NEWPORT’S Jon Mould endured a tough weekend in the UCI Track Cycling World Cup in Aguascalientes, Mexico.

After an encouraging performance in the men’s omnium on day one at the Velodromo Bicentenario the 21-year-old was lying in seventh position in the multi-race event.

But he suffered on day two and was forced to withdraw due to illness after the pursuit.

And Mould fared no better in the madison event on day three.

He and Leicester’s George Atkins were recently crowned British madison champions but they found the going much harder in Mexico.

The pair began well, picking up a point in the second sprint, but missed the main moves to finish five laps down in 13th.

Mould’s fellow Team USN riders Elinor Barker, Ciara Horne and Amy Roberts had collected team pursuit bronze on the opening day of the competition.

On day two Elinor Barker faced tough competition in the first day of action in the women’s omnium.

She recorded a personal best time of 14.560s in the opening flying lap.

In the points race she finished 15th and she ended the first day in 17th position after the elimination race.

Barker improved on her second day in the omnium to end up 14th.

Her best result came in the individual pursuit, where she recorded a highly respectable 3:39.018 to claim ninth place.

Horne finished 11th in the women’s individual pursuit.
