Tomlinson says he has trained harder than ever this winter

Long jumper Chris Tomlinson added a fourth silver for Great Britain at the World Indoor Championships in Spain.

The 26-year-old reached 8.06m with his opening jump to earn his first major medal but missed out on gold by 2cm behind South African Godfrey Mokoena.

"I had a reasonable time, it would have been better if I had managed to win, but it's my first medal," he said.

"I kept thinking 'is 8.06m enough to win it?' But if someone had offered me this before, I would have accepted it."

Highlights:Tomlinson takes longjump silver

Allan Scott reached the men's 60m hurdles showdown but finished sixth in 7.65 seconds as Olympic 110m hurdles champion Liu Xiang won gold.

Liu had not raced indoors before arriving in Valencia but his world class shone through as he raced to gold in the men's race in 7.46secs.

American Allen Johnson became the oldest ever world indoor medallist as he took silver at the age of 37 ahead of joint bronze medallists Russian Evgeniy Borisov and Latvia's Stanislavs Olijars.

606: DEBATE On this showing Jenny Meadows looks like a medal chance Isabre

Jenny Meadows ran a superb 800m race to qualify for Sunday's final in Spain.

Meadows, 26, maintained an even pace to finish second in one minute 59.58 seconds and in the final she will be up against seven-time champion Maria Mutola.

In the men's event, Nottingham-born Richard Hill went out after battling to fourth in a testing semi-final in 1:47.82.

Sarah Claxton was unlucky not to make it through to the women's 60m hurdles final after finishing joint fourth with Aleksandra Antonova in her semi-final.

They both ran 8.07secs, meaning nine athletes qualified for the final.

But with only eight lanes at the Palau Velodromo stadium, organisers judged the Russian had beaten the Brit by 0.001secs.

American Lolo Jones won the final in 7.80secs ahead of compatriot Candice Davis and Cuban Anay Tejeda.

Britons Helen Clitheroe and Lisa Dobriskey followed each other home in ninth and 10th in the 3,000m final as red-hot favourite Meseret Defar raced to victory.

The Ethiopian kicked at the bell and pulled away from the field to cross the line in 8:38.79 and claim a third straight World Indoor gold.

Kenya's Daniel Kipchirchir Komen claimed the 1500m title after race winner Deresse Mekonnen was disqualified for stepping off the track.

The result also saw host country Spain win their first two medals with Juan Carlos Higuero second ahead of Arturo Casado.

American Bryan Clay leads the heptathlon ahead of Czech Olympic champion Roman Sebrle after dominating the first four events.

Clay had an imperious first day in the heptathlon including a shot put personal best

The American won the opening 60m in 6.71secs, the long jump with a leap of 7.75m and the shot put with a personal best throw of 16.21m.

He then climbed to 2.09m in the high jump to take a 174-point lead over Sebrle.

World record holder Yelena Isinbayeva needed just two clearances at 4.65m and 4.75m to win her third World Indoor pole vault title in a row.

Cuban world outdoor triple jump champion, Yargelis Savigne, added the indoor crown to her collection with a jump of 15.05m.

Greece's Hrysopiyi Devetzi had led the competition with her fourth-round leap of 15.00m until Savigne pulled out her winning jump in the final round.

There was another a ding-dong battle between Swede Stefan Holm and Russian defending champion Yaroslav Rybakov in the high jump.

Olympic champion Holm failed twice at 2.30m but finally clinched gold when he raised the bar and cleared 2.36m. Rybakov's best clearance of 2.34 was good enough for silver.

There was bad luck for pole vaulter Steve Lewis and 1500m runners Susan Scott and Jemma Simpson who went out.

Lewis, a Commonwealth bronze medallist in 2006, could only reach 5.35m, which was not enough to get into the top eight.

German Tim Lobinger was the best qualifier after sailing over in 5.70m.

Simpson claimed a personal best of four minutes 11.17 secs in her 1500m heat but it was not good enough to advance to Sunday's final.

Scott clocked 4:10.39 but also failed to go through.

Richard Buck was also run out of it in the men's 400m semi-finals, finishing fifth with a time of 47.60secs.

Earlier, there was a big upset in the men's 60m hurdles when title favourite Dayron Robles, who has a world-leading 7.33secs, failed to get beyond his first heat.

The Cuban jogged out of his blocks, thinking there had been a false start, only to see the rest of the field streaking away from him.

He trailed home last in 8.53sec in a heat that also included Liu.
