Free Practice is back on our schedules with the drivers set to do the business around the Korean International Circuit. It's a traditionally quite dirty track with very little running across the rest of the year, so expect the big guns to wait it out a little while those desperate for mileage clean up the tarmac for them. Otherwise, it's a matter of seeing who is the closest challenger to Red Bull this time, and searching for any chink in their armour, whilst enjoying the inter-team battles through the rest of the field.
