Welsh cyclist Becky James won the British women's 500m Time Trial at the National Track Championships in Manchester on Wednesday.
The 20-year-old from Abergavenny was last to go and recorded a time of 34.763 seconds, beating Victoria Williamson (35.749sec) into second.
Danielle Khan (36.04sec) was third, with James' sister Rachel in fifth.
There was also joy for James' Welsh compatriot Owain Doull after he became the men's Individual Pursuit champion.
Doull had topped the times in qualification and rode down Jon Dibben in the final.
Paralympic gold medallist Mark Colbourne was forced to settle for silver in the Paracycling Time Trial, with visually impaired Sophie Thornhill, piloted by Megan Boyd, taking the win.
James will defend her Sprint title on Friday and then her Keirin crown on the last day of competition on Sunday.
The James sisters will also contest the Team Sprint in Manchester, with the finals of that event set for Saturday.
"This is the start of my season now," James told British Cycling.
"The beginning of the season hasn't been a very good start with appendicitis and an Achilles injury.
"So this is the beginning of my season and it is really good to go out and set a PB [personal best] when I'm still in a hard block of training."
