How to find out if a TD is on at Silverstone May 31?

[Anatol]

Slightly odd question - my stepdad has booked his son on a Caterham sportscars circuit experience at Silverstone on May 31st. He's done the day himself and doesn't want to do it again, but fancies taking his own car if there's a standard TD ongoing on the circuit on the same day.

Silverstone's website doesn't have a calendar of who is running what on what day as far as I can tell...

Is there a way (short of ringing them Monday morning) to find out if any TD organiser has booked a TD to run on that date?

TIA

I had a look on trackdays.co.uk that resell a lot of other companies and couldn't find anything. You could just ring silverstone and ask.
