Russia's Yelena Isinbayeva sets the 18th global record of her career and wins the pole vault world title when she clears 5.01m at the second attempt. Britain's men's 4x100m relay squad and 1,500m runner Helen Clitheroe make it through to their weekend finals. But defending champions USA go out when they bungle their first baton switch - wrecking Justin Gatlin's bid to win a third gold medal at the championships. But Jeremy Wariner and Allyson Felix add golds to America's Helsinki haul.

Men's 50k walk final.
Sergey Kirdyapkin receives a rapturous reception as he enters the Olympic Stadium to take gold on his world championship debut. The 25-year-old former junior world champion led from early on and secures the global title in a personal best time of three hours 38 minutes and eight seconds. At around the 20km mark he was caught by Aleksey Voyevodin and the pair briefly raced shoulder-to-shoulder. But by 40km Kirdyapkin had shaken off his fellow Russian, who went on to earn silver in 3:41.25. Italian Alex Schwazer powers through late on to claim the bronze in a national record 3:41.54.

Men's high jump qualification.
Britain's Ben Challenger crashes out of the competition when he cannot clear the bar at 2.27m. The Belgrave Harrier did not get off to a great start, failing at 2.20m at his first attempt, but he returned to record 2.24m before going out. But Olympic champion Stefan Holm, who won world silver in Paris, is one of 12 who comfortably clear 2.27m to progress to Sunday's final. Defending champion Jacques Freitag, however, is not among them. The South African fails three times at 2.24m and departs the Olympic Stadium two days earlier than many would have predicted.

Women's javelin qualification.
Britain's Goldie Sayers is all smiles as she qualifies for Sunday's final with her first throw of 60.67m. Olympic champion Osleidys Menendez, the only woman in the field to have thrown over 70m, was first to advance. The Cuban, who also holds the best global mark of 2005 - 68.47m, which she recorded in the same stadium last month - reaches 65.77m to easily top Group A and progress. Germany's Christina Obergfoll is next to join them when she reaches 61.59m. In total 12 throwers advance, including Germany's Steffi Nerius who wins Group B with a personal best 66.52m.

Men's long jump qualification.
Chris Tomlinson fails to qualify for Saturday's final despite a series of season-best jumps. The Briton opens with 7.55m, then follows that up with a wind-assisted 7.83m before slipping back to record 7.64m in qualifying Group A. But the automatic mark for Saturday's final is set at 8.10m and he misses out. In Group B, home favourite Tommi Evila sends the Finnish crowd into a frenzy when he registers a new national record 8.18m to join 11 others in the final. "It was an accident!" Evila admitted. "I wasn't planning to do that but the old record was 8.16m which is pretty close to 8.10m, which is what I was trying to achieve." Dwight Phillips, also in Group B, heads a formidable American contingent with a season's best jump of 8.47m and comfortably advances with a massive wind-assisted 8.59m. But four-time champion Ivan Pedroso, of Cuba, does not go through after failing to make a mark.

Women's pole vault final.
Olympic champion and world-record holder Yelena Isinbayeva is assured of gold when she clears 4.70m. She then goes on to set another global mark - the 18th of her career - when she soars over 5.01m at the second attempt. Monika Pyrek of Poland, takes silver after clearing 4.60m but failing at 4.75m. Czech Pavla Hamackova wins bronze with her clearance of 4.50m.

Women's shot put qualification.
New Zealander Valerie Vili is one of the first to go through when she records a massive 19.87m to set a new Australasian area record and win Group B. The 2003 world silver medallist Nadezhda Ostapchuk, of Belarus, tops Group A with 19.65m.

Men's 4x100m relay heats.
France, Jamaica and Germany all qualify for Saturday's final from heat one - but the story of the race is America's shock exit. Mardy Scales fluffs his handed over to second-leg runner Leonard Scott and the favourites fail to recover and go out - ending Justin Gatlin's bid to complete a golden hat-trick at the championships. US relay captain Maurice Greene said: "Do I feel bad for him (Gatlin)? Yes." And Greene, taking a dig at the poor weather that has dogged Helsinki, quipped: "I just came here for a rainy vacation, I guess." Meanwhile, the British quartet of Marlon Devonish, Jason Gardener, Mark Lewis-Francis and Christian Malcolm also qualify when they come second in a heat two won by Trinidad and Tobago. Japan come third and also go through.

Women's 200m final.
Olympic silver medallist Allyson Felix goes one better than Athens and wins in 22.16. Fellow American Rachelle Boone-Smith takes silver and Christine Arron, of France, the bronze. Olympic champion Veronica Campbell of Jamaica overcooks the bend and flies out of her lane before finishing way down in fifth.

Men's 800m semi-finals.
Northern Ireland's James McIlroy fails to advance despite a season's best performance in the second semi-final. The Larne man clocks 1:45.91 but it is only good enough for seventh in a race won by Canadian Gary Reed in a new national record time of 1:44.33. Russia's Yuriy Borzakovskiy wins the first semi in 1:44.26 while Belal Mansoor Ali tops the third semi in 1:45.35.

Women's hammer final.
Cuban defending champion Yipsi Moreno had looked well on the way to a third consecutive world title at the half-way stage. But her leading mark of 73.08m is bettered by Olga Kuzenkova. The Olympic champion registers a season's best 75.10m with her fifth and final throw of the competition to take gold. Moreno still seems happy with the silver while Kuzenkova's Russian team-mate Tatyana Lysenko claims bronze with 72.46m.

Women's 1500m semi-finals.
Preston's Helen Clitheroe scrapes into the final as a fastest loser. She finishes seventh in her semi in 4:09.13 - but as the first semi was very slow (Maryam Yusuf Jamal won in a lacklustre 4:10.58) the Brit goes through.

Men's 110m hurdles final.
Four-time US world champion Allen Johnson fails in his bid to become the first track athlete to win five world titles in the same event when he finishes third in a very quick final. Ladji Doucoure of France wins in 13.07 to edge China's Olympic champion Liu Xiang (13.08). Johnson clocks 13.10. Doucoure sums it up: "This is a good day for me!"

Women's 4x100m relay heats.
The inexperienced British quartet of Emily Freeman, Emma Ania, Laura Turner and Katherine Endacott run a solid heat and come fourth in 43.83 as USA and Nigeria automatically qualify. But it is not enough to see the GB girls through.

Men's 400m final.
Welshman Tim Benjamin gives his all in tricky lane one and comes fifth in 44.93. As many predicted, Jeremy Wariner adds the world title to his Olympic crown in impressive fashion in a blistering time of 43.93.
