Cheers for the comments guys
This was an organised event through circuit days & I'd deffo recommend them (
http://circuit-days.co.uk/tracks.asp)
Costs wise for me leaving Central Scotland down to the Eurotunnel, Calais to Spa, trip to the ring, track day (9am-6pm) & then Spa to back to Central Scotland (1700 miles) was around 5 tanks of fuel. (£300)
The Eurotunnel was £77 return
Hotels for 3 nights about £300
Then about £60 for your meals for 4 days
Then the track day was £259
So your prob looking around £1k, obviously the closer you stay to the ferry port/Eurotunnel the less it will cost you on fuel
Tyres still hav tread on them too after over 8000 miles & the track action
