Joanna Rowsell will ride for her second gold of the Track Cycling World Championships after qualifying second fastest in the women's individual pursuit on day three in Cali.
Rowsell, who was a member of the British squad which won team pursuit gold on day two, will meet Sarah Hammer of the United States in the race for gold in the three-kilometres event.
The 25-year-old from Cheam, Surrey finished in three minutes 30.610 seconds and defending champion Hammer clocked 3mins 29.711secs.
Ireland's Caroline Ryan finished in 3:37.847 to place sixth.
Elinor Barker, who admitted struggling in the team pursuit final, finished in 3:41.609.
Defending champion Becky James advanced to the evening's women's sprint best-of-three quarter-finals at the first time of asking.
James, second-fastest qualifier behind world record holder Kristina Vogel of Germany, beat Holland's Shanne Braspennincx in the first round and met Stephanie Morton of Australia in the second.
The 22-year-old from Abergavenny led out the sprint and had plenty of power to win by half-a-bike length to progress.
Morton fell into the repechage, giving her a second opportunity to advance to the last eight.
Vicky Williamson met Lin Junhong in her second round match but left herself with too much to do entering the final lap and dropped into the repechage.
Jess Varnish was paired with Olympic champion Anna Meares and the Australian pipped the Briton on the line, sending Varnish into the second-chance saloon alongside Williamson.
One of three riders advanced from the repechage and Varnish won her heat ahead of Tania Calvo of Spain and Germany's Miriam Welte, who won team sprint gold on day one and 500 metres time-trial gold on day two.
Williamson was unable to join James and Varnish in the last eight as Morton won their repechage heat.
Ed Clancy was sixth after two of the six disciplines in the men's omnium.
Clancy won the opening event, the flying lap, and was 13th in the 40km points race.
The quarter-final draw in the women's sprint paired James and Varnish together, meaning only one could progress to Saturday's semi-finals.
Meares was the likely last-four opponent, with the Australian paired with Zhong Tianshi in the last eight.
