Mark Colbourne sets world record in 200m FS TT victory
Paralympic gold medallist Mark Colbourne set a new MC1 world record on day two of the National Track Cycling Championships in Manchester.
Colbourne triumphed in the 200m flying start time trial, finishing in 14.177 seconds, comfortably inside the previous record time of 14.875sec.
A British title continues Colbourne's stellar year after his Paralympic gold.
He broke the world record twice in a day as he claimed C1 3km individual pursuit gold at London 2012.
It also made up for the disappointment on day one when Colbourne was forced to settle for silver in the paracycling time trial, with visually impaired Sophie Thornhill, piloted by Megan Boyd, taking the win.
This time the positions were reversed, with Colbourne taking victory with 104.923 points ahead of Thornhill and Boyd (100.778) and Mazyar Ossamisaeed (98.562).
Another Paralympic champion, Jody Cundy, had to settle for fourth in the able-bodied kilo, behind winner Kian Emadi, who finished in a time of 62.435sec.
World junior road champion Lucy Garner claimed victory in the women's 3000m individual pursuit, reeling in early leader Charline Joiner to win in 3:52.414.
George Atkins won the men's points race, finishing with 64 points ahead of Colbourne's Welsh compatriot Owain Doull (59) and Zac May (53).
