Just to sound like my Auntie Jennifer, haven't these last few days flown by? It's day six in Berlin and the drama is brewing on and off the track.
Usain Bolt's going for a world sprint double when he runs in the 200m final a bit later. Can he break another world record four days after being crowned 100m champion?
There's plenty of other stories keeping us on our toes today. Marathon star Paula Radcliffe pulls out after failing to recover from foot surgery. Has she had her day? Will she be back?
Then of course there's talk of the town Caster Semenya. Ahead of the race when the South African became 800m world champion, the international governing body IAAF announced she would have to undergo a gender test.
Denise Lewis called Semenya's treatment "absolutely dreadful", while Michael Johnson says the IAAF is doing the "right thing" but adds "the way they're dealing with it is all wrong".
What do you think?
Back on the track - not a bad start to Thursday for the Brits. Michael Rimmer makes the 800m semis and Steve Lewis qualifies in the pole vault.
And for this evening, as well as Bolt's 200m rush for gold, GB's Mo Farah is in the 5,000m heats, as is Kenenisa Bekele who's going for a long distance double, there's the decathlon and Blanka Vlasic is up for the high jump.
What a day. Get your thoughts cranked up right now.
