On an awesome scale of 1 being Abu Dhabi or Phoenix and 10 being the Nordschleife or the old Spa, then COTA is about 3 in my book.
Harsh.
It's probably lacking a bit of kitty-litter in some key places - but it's a real challenge....... compounded by some decent elevation changes - and a genuinely enthusiastic crowd.
If I didn't have to pay Lloyds for the privellidge of having a roof over my head - then that'd be the first non European race I'd head to.
I bet a race in the wet around there would be off the scale........
