Sophie Thornhill and pilot Corrine Hall led a British gold medal charge in the tandem events on day three of the International Cycling Union (UCI) Para-Cycling Track World Championships in Los Angeles.

The duo claimed victory in the women's B class 1,000 metres time trial.

Their time of 1min 09.55sec proved enough to beat British team-mates Lora Fachie and Hazel MacLeod, who clocked 1:11.09.

An all-British podium was completed by Alison Patrick - already a Paralympic bronze medallist in triathlon - alongside pilot Helen Scott in 1:11.12.

James Ball and pilot Matt Rotherham also won the corresponding men's event for Britain in 1:00.73.

Reigning world champion Neil Fachie and pilot Craig MacLean took silver in 1:02.04.

Australian duo Kieran Murphy and Lachlan Glasspool took bronze.

United States also enjoyed more success as Shawn Morelli won the C4 individual pursuit final on home soil.

The defending champion caught Canadian silver medallist Marie-Claude Molnar before the end of the 3,000m race.

Meg Lemon of Australia finished third in a competition in which there were only three entrants. 

Just 80 are featuring at the World Championships at the VELO Sports Center in Carson, which will play host to cycling if Los Angeles is successful with its bid for the 2024 Olympic and Paralympic Games.

This is less than half of the 215 competitors who took part at the 2016 edition of the event in Montichiari in Italy.

The short notice period athletes were given by the UCI has been widely blamed, with Los Angeles only awarded the event in January.
