The race this year was extended from four to five stages with an individual time-trial added on the final day.
Team sport director Roger Hammond said the Slovenian race formed an important part of their season.
“It is part of Mark’s build-up to the Tour de France,” he said. “Essentially that is our objective in Slovenia.
“We want to build towards the Tour [de France] by going through our race processes and finding our rhythm.”
The race will comprise two opening sprint stages, followed by two puncher races, before the fifth and final 21km individual time-trial.
