There was a case of American dominance at the annual Fifth Avenue Mile event in New York at the weekend, with Jenny Simpson and Jordan McNamara both victorious.
Simpson - the 1500m Diamond Race winner - continued her excellent recent form as she successfully defended her title.
The 28-year-old opened up a gap with about 200m to go and, despite pressure from compatriot Brenda Martinez, hung on for the win in a time of four minutes and 19.4 seconds and in doing so becomes the first ever three-time winner of the event.
British athletes Hannah England and Laura Weightman finished seventh and 11th respectively, the former clocking 4:23.1 - just half a second outside the time she clocked to finish third in the same event in 2011 - with Weightman coming home in 4:26.9.
Ireland's Ciara Mageean finished third, but it was Simpson who stole the show, completing what has been a very good year for the 2011 world champion.
As well as winning the overall Diamond League race for the 1500m, Simpson also lowered her personal best to 3:57.22 and looks set to challenge for medals yet again at next year's world championships.
McNamara pips Heath
In the men's race, McNamara won in a sprint finish ahead of fellow USA runner Garrett Heath. Both men clocked 3:51.0 with Irishman Paul Robinson in third.
It was Heath who had made the first meaningful push for the line, accelerating with a quarter of the race to go and leading up until the final few metres where he was pipped by the 27-year-old McNamara.
