Formula 1 returns to Istanbul Park in Turkey for only the fourth time in the track's short history and this time it's appearing much earlier in the F1 calendar.

How much difference will this make to the on track action? Well it's much colder than previous years and that may have caught Bridgestone out a little bit. Today will be something of a leap into the unknown for both them and the teams, especially in the cooler first session when the track is less rubbered-in.

Don't hold your breath but there has been a rumoured threat of rain, which, should it come to fruition is bound to mess up the teams plans and further confuse the tyre data.

Free Practice 1 is a 90 minute session and it begins at 10am local time (8am in the UK). We're following Formula 1's live timing screens and watching ITV's online coverage.

A handy track guide is available from Allianz should you need a reminder about corner names and speeds.

Christine will be with us for all of the first session and a most of the second one. We'll do our best to be the eyes and ears of anyone who's unable to watch.

Yell if you're around, won't you? And do let us know any of your early weekend predictions.
