Charlotte Worthington won the BMX freestyle park event Sunday, making Great Britain the first nation to take gold in all five Olympic cycling disciplines.
The 25-year-old from Manchester fell on her first run in the final but landed the first-ever 360 backflip in competition on her second to score a 97.50.
Hannah Roberts of the USA took silver with a 96.10 on her first run before falling on her second and Nikita Ducarroz of Switzerland claimed bronze with an 89.20.
“I'm over the moon," Worthington said. "I’m still sitting here waiting to wake up. I’ve been thinking about this day for the past three or four years, just going in and out of thinking I can, or I can’t do it.
"I’m literally waiting to wake up right now. It feels like a dream.”
Australia's Logan Martin took the first men's gold medal in the event, his 93.30 on the first run getting the better of Venezuela's Daniel Dhers (92.05) and Great Britain's Declan Brooks (90.80).
