Anna Kiesenhofer, without any teammate to help with during the race, jerked directly in the ladies' Olympic line race but got some other cyclists with her.
With 40 miles left, the next jerk came - and this time she shook off the rest of the field.
She was then able to cross the finish line as an Olympic gold medalist, something that few would expect.
- This must be the biggest bang in the ladies' cycling history, says commentator Anders Adamson in discovery +.
Kiesenhofer, who has a doctorate in mathematics, won by more than a minute.
For Austria, it is the first medal in cycling since 1896.
The favorite tipped Dutch team, instead had to fight for silver and bronze.
Annemiek van Vleuten recovered from an early crash and snatched the silver.
Italian Elisa Longo Borghini won a sprint and took care of the bronze.
