Three-time Olympic champion Kenenisa Bekele won the men's race at the Great Manchester Run, finishing the 10km course in a time of 28 minutes and eight seconds.
Kenya's Wilson Kipsang came second.
The result was mirrored in the women's race as Bekele's fellow Ethiopian Tirunesh Dibaba beat Kenyan Edna Kiplagat, finishing in 31:16.
Richard Goodman and Gemma Steel were the highest-placed Britons in sixth and eighth respectively.
The men's and women's elite races developed in near-identical fashion, with a group of three athletes quickly establishing a lead over the field.
And Bekele and Dibaba both displayed their superiority in the final kilometres, easing clear of their Kenyan rivals to finish comfortably ahead.
The wheelchair races were dominated by British athletes, with Simon Lawson finishing nearly three minutes ahead of second-placed Brett Crossley, while Shelly Woods won a closer-fought women's contest, 14 seconds in front of Jade Jones.
