As is often the case at the Tour Down Under, Old Willunga Hill saw the most explosive racing of the first WorldTour event of the year.

After selections were made only Richie Porte (BMC) and Sergio Henao (Sky) remained at the front of the race, and Porte soon left his former teammate behind.

Riding for his new squad BMC Racing, the Australian soloed to the finish to move up to second overall ahead of the final stage.

Porte won the same stage last year and finished second overall then, too. Rohan Dennis, now a teammate of Porte’s, won the overall in 2015 but has been off the pace this year.

Simon Gerrans retained the overall lead and, barring disaster on stage six’s criterium, he should hold on for his fourth general classification victory.

The Tour Down Under concludes on Sunday, January 24, bringing to a close the opening race of the 2016 UCI WorldTour Calendar.
