Rudisha breaks record again

Rieti - Kenya's David Rudisha set a world record in the 800m for the second time in a week and Jamaica's Nesta Carter ran 9.78 seconds in the 100m at the Rieti Grand Prix on Sunday, tying American Tyson Gay for the fastest time this year.

Rudisha clocked 1 minute, 41.01 seconds in the two-lap race, shaving 0.08 seconds off his mark set last weekend in Berlin.

Helped by a tail wind of .9, Carter used a strong finishing kick to lead an extremely fast field, with seven of the eight entrants clocking 10 seconds flat or under.

Ryan Bailey of the United States was the runner-up in a personal best 9.88, Mario Forsythe of Jamaica finished third in a personal best 9.95 and Christophe Lemaitre of France crossed fourth in a national record 9.97.

In the 110 hurdles, David Oliver of the United States timed 13.01, far off Dayron Robles' world record of 12.87 but fast enough to shave 0.06 seconds off Colin Jackson's meet record set in 1994.

Oliver, who has run under 13 seconds five times this season, knocked over two hurdles midway through his effort.

Rudisha was helped by his friend and pacemaker Sammy Tangui, who set a blistering speed for the first 400 meters. Rudisha then sprinted away from the field in the last few hundred meters, crossing 20 meters ahead of his nearest competitor, fellow Kenyan Boaz Kiplagat Lalang, who timed 1:42.95.

Until a week ago, Wilson Kipketer of Denmark had held the record of 1:41.11 for 13 years.

A 21-year-old former world junior champion, Rudisha had promised to return to Rieti after bursting onto the senior scene with a then African record of 1:42.01 last year at this meet in central Italy.

It is the eighth world record set at the Raul Guidobaldi stadium, following Asafa Powell's then 100-meter mark of 9.74 established three years ago.

With Powell and current world record holder Usain Bolt (9.58) both out injured, Carter and Gay now share the 2010 lead in athletics' signature race.

Gay ran 9.78 into a headwind on a wet track in London earlier this month.
