Mark Cavendish is set to race in the 2018 Tour de Yorkshire.
The 32-year-old Team Dimension Data rider, winner of 30 Tour de France stages, is due to attend Tuesday's route announcement in Halifax.
The Tour de Yorkshire has been expanded to four days for 2018, with the women's race to be staged over two days.
Barnsley, Beverley, Doncaster, Halifax, Leeds, Ilkley, Richmond and Scarborough have been named as the locations for starts and finishes of the stages, with the full route to be unveiled at 11am.
The Tour de Yorkshire is a legacy event of the 2014 Tour de France Grand Depart, when Manxman Cavendish was favourite to win the opening stage in his mother's home town of Harrogate, only to crash within sight of the finish line.
Yorkshire is due to host the 2019 World Road Championships, when Harrogate will serve as the main hub for race finishes.

British rider Mark Cavendish claimed his fourth stage win of the 2016 Tour de France – and 30th of his stellar career – with a sprint victory in Villars-les-Dombes.
Cavendish enjoyed his best ever first week of Le Tour with victories on stages one, four and six, and the Dimension Data sprinter proved he still has strong form after coming through the first mountain stages.

Sir Bradley Wiggins will reunite with Mark Cavendish to race at this year's Six Day London event in October.
Wiggins, who had previously suggested he would retire after this summer's Olympics in Rio, but has signed up to compete alongside Cavendish in what he calls "the double act everyone wants to see".
The pair teamed up to win Madison gold at the world track championships in March and will be back at the capital's Lee Valley VeloPark for the first time since that triumph.
Wiggins, who will be aiming for a fifth gold medal and British record eighth podium appearance if selected for Rio, said: "It's going to be great. This has got to be the double act everyone wants to see isn't it?
"Winning the Madison at the Worlds was incredible and this might well be the last chance that people get to see us together.
"I was gutted not to be able to ride it last year, but this year the timing just fits so I'm hoping it will be a great way to celebrate a successful fifth Olympic Games, back in London."
Sprint ace Cavendish added: "One of the first things I said to Brad after we won the Madison on the track in London was 'we have to do London Six Day together'.
"The Six Day experience is something else - the atmosphere will be right up there with the World Championships, the music's loud and the racing is brutal. It'll be great to team up with Brad again and we'll be going for the win.
Mark Cavendish has made himself available for selection for Great Britain's Olympic track cycling team.
The 30-year-old from the Isle of Man took time to reflect on his Track Cycling World Championships performance, where he placed sixth in the six-discipline omnium earlier this month and won gold in the non-Olympic Madison alongside Sir Bradley Wiggins.
And Cavendish, who has twice suffered Olympic disappointment, has put himself forward to be considered for August's Games in Rio after speaking to British Cycling technical director Shane Sutton.
Sutton said: "I spoke to him earlier this week on what his intentions were and his intentions are to carry on with the project.
"Given his performance at the worlds, he's decided that he wants to be put forward for selection at the Games.
"We just wanted him to go away and see where he was at. He's decided he feels he's done enough to warrant putting himself forward and he believes he can still win."
The rider in the omnium must also be able to slot into the four-rider, four-kilometres team pursuit squad as there are three rounds of competition in close proximity.
The team event takes priority over the omnium, which can be something of a lottery, and Cavendish must be able to compete at gold medal-winning, world record-breaking pace.
