The SAR events are time trials and hill climbs without any head to head racing. I did Interlaken a few years ago: you get 3 runs and I think the airfield loop is about 4km. So a whole day for 12km racing. Really not worth it.

Anneau du Rhin (just North of Basel in Germany) has a few track days. I did a Porsche Club France event about 18 months ago where we had unrestricted track time for the whole day. It was great but costly: 2 tanks fuel, 4 tyres, 4 disks, 4 pads... Its a good circuit with a mix of slow and fast bends and a couple of good series of bends and tricky/double apexes, plus pretty wide run offs except for one section. A standard 911 will get to about 200kmph on the straight with a good exit from the preceding 180 degree bend.

The SAR trainings at Hockenheim (short circuit) are great to learn technique as you learn each bend one at a time for the first 1.5 days, but there is only about 60 mins of heavily regulated track time on the afternoon of the second day, and the track time was full of gits who thought it was a real F1 race so wouldnt let you overtake safely even if you were faster. I was in a Boxster and spent 20 mins glued to the back of 911s in the bends, but without quite the oomph to get by on the straight. And, since its 1km long and you top 200kph at the end, Im not experienced enough to risk an overtake on the limit of braking especially when the guy in front is a crap driver just with more HP.

I hear Dijon is quite narrow.
