Zoe Backstedt (L) will celebrate her 17th birthday on Friday, 24 September
Great Britain's Zoe Backstedt and Joshua Tarling have won silver in the junior time trial events at the Road Cycling World Championships in Belgium.
Backstedt ,16, covered the women's 19.4 km course in 25 minutes 16.13 seconds, 10.64 seconds slower than winner Alena Ivanchenko of Russia.
Great Britain team-mate Maddy Leach finished fifth.
Backstedt's fellow Welsh rider Tarling also claimed silver in the men's event while Finlay Pickering finished eighth.
Backstedt, who will ride the road race on Saturday, won gold at the Cyclocross Junior World Cup earlier this year.
Her previous successes include gold in both the time trial and road race at the European Youth Olympics in 2019.
The Pontyclun rider's elder sister Elynor, 19, won bronze in the Junior Road World Championship time trial in both 2018 and 2019.
Her father Magnus took stage victories in both the Tour de France and Giro d'Italia and won the Paris-Roubaix classic in 2004, while her mother, Megan, competed for Wales at the Commonwealth Games.

Tarling previously rode for Team Backstedt, a development squad set up by the former professional. He switched to Belgian team FlandersColor Galloo for 2021, which has proved to be a highly successful year for the 17-year-old from Aberaeron.
He won gold in both the team pursuit and omnium at the European Track Championships, and also won points race gold at the British Track Championships, where he won a silver and two bronzes in other events.
Tarling, who also has the road race still to come on Friday, was more than happy with second place in the World Championship time trial despite leading the timing-board until eventually being overtaken by Denmark's Gustav Wang.
"I'm definitely not disappointed with silver," he said.
"I gave it all I had and I'm relieved to be honest, it was a long time sitting on that hot seat thing. It was nervous, but I'm relieved."
