UCI Day 6: Young riders depart Doncaster bound for Harrogate Circuit in cycling Road World Championships

Some of the world's best young cyclists have rolled into action in Doncaster this morning, as the UCI Road World Championships visits South Yorkshire for the first time.

Hundreds of schoolchildren waved off the Junior Women's Road Race at a new purpose-built cycle track at Doncaster Dome.

WATCH: Jonathan Brown visits the new track, including its unique cobble climb (last month).

The road race set off on the 86km route at 8.40am.

The Women's competition was won by America's Megan Jastrab, in a time of 2:08:00. That meant she averaged more than 40.3 kmph.

The men's Under-23s road race begins at the Doncaster Dome this afternoon.
