A roar from Valerie Adams as she lets the shot put fly and the world champion improves on her earlier attempts, setting another world leading distance of 20.67m. The New Zealander on course to win gold.

Luke Cutts knows how to work a crowd and leave the rest of us with jagged fingernails. The Briton clears 5.65m with his final attempt. Phew. The bar rises to 5.75m and seven men remain.

"Since Ashton's burst on to the scene he's had a complete stranglehold on the decathlon and heptathlon. In the heptathlon we see him at his very best - without his 'weaker' decathlon events like the discus and the javelin. It's not 10 events, but it's still long and demanding."

Eaton collects 6632 points, 13 points behind the world record but still the second-best score in history. Andrey Kravchenko of Belarus (6303 points) secured silver with Belgium's Thomas van der Plaetsen (6259 points) third.

Ashton Eaton is grimacing as he crosses the line but he fails to break the world record. Never has a man looked so disappointed after winning a gold medal.

What's going on on the track? Oh, you know, people are running. When I say people, I mean heptathletes and Ashton Eaton is aiming to break his own world record but the American doesn't seem to be on track to do so as we approach the final lap of the 1000m.

Britain's Luke Cutts has failed with two clearances at 5.65m but the Sheffield athlete might just be teasing us. There's still a three-way tie for first place, with Greece's Konstandinos Filippidis, Germany's Malte Mohr and Czech Republic's Jan Kudlicka setting the standard by jumping 5.65m on their first attempts.

iaaforg:, external Yekaterina Koneva wins the triple jump title with 14.46m, the shortest winning distance since the inaugural title in 1991.

Oof! That was close, just one centimeter between gold and silver. Fine margins. There isn't much of a celebration from Ekaterina Koneva, though, whose 14.46m leap was enough to secure gold. The Russian simply walks over to hug silver medallist Olga Saladukha (14.45m). Saladukha is from Ukraine. Jamaica's Kimberly Williams (14.39m) takes bronze.

Former marathon champion Paula Radcliffe on BBC Sport: "With a lap to go Aregawi looked so so easy. I thought the championship record was going to go but it looked like she was just going for the win."

Aregawi seems to be gasping for breath ever so slightly as she strolls about near the finishing line but victory was always going to be hers. There was a battle for silver, however, which eventually went to Ethiopia's Axumawit Embaye (4:07.12) who pushed Morocco's Rababe Arafi (4:07.53) into third.

Pre-race favourite Abeba Aregawi led coming into the final lap and it was a handsome victory for the Swede, who crossed the line in 4:00.61.

The men's 4x400m team also won their semi-finals, while Will Sharman and Andrew Pozzi both reached Sunday's 60m semi-finals and Shara Proctor and Katarina Johnson-Thompson are both into Sunday's women's long jump final.

"I couldn't be happier, that's all I needed to do," said Proctor, 25. "I didn't get the big Q, but I was third in qualifying and good enough to make the final. I always come out to challenge for the medals and I feel in great shape."

There was some bad news, though, there always is, because Olympic bronze medallist Robbie Grabarz failed to reach the men's high jump final. The 26-year-old and team-mate Tom Parsons were both unable to clear 2.28m.

There's a bit of news to report on from the morning session and it is mostly good because Britain's women's 4x400m relay team, led by world outdoor 400m champion Christine Ohuruogu, eased through their heat and are on course to defend their title.

"We're defending world champions and we've got girls who know how to run indoors and who are confident," said Ohuruogu, who is running in the same team as her sister, Vicky, for the first time at an international championship.

"It's a battleground out there so we need to hold our nerve and hopefully defend our title."

The women's 1500m final will begin shortly and the woman to keep an eye on is Sweden's Abeba Aregawi who, Steve Cram says, should win this by a street.

Tom Gooch: , externalDidn't realise but Luke Cutts could well be the most Yorkshire sports person ever.

In the women's triple jump final, Russia's Ekaterina Koneva leads the way with a 14.46m leap. Meanwhile, New Zealand's reigning world champion Valerie Adams (who else?) is leading in the women's shot put final thanks to a 20.06m throw.

The men's pole vault final is under way, of course, and Britain's Luke Cutts is currently seventh after clearing 5.55m with his second attempt. Greece's Konstandinos Filippidis, China's Yancheng Yang and Germany's Malte Mohr top the leaderboard thanks to first-time clearances at 5.55m. Early days, though, in that competition.
