Handlebars
The 21-year-old from Bakewell was in good company and was behind only Bresset at the end of the first lap and the Frenchwoman forged on in the second, leading again, with Spitz second and world champion Catharine Pendrel third. Last was fifth, 11 seconds behind.
Gould joined Spitz and Bresset in the front group as the Frenchwoman went through the start-finish line with a lead of four seconds with three laps to go. Last was 34 seconds adrift.
Spitz went over her handlebars with Gould behind her on a steep rocky section known as Deane's Drop as Bresset went further clear.
Bresset appeared unstoppable as she passed through the two-laps to go marker in 1hr 40secs, with Spitz 33secs adrift and Gould trying to stay with the German. Last was 1min 22secs behind in fifth.
With one lap to go Bresset led by 57 seconds and she comfortable held on to claim France's first cycling gold of the Olympics.
