Gallery: Formula 1's winter wondertracks

It's just 48 days to go until pre-season testing kicks off in Barcelona.

The Circuit de Catalunya is currently resting under its winter blanket, but one hopes that by the time mid-February comes around, its tarmac will be rid of all snow - contrary to last year.

However, Barcelona isn't the only circuit covered in white, so we put together a gallery of other venues enjoying a slumberous period of hibernation.
