The line-up includes two-time Chicago Marathon winner Florence Kiplagat, Helah Kiprop and debutant Vivian Cheruiyot.

Mary Keitany missed out on Olympic selection after finishing ninth at the Virgin Money London Marathon last year, but the two-time champion is back in excellent form and leads arguably the greatest women’s field ever assembled for the IAAF Gold Label Road Race today.
