Two days of activity precede this year's edition of the endurance classic. Wednesday sees four hours of free practice from 15:00 UK time, followed by two hours of qualifying from 21:00 UK - expect the fight for pole in this Wednesday night session unless it rains. On Thursday we see another couple of 2 hour qualifying sessions, at 18:00 and 21:00 UK time, but in recent years teams have switched to race set-up by now. Thursday is worth watching because you never know what'll happen and there is lots to learn, but that shootout for pole will surely be on Wednesday.
