Double Olympic champion Mo Farah secured victory at the Bupa London 10,000 for the fifth year in a row.
Farah broke away from the domestic field at the two-kilometre mark and crossed the finish line at the Mall in a time of 29 minutes and 13 seconds.
The time was eight seconds quicker than the 5,000m and 10,000m Olympic champion managed in the event last year, but some way short of the 27 mins 44 secs British record he set in 2010.
Farah, whose main focus for 2013 is repeating his Olympic double at the World Championships in Moscow this summer, said: “It was most important to win the race today, I wasn’t really looking for a time.
“It was really important to me to win my fifth title. Running in London is fun for me because I don’t often race here. But it’s going to get serious from here,” he added.
“I’ve got my first real test next Friday at the Eugene Diamond League and I’m very excited about that.”
Phil Wicks finished second yesterday, coming in 52 seconds behind Farah, with Phil Nicholls another 10 seconds back in third.
Katrina Wootton won the women’s race by a similarly large margin from the former world junior 1,500m champion Steph Twell, with Emily Pidgeon third.
Like Farah, Wootton led from the two-kilometre mark and stretched away over the rest of the course to claim victory on her London 10,000 debut in 32:37, just 14 seconds outside her personal best.
Twell clocked 33:34 in second, with Pidgeon another 12 seconds adrift.
