Team GB’s hopes of a cycling medal on the first day of the Tokyo Olympics came to an early end after Geraint Thomas pulled out of the men’s road race following a crash.

Thomas and teammate Tao Geoghegan Hart fell around 70km (43 miles) into the 234km (145 mile) event which finished at the Fuji International Speedway on Saturday.

Thomas, the 2018 Tour de France winner who crashed in a similar way in last month’s competition, managed to get back on the bike with a bloodied arm and shoulder.

But he pulled into the pits and retired with 60km (37 miles) to go before Ecuador’s Richard Carapaz took his country’s second ever gold.

Another Briton, Adam Yates, narrowly missed out on a medal in a dramatic dash to the finish line.

Fans defied orders to stay away from the race, with hundreds lining the streets to show their support.

Spectators are banned from nearly all the events due to the COVID state of emergency in and around Tokyo.

“I struggled a bit with fatigue and the heat,” she said.
