Trott wins in London

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.
