Live commentary from the Aviva Grand Prix Crystal Palace, Friday, July 24

Idowu's fifth jump looks long but he's just over the board. So close that the decision even riles the usually placid David Vine, the commentator for the meet. Idowu was unlucky there to get the red flag. Just one jump left.

8.00pm Bromley and Blackheath Harrier Montell Douglas runs for GB and Norther Ireland in the 4x100m Women;s Relay. She dropped the baton in Beijing. Expect some very careful handovers.

7.53 Farah storms home to victory. It was a superb race, paced to perfection. 13mins and nine seconds was the time.

7.50 Idowu finally gets a white flag. 17.06m puts him in second place.

7.47Farah is up in a break-away group of four at the half-way stage in the 5,000.

Idowu is all over the place. His second effort sees him just jog into the sand. He's having real problems with his run-up.

7.42Farah looks comfortable after three laps, moving up into fifth llace.

7.35 The men's 5,000m with Britain's top distance runner Mo Farah.

7.32 Men's 800m. Canada's GAry Reed claims it in a close race. Time 1min 45secs.

7.30pm Olympic silver medallist Christian Cantwell from the US has won the men's shot. Not bad, considering an official dropped a shot on his foot before he'd even started. I wouldn't want to be that official. This guy is huge.

Idowu's first jump gets the red flag.

7.20A British 1-2-3. Jemma Simpson comes in first with Meadows second.

The Women's 800m is lining up with Team GB's Jenny Meadows leading the home challenge.

7.15pm On more star spotting news, Iwan Thomas the former GB 400m runner and now Reality Tv staple is up here in the press area. He is wearing battered jeans and a pair of huge workboots and looks like a weathered boyband member. Mark Austin from the ITN News is here, too. He'll have to hurry back if he's on tonight.

7.10pm Bolt has got lane four for the final, despite posting the fourth fastest time in the heats. This meet seems set up around him.

7.02pm Merry announces a prize perhapes more sought after than the 100m crown - the chance to win a dance with Usain Bolt. The Jamaican has been overseeing a competition to find the bestperformer of the "Bolt dance" - essentially his arms-to-the-sky Olympic celebration. The 6ft 5ins sprinter will pick the winner and dance with them after the 100m. Hope they've brought their high heels.

7pm The men's 110m hurdles p> Powell logged 10.19secs in his heat.

6.55pm The never knowingly under-earringed Philips Idowu is warming up for the triple jump. The athletes in the men's 110m are on their marks.

On the second start they're away. Usain Bolt's time was a lowly 10.31. He'll have to pick it up in the final. He promised us a record. The athletes in the 200m women's are complaining to Merry about the wind so that may nix those record hopes.

Ferguson Mckenzie wins the 200m.

6.45pm Women's 200m. Former World Champion Debbie Ferguson Mckenzie is in the middle lane.

6.42 The ageless Seb Coe, a News Shopper favourite, has been sitting two seats away from me from the start but he is brought on to the track to be awarded for his track and field past glory by event host and former 400m runner Katherine Merry.

6.40pm Terrible start from Bolt, he is in third after 50m. He really has to motor to take the tape. Williamson and Team GB's Craig Pickering also make the final.

Another false start. Tyrone Edgar is gone. The starter is really holding that gun.

6.34pm Oh my goodness! False start. It looked like Bolt fellout of the blocks but Edwards gets it.

6.35pm Bolt is on his marks for Heat 2 with GB number one Williamson alongside him.

6.26pm Yohan Blake takes it on the line. Powell is second but he eased off the gas from the 70m mark. Obviously saving some pep for the showdown with Bolt. Still, the second could affect his lane in the final.

A second false start. James Ellington is out. Pressure!

Lewis Francis has a first false start. The pressure is on.

6.20pm. Men's 100m Heat 1. Asafa Powell is in lane 4 with Team GB's the injury-plagued Mark Lewis Francis in Lane 8. The cheer for Powell is deafening. Big Jamaican contingent here tonight.

6.14pm Women's 400m. Britain's GB's Nichola Suanders shows a return to form, but is narrowly edged out for the win in the last 10 metres.

The big event is the men's 100m with the world's fastest man, Usain Bolt, taking on his fellow Jamaican sub 9.8 secs sprinter Asafa Powell and top British stars such as Simeon Williamson.

It promises to be a classic. The heats start at 6.17pm and we'll be keeping you up to speed with developments with live updates.

There's plenty of other events this evening such as the men's 200m, featuring American Tyson Gay, the only man to have run faster than Bolt over 100m this season.
