The Dutchman was last to set off for his time-trial and he managed to unseat BMC Racing Team’s Rohan Dennis, who held on to his lead for most of the day, at the completion of the route.
He beat Dennis by two seconds with a winning time of 12:02, with the Australian finishing mere split seconds faster than Lotto Soudal’s Victor Campenaerts (Belgium) in third.
Dumoulin was happy with the start to the tour. “This is all I wished for – the win and a lot of time on the other GC riders. This was a perfect start for me.
“I knew I felt good in the last few days, but we still had to see how the race went.”
The technical course suited him on the day, Dumoulin added. “The course was perfect for me. It was very technical and I’m good on corners on the time-trial bike.
“It was full gas, recover, full gas, recover, so it was perfect for me.”
