Froome will start his season at the Sun Herald Tour in February after a block of training with Sky coach Tim Kerrison in Australia.
Since racing the Tour Down Under in 2010, Froome has not started his season in January, preferring instead to wait until early February before pinning on a race number.
“It’s an odd decision by Team Sky I have to say,” Cookson said of Froome’s absence from the race, despite coming to Australia.
“It’s not a helpful decision but one understands why these teams sometimes make these decisions. Performance criteria will always overrule other criteria in certain teams and certain cases. It’s a long season and riders need to prepare in the best way, but certainly that was a puzzling decision to me.”
