The 21-year-old Timaru cyclist Shane Archbold won the omnium at the UCI World Cup in Melbourne last night.
Archbold produced a series of consistently high placings in the gruelling six-event competition that has been added to the Olympic schedule for London 2012.
He disposed of world champion Ed Clancy and a world class field in a breakthrough performance.
Archbold won the 4000m individual pursuit in a slick 4:26.023, fifth fastest in the 1000m time trial in a personal best 1:04.394 and fifth in the scratch race to claim the overall honours ahead of top Canadian Zachery Bell and Clancy.
In other racing Gemma Dudley is mid-pack after three events in the women's omnium while Simon Van Velthooven (keirin) and Stephanie McKenzie and Henrietta Mitchell (sprint) did not advance into the quarterfinals.
The final day of racing includes the men's sprint, women's keirin, men's team pursuit and completion of the women's omnium.
