Great Britain broke the women's team pursuit world record on Thursday evening by almost six seconds.
Team GB's Laura Trott, Joanna Roswell, Ciara Horne, Elinor Barker and Katie Archibald smashed the record with a time of 4:13.260 on their qualifying race.
It goes without saying that fans in the velodrome were very pleased.

World Record for the GB girls in the velodrome. It's only the qualifying for #CyclingTrack and we're already showing them how it's done!

Watching us wreck the velodrome as a British person and now I know how Americans feel watching the gymnastics. #CyclingTrack

Woohoo! And now for Britain to smash their own world record in the finals (fingers crossed). No pressure, girls.
