The 23-year-old will compete in Australia's Tour Down Under from January 14-22, where he will be joined by Team Sky teammates and fellow Welshmen Geraint Thomas and Luke Rowe.
Doull, who won team pursuit gold at the Rio Olympic Games last year, joined Team Sky ahead of the 2017 season from Team Wiggins, and insists a good performance in Belgium is his main target for the new campaign.
But first comes the race in Australia, and it's one that Doull admits will really test his ability.
"My big aim for the year is that big week in April in the Tour of Flanders," he said.
"I've raced on the road to a decent level before, but never anything world tour.
"I'm looking forward to getting my first proper race with Sky under my belt and doing my job, and trying to put a good performance in for the team."
Following in the footsteps of his Welsh teammates, Doull knows only too well how beneficial competing in the Tour Down Under will be for his career.
"Speaking to people like Luke and Geraint, they say it's a really good way to start your year," he said.
"You have to come out to Australia quite early, do a couple of weeks of training then obviously straight into the first world tour race of the year.
"It's going to be good to get a good one under my belt quite early. It's a nice way of doing it as well, getting away from the cold and the winter of Cardiff and escaping to the sun and getting a consistent block of work done.
"There's no distractions and no problems like ice on the road."
