Well, I'm back. I'm still in one piece but that's because I did take the advice seriously that if I'm not 100% I wasn't going to go/continue. Was feeling OK in the morning so I went, but after a few laps with an instructor something just didn't feel right so I decided to call it a day and went back home. Pretty much on the ropes atm so it was a good idea not to continue.
The weather was bad - rain (OK, this is the UK, nothing to see, move on) but it was also foggy so they had to delay the track opening for a good two hours. Even then, I barely resist the temptation to switch on the rear fogs, it was that bad on one of the sighting laps. During that lap, the highest point of the track almost disappeared into the fog but fortunately it cleared up again.
But OHMYGOD what a track. It's supposed to be one of the most technical tracks in the UK, it has roughly the same amount of runoff as the Nürburgring in a several of places (read: close to nothing - you come off, you meet the armco) and the elevation changes make things even trickier but when you get it right it feels sooooo good. I think it was the first time ever that I didn't feel I needed more power but it also showed that I do need to develop my driving skills quite heavily. Which is why I went there in the first place.
Car-wise, we had the usual bunch of hot hatches, a couple of die hards in Caterhams (including two with no screen or roof), and a couple of proper race cars. Got a little video footage (no on-track one, though) and I'll check in the next few days if any of it is usable.
There's another car trackday there next month, I'm considering to go there again even though I'm not keen on taking the Elise. It's great on the circuit but getting there and back is a huge PITA - thinking driving a completely stripped race car - no sound deadening or anything - 200 miles each way and you're pretty close.
IIRC there are a couple of companies that hire out track cars. I'll have a look at that - a cheap stripped Miata for the day and driving to and from the circuit in something a little more comfy does appeal. Either that, or if I actually manage to get a decentish tow car for my DD, I'll borrow a friend's car trailer and tow the Elise up there.
