Dame Kelly Holmes starts Birmingham Half Marathon
Zersenay Tadese surged clear after 10km to clinch a third successive World Half Marathon title in Birmingham.
The Eritrean lowered the championship record he shared with Shem Kororia by a massive 21 seconds to finish in 59 minutes and 35 seconds.
Tadese was followed home by Kenyan Bernard Kipyego, with Andrew Lemoncello the first Briton home in 26th.
Pre-race favourite Mary Keitany easily claimed the women's title, the Kenyan leading from start to finish.
Tadese triumphed by more than a minute in a new championship record
Keitany smashed the championship record of Britain's Paula Radcliffe, who was forced to miss the race with tonsillitis, to triumph in one hour, six minutes and 36 seconds.
Team-mate Philes Ongori, who passed Ethiopian Aberu Kebede in the closing stages, finished second in 1hr 7mins 38secs as Kenya also claimed the team title, with Ethiopia second and Russia third.
The British women, led home by Claire Hallissey in 25th position, finished seventh in the team standings.
Andy Lemoncello had a great run, but a few of the guys could maybe have done better
UK Athletics' endurance coach
Britain's men finished 14th, with Kenya winning a fourth successive team title.
"The girls did very well finishing seventh. It's a young team with a lot to learn," said UK Athletics' endurance coach Ian Stewart.
"I'm slightly disappointed with our men's team position - it was a very fast course but it's quite difficult in places, but it's the same for everyone.
"Andy Lemoncello had a great run, but a few of the guys could maybe have done better. But it's a learning curve.
"Long-term we have a few guys who are stepping up to the marathon, but that's where we're at right now."
