Live - World Athletics day eight

25 August - 2 September

Great Britain have hopes of adding to their medal tally in the men's and women's 4x100m relays on day eight of the World Championships in Osaka.

America's double sprint champion Tyson Gay is targeting a third gold in the relay, but Asafa Powell is also intent on leading Jamaica to the title.

His compatriot Maurice Smith has maintained his decathlon lead with the javelin and 1500m still to go.

Britain's Jo Pavey contests her second final of the event in the 5,000m.

1104: Canada's Chantal Petitclerc presses on at the bell and the world record holder takes it in three minutes 37.10 seconds in controlled fashion from Switzerland's Edith Hunkeler and American Jessica Galli. Woods got trapped on the inside on the final lap and comes in last.

1101: The first action out on the track is the women's 1500m wheelchair race where Shelley Woods represents Britain in the three-and-a-half lap event, and it looks like a tactical race as no-one is wanting to set the pace early on.

1100: The penultimate day of action in Japan signals relay time, which means just about anything could happen, and probably will.

The British quartet of Christian Malcolm, Craig Pickering, Marlon Devonish and Mark Lewis-Francis got the baton round safely in their heat to reach the final.

But four teams qualified with faster times so the Brits now need to add some pace to their safe hands.

Five-time Olympic gold medallist and the BBC's wise pundit Michael Johnson says the only tactic they have to employ is to focus on their own race and see where they finish. But will they?

There could be a better chance of a medal in the women's 4x100m as Laura Turner, Montell Douglas, Emily Freeman and Joice Maduaka went through as the third fastest qualifiers in 42.82.

The 4x400m heats for the men and women also get under way and again Britain will expect to be strongly placed.

The medal count for today is as follows: there are five to be settled in the evening session in the women's 5,000m, men's pole vault, decathlon and those pesky sprint relays.

Professional athlete Tyson Gay says: "I am extremely tired." We hear you Tyson but come on it's day eight, we're almost on the home straight now.
