Blythe’s inclusion means both the road race and time trial champions will be competing in their home tour, with Alex Dowsett lining up for Movistar.
Also in the GB team for the eight-stage race is new Team Sky signing Tao Geoghegan Hart, fresh off his sixth-place finish at the Tour de l’Avenir, and sprinter Dan McLay, who impressed at his first Tour de France this summer.
Gabriel Cullaigh will ride his second Tour of Britain, having signed a contract to ride for SEG Racing Academy in 2017, while his British Cycling Academy colleagues Oliver Wood and Mark Stewart are also in the squad.
Keith Lambert, Great Britain Cycling Team academy coach, said: “We have been able to name an extremely strong team, with several of our riders having already excelled in various races over the summer. The blend of youth and experience is excellent, and will hopefully prove very effective in what will be an extremely high quality race.”
