Just in case you haven't heard it yet - Cian O'Connor is back in the equestrian final and jumps second at 12pm after another horse pulled out.
That's great news for Cian. You wonder is it written in the stars for him. Remember, he wasn't picked on the Irish team. He was first reserve for that too. He starts with a clean slate now. It means that Blue Loyd won't be competing in the Aga Khan Cup at Dublin next week now but you can't have everything!
Mo Farah running in the first 5k heat as he chases one of those great doubles. Think Lasse Viren, The Flying Finn. Looked like a man for whom all the pressure had been removed when introduced to the crowd, not that he seemed a barrel of nerves before the 10k final.
Morning from the Olympic Stadium, yet again it's full, yet again it's humid.
Three laps to go in the first men's 5000m semi, featuring 10,000m Olympic champion Mo Farah. He's looking comfortable in the pack.
No trouble for Farah, the only European representative in the top six, as he comes home third.
Wait for the begrudgers bemoaning Cian's elevation into the final. Good luck to him and I hope he wins a medal.
@Peter Towe was thinking that as I wrote "clean slate". There is no clean slate for some.
Alistair Cragg's best time this season is 13:32.76. Best loser's time was 13:27.06, so Cragg may have to crank it up a bit today.
Here comes semi-final 2 of the men's 5000m featuring Alistair Cragg. His season's best is third slowest of the field, but PB is comparable.
Cian will be second to jump in the final which starts at 12.
Alistair Cragg's Heat 2 of the 5000m is under way
Strung out with 11 laps to go, Cragg is 11th.
Cragg is in the middle of the field which is all bunched up.
Top five and five fastest losers go through.
This is looking faintly familiar to me when it comes to Alistair Cragg at major championships
Nine laps to go, Cragg is 16th. Strung out but still together.
Eight laps to go, Cragg is 17th. Still one long string kept together.
The pace looks a tad slow.
A gap has appeared between Cragg and the leading group. He is trying to close.
Seven laps to go, Cragg is 18th and has fallen behind the lead group. Top five and five fastest losers through.
Pace has stepped up and Alistair Cragg is quite isolated 20m behind the lead group of 15.
Cragg is 18th with six laps to go, but has got back into the slipstream and rejoined the lead group.
Rupp, who was silver medallist behind training partner Mo Farah in the 10k, taking them on, after Craig Mottram had done the early donkey work. It's certainly not excessively fast.
What's happening with Cragg? If it's slow then he should be able to keep up.
