All the action as it happened on a dramatic night in the Olympic Stadium.
1845 BST: Five days after dropping out of the marathon, Britain's Paula Radcliffe enters the Olympic Stadium to try and salvage some pride in the 10,000m.
She left the Olympic Village at 1700 BST, arriving at the stadium 30 minutes later where she headed to the warm-up track to work on her last-minute preparations with husband and coach Gary Lough, plus Alan Storey, the British team's endurance coach.
1947 BST: Radcliffe, after the toughest week in her life, stands on the start line. Wearing dark glasses, she looks nervous.
24 laps to go: Paula is settling into her running. She is in the middle of the pack, rather than going to the front as she invariably has in the past.
23 laps to go: Conditions for the race are in stark contrast to Sunday's marathon, which was staged on the hottest day of the year in Athens.
Tonight it is warm but not horrendously so.
22 laps to go: The pace is slow as the athletes take account of the humidity. Radcliffe is fourth from the front, looking comfortable.
20 laps to go: The field is spreading out but no-one has yet tried to make a break.
All the favourites - Dibaba, Kidane, Tulu, Kiplagat - are all there in the top eight.
18 laps to go: Radcliffe, unable to take another step just five days ago, goes to the front.
16 laps to go: Kiplagat takes over at the front. Radcliffe drops back to seventh but she is still right there.
15 laps to go: Tulu decides to slow it down. After a fast lap from Kiplagat, the pace slows.
14 laps to go: The Ethiopians and Kenyans go to the front. The pace has picked up again and Radcliffe is hanging in on the back of the lead group.
13 laps to go: The fastest lap of the race so far as Kidane takes her turn at the front. At the halfway stage, the time is 15 minutes 34 seconds - below Radcliffe's personal best, but conditions are much harder than she is used to.
12 laps to go: Radcliffe is being dropped. Any chance she has of a medal hangs in the balance. The race is being dictated to her.
11 laps to go: Paula is going off the back of the main group. The three Ethiopians are leading and Radcliffe is feeling the pace.
10 laps to go: Radcliffe is now fighting her own private battle. She is dropping further and further off the pace. A medal is now out of the question.
Nine laps to go: The seven-strong leading group is now 60 metres clear of Paula. She is in real trouble.
Eight laps to go: Radcliffe has gone. She steps over the curb into the infield, and her Olympics are over.
Seven laps to go: At the front of the field, the Ethiopians are leading with Kiplagat and China's Xing Huina close behind.
Six laps to go: Now Kiplagat goes and injects more pace into the race. Kidane sits on her shoulder and moves to the front with Dibaba looking very comfortbale, letting the others do the work.
Four laps to go: Just over a mile to go. The race is coming to a boiling point. Kidane leads but that group of five - three Ethiopians, Kiplagat and Xing Huina - is still together.
Two laps to go: Two-time Olympic champion Tulu is hanging on, hoping she can use her sprint finish over the last lap as she has so many times before.
The bell: Kidane is trying to run the finish out of Tulu. Tulu is three metres off but she is winding it up, ready for the final showdown.
The finish: A massive shock as China's Xing Huina sprints to gold - her country's second gold medal in less than an hour.
Dibaba takes silver after Xing Huina comes past her with 80 metres to go, with Tulu in bronze.
Xing Huina punches the air with delight. She ran a brilliant race, sitting with the leaders and letting the others do all the work, and then striking for home at the perfect time.
Gold: Xing Huina (China)
Silver: Ejagayehu Dibaba (Ethiopia)
Bronze: Derartu Tulu (Ethiopia)
