The 2018 Tour Down Under was spread across six stages, each throwing up different challenges for the riders. The race will ran from January 13 to 21 and was won by Daryl Impey.
The South African, riding for the Michelton-Scott team, won the race by way of a countback over home crowd favourite Richie Porte (BMC Racing), who almost claimed the prize during Stage 5 up Willunga Hill. Instead, the two finished with exactly the same time at the end of the six days with neither able to get among the time bonuses on the final stage around Adelaide.
The podium was rounded out by Tom-Jelte Slagter (Team Dimension Data), with the Dutchman finishing 16 seconds behind.
The mountain honours were claimed by Nicholas Dlamini (Dimension Data), while the sprinter’s jersey was won by Slovakian Peter Sagan of Team Bora–Hansgrohe.
