Once a upon a time this was a Sprint venue, but in a much shorter guise, till it got knobbled by the MOD.
Some words of advice.
It is very wide and undulating, so is a pretty exciting venue.
Mostly made up of smooth concrete which is extemely abrasive and will wreck any track orientated tyres very quickly.
If its dry on the day the venue will be very dusty, making the short tarmac sections pretty slippery.
Lastly, the track is very wide, but there is absolutely no run off anywhere. If you dont disappear down one of the deep trenches then you will probably hit one of the very large concrete tank traps. Dont want to be a killjoy, but have seen some nasty smashes at this venue.
Have fun
