Great Britain clocked a world record in qualifying fastest in the women's team pursuit on day one of action in the Rio Olympic Velodrome.
After Phil Hindes, Jason Kenny and Callum Skinner set an Olympic record in qualifying for the three-man, three-lap team sprint - the day's only medal event - Joanna Rowsell Shand, Laura Trott, Elinor Barker and Katie Archibald set a world record in the four-rider, four-kilometres team pursuit.
The quartet finished in four minutes 13.260 seconds to qualify for Saturday's first round, which is effectively a semi-final.
Britain will meet Canada and must merely beat them to advance to the final. Canada qualified in 4mins 19.599secs, more than six seconds behind Britain.
