mins with a press conference at 1100 BST.
1032: Britain's Sam Weale next to tackle It's A Knockout... sorry, the show jumping at the modern pentathlon. He and his horse try to go through a fence and then fail to jump it at the second attempt and that's 224 penalty points. Which isn't as bad as it sounds.
1032: Who would have thought the modern pentathlon would lead to such a rich vein of comedy texts? But come on people, horses testing positive for banned substances is NOT a laughing matter. And no, it wasn't for a-neigh-bolic steroids. Honestly.
