Double Olympic champion Laura Trott claimed a thrilling photo finish victory in the IG London Nocturne.
Trott, 21, edged out Hannah Barnes to claim the win for Wiggle Honda Pro Cycling, the team backed by Tour de France winner Sir Bradley Wiggins.
Dani King, who won gold with Trott in the women's team pursuit at London 2012, completed the podium in a 30 minute plus five lap race, held under lights on a specially constructed 500m circuit.
Tom Scully claimed the men's race, pipping Alex Dowsett, who won his first Grand Tour stage with a time trial victory at last month's Giro d'Italia.
Meanwhile, Team Sky's Chris Froome is 51 seconds ahead of his nearest rival coming into the final stage of Criterium du Dauphine.
The race is seen as a key indicator of form ahead of the Tour de France and was won last year by Wiggins.
Froome, second in last year's Tour and a bronze medallist for Team GB at the London 2012 Olympics, will lead Team Sky after an impressive season which has seen him win the Tour of Oman, Criterium International and Tour de Romandie.
