China's Jieli Li broke her own world record to clinch the gold medal in the women's C1 time trial in style on day two of the Para Cycling Track World Championships in Rio de Janeiro.

Li completed the 500 metres course in a time of 43.430sec, over a second quicker than the previous mark, to top the podium at the Barra Olympic Park Velodrome.

Britain's Katie Toft, the only other cyclist in the event, was nearly four seconds slower than the dominant Chinese athlete.

Alyda Norbruis of The Netherlands produced a superb individual performance on the second day at the 2016 Paralympic Games venue as she won two titles.

Norbruis clocked 39.886 to oust Amanda Reid of Australia and China's Zhenling Song, silver and bronze medallists respectively, in the women's C2 time trial.

The Dutch star then went on to claim the C1-3 scratch title ahead of Germany's Denise Schindler and American Jamie Whitmore.

The victories for Norbruis added to her individual pursuit triumph yesterday.

"Riding in this velodrome has brought back a lot of good memories," the Paralympic time trial champion said.

"It is so special and I am very proud of how I raced. 

"The scratch race was the hardest. 

"You just have to keep your eyes on the fast ones in front and push, push and push."

There was further time trial success for China as world record holder Zhangyu Li won the men's C1 event, held over one kilometre, in 1min 12.586sec.

Li's time proved too strong for the rest of the field as Arnoud Nijhuis of The Netherlands and Ricardo Ten Argiles of Brazil finished second and third respectively.

Britain's Megan Giglia upgraded the silver medal she claimed in the individual pursuit with gold in the women's C3 time trial in 42.091.

Giglia won the title from yesterday’s individual pursuit victor Denise Schindler of Germany, who took silver, while bronze went to American Jamie Whitmore.

Colombia's Alejandro Perea Arango beat reigning world champion Tristen Chernove of Canada in the men's C2 time trial by clocking a time of 1:13.396.

Chernove was forced to settle for silver in 1:14.105, while China’s Guihua Liang was a second further adrift in bronze medal position.

Britain continued their good start to the Championships as they sealed the men's and women's tandem individual pursuit titles.

Paralympic gold medallists Lora Fachie and Corrine Hall earned the women's crown by clocking 3:31.685, with Griet Hoet and Anneleen Monsieur of Belgium claiming silver.

Katie-George Dunlevy and Eve McCrystal of Ireland were the recipients of the bronze medal.

Stephen Bate and pilot Adam Duggleby ousted world champions Ignacic Avila Rodriguez and Joan Font Bertoli in the gold medal race in the men's event, while the Dutch duo of Tristan Bangma and Patrick Bos took bronze.

The event in the Brazilian city continues tomorrow.
