Victoria Pendleton's Olympic odyssey was set to continue into the final day of the London 2012 track programme after the Briton advanced to the semi-finals of the women's sprint.

Defending champion and six-time world sprint champion Pendleton advanced with a 2-0 best-of-three quarter-final win over Olga Panarina of Belarus.

The 31-year-old cyclist from Stotfold was seeking a third gold to become Britain's most successful female Olympian and is set to retire after tTuesday's racing.

Friday's victory in the keirin saw Pendleton move level with athlete Kelly Holmes, swimmer Rebecca Adlington and sailors Shirley Robertson, Sarah Ayton and Sarah Webb on two Olympic gold medals.

Pendleton was a comfortable winner of the first bout with Panarina and a decider was not required as the Briton won the second contest by 10 metres, showing her blistering form.

Pendleton was poised to meet Kristina Vogel in the last four after the German beat Lithuania's Simona Krupeckaite 2-0. Australia's Anna Meares, Pendleton's perennial rival, advanced to the last four with a 2-0 win over Lyubov Shulika of Ukraine.

Meares was poised to have to wait to discover her opponent as Guo Shuang of China drew level at 1-1 with Cuba's Lisandra Guerra Rodriguez and a decider was required.

Laura Trott was third after two events of the two-day omnium. The 20-year-old world omnium champion from Cheshunt won team pursuit gold on Saturday and clocked 14.057 seconds in the flying lap to win the opening event.

Trott finished 10th in the 20km (80 lap) points race, winning the final sprint as Poland's Malgorzata Wojtyra won as one of nine riders to lap the field and claim 20 points.

Trott was the leading rider behind those who gained a lap, but slipped one point off the pace as Sarah Hammer of the United States took the lead after two events on 10 points, with Canada's Tara Whitten second on count back.
