Halvorsen signed for Team Sky after two seasons with the Norwegian continental team Joker Icopal. Halvorsen was due to make his Team Sky debut, in the Tour Down Under, leading his new team in the sprints.[7] However, on 14 January, Halvorsen crashed at the People's Choice Classic, fracturing his hand and thereby ruling him out of the Tour Down Under.[8] On 16 March, he came in second at the Handzame Classic.[9]
