from Richard Lewis in New York
Paula Radcliffe, chasing a fourth victory here and a third successive one, has yet to make a break as she leads a group of six in the ING New York Marathon here this morning.
The women's elite field made it through 20km in 1:10:08 with Radcliffe setting the standard ahea of Christelle Daunay, of France, Ethiopian Derartu Tulu, Russian Ludmila Petrova, Kenyan Salina Kosgei and Magdalena Lewy Boulet of the USA.
It was a dramatic morning for Kosgei who tripped early on the race, with Japan's Yuri Kano crashing down behind her.
Kano was among those expected to challenge Radcliffe but by 20km she was more than two minuts behind the rest such was the effect of her fall.
But Radcliffe powers - more updates at 35km.
