11.32: And they're off! The home crowd cheers on Great Britain's David Weir in his bid for a fourth London 2012 gold in the Men's T54 Marathon.
1137: Beast alert! I repeat, Beast alert! U.S. golden girl Tatyana McFadden is unleashed in the Women's T54 Marathon. There are five Americans competing in this race, but the big threat to McFadden's FOURTH crown will be Switzerland's Edith Wolf.
1139: Wolf (I told you it was Scary Sunday, didn't I?) has already nabbed two silvers, one gold and one bronze these games. But can she beat "The Beast?"
1203: Meanwile, over at the Men's T54 Marathon...
1218: Hang on. What's this? News is filtering in that U.S.A's Tatyana McFadden has had to stop with a puncture. This could change everything.
1230: It would be heartbreaking for Tatyana McFadden to miss out on a medal after such a fantastic start - and a stellar Games. But with three minutes to make up, it's a big ask.
At the 25km mark, U.S.A's Amanda McGrory leads the pack. McFadden in ninth.
1247: London has turned marathon mad. But don't they know there's another big event on today? Dial M for Murderball...
1250: It's a fight for bronze as the U.S. takes on Japan in the Wheelchair Rugby. The Americans lead at half time 24-21.
1306: A phenomenal end to London 2012 for the “Weirwolf.” He’s taken the marathon in 1 hour and 30 minutes, just one second ahead of Switzerland’s Marcel Hug and Australia’s Kurt Fearnley. There’ll be parties in London tonight, let me tell you.
1312: Gold medallist David Weir:
"The first six miles were the hardest. I felt like I was going to die. I had no energy. But I just had to blank the racing out and think of all the training I'd done."
1325: It wasn't Tatyana McFadden, but it was still a U.S. gold as Shirley Reilley wins the marathon in one hour and 46 minutes. Silver goes to GB's Shelly Woods, bronze to Switzerlands Sandra Graf.
Favorite in this race, Tatyana McFadden is currently ninth at the 35km mark after a puncture forced her to stop.
1345: Disappointment for "The Beast" McFadden after finishing ninth, around 12 minutes after first-placed Reilley. It was just too much for her to recover from such a long time out to repair her wheelchair. Still, three gold medals these Games...you can't complain about that.
1346: Another medal for the U.S. This time in the Wheelchair Rugby where the Americans have taken bronze, beating Japan 53-43. Next up, the battle for gold between Australia and Canada.
1450: Wheelchair Rugby update: Australia are on track for gold against Canada, looking very strong and leading 30-20 in the second quarter.
1553: It pains me too, let me tell you. But I've always been a cup-half-full type of gal. And in just a few short hours the party of the year (can you have two in one year?) kicks off at the Paralympic Stadium...
1620: I’m afraid Sheena’s gone home, but I agree wholeheartedly Venita. These Games have seen the Paralympics receive an unprecedented amount of media coverage. Let’s hope the trend continues in Rio in four years time.
1626: The sun may be setting on the Games, but it is still a scorcher of a day at the Olympic Park. The final event of the entire Paralympics is under way, Russia and Ukraine are drawing 0-0 in the final of the 7-a-side football with 25 minutes played.
