Track Cycling World Cup: Britain's Katie Archibald wins silver in the omnium in Manchester
Britain's reigning World and European champion Katie Archibald took silver in the omnium at the Track Cycling World Cup in Manchester.
The 23-year-old, who successfully defended her European omnium title in Berlin last month, was in third place after the opening two rounds.
The Scot won the elimination race but could not hold off American Jennifer Valente in the final points race.
Wales' Jonathan Mould claimed a silver in the men's scratch race.
With two sprints remaining in the points race, Archibald trailed Valente by three points as the event went down to the wire.
Ireland's Lydia Boylan denied Archibald the five point-win on the penultimate sprint with Valente snatching a point, meaning the American held a one-point lead going into the final sprint.
And Archibald did not have enough in the legs as Valente sat on her shoulder before driving past the Scottish rider on the final lap to take a thrilling gold.
