While the race is traditionally one for the puncheurs, the Dimension Data climber senses opportunity on the penultimate stage up the 5.7km, 10.5 per cent climb.
“My approach to Green Mountain will be to be relaxed and let the legs do the talking," the 23-year-old said.
"It’s a super steep climb so you’re not going to be able to hide, you’re not going to be canny, you’ve just got to have faith in the training and the ability that you’ve done before.
"It’s the first mountain-top finish of the year and my shape over the last two or three weeks has really started to pick up so I’m excited."

But O'Connor also has deeper ambitions for the race.
"I’m not going to shy away from the fact that I’d love to try and aim for the young rider's jersey and then see what kind of placing we can get from there. So yeah, I’m ready to try.”
His team also has Ryan Gibbons and Enrico Gasparotto for other options that might pop-up during the six-stage tour.
O'Connor said in a recent newsletter he will focus on Giro redemption in 2019 after crashing out of the race and the top 10 overall on Stage 19.
"Crashing out of the Giro d’Italia in the top 10 still sucks," he wrote. "I wanted to finish and get that number, but being up there in my first Grand Tour is something I’ll take with me into the future.
"This season is all about the Giro d’Italia again. Can we get redemption? I'll be looking to do the same kind of result but finish it this time."
