Yep, a couple of times, its a great circuit with a real mix of elevations and turns.
The first half of the circuit is quite tricky and it really flows if you get used to it and get it right!! Get this bit wrong and it'll take a while to get the rest of the track right.
There's also a really long straight at the end of the circuit that allows you to have a great rest.
If the weather's good, which it should be, you'll love it.
