Laura Trott enters the final event of the omnium in as good a position as she could hope to be, after extending her lead in the penultimate event, the flying lap.
Only the points race remains in the women's omnium, and defending champion Trott heads into the race with a tally of 196 points to second place Jolien D'Hoore's 172.
Trott put in a time of 13.708 in the flying lap competition to beat Annette Edmondson's (Aus) time of 13.878. Trott has now won three of the five events so far with second places in remaining two.
D'Hoore lost further ground with a seventh place finish in the flying lap, but remains in second place on the same points as the USA's Sarah Hammer, who sits in third place.
The women's points race is scheduled for 21-05 UK time.

James qualifies as Marchant drops out
Becky James continued her remarkable form as she beat Elis Ligtlee (Ned) 2-0 in the women's sprint to reach the gold medal final. The Welshwoman rode away easily from Ligtlee, who couldn't match her pace in either of the two sprint races.
James won't be joined by fellow Brit Katy Marchant however, after she lost 2-0 to Germany's Kristina Vogel. Marchant will now ride in the bronze medal races against Ligtlee.
The first of the women's sprint finals is scheduled for 21-44 UK time.
Kenny into keirin final
Jason Kenny stormed ahead of the field in the first of the kierin semi-finals and rode over a bike length ahead of the field across the line.
There was no-one who could match the Briton's speed and he now enters the final of the keirin, where he could win his third gold medal of the Games and equal Chris Hoy's record of six.
Mathijs Buchli (Ned) and Azizulhasni Awang (Mas) also qualified from Kenny's heat.
