Unfortunately, I dont know how to save a path in Google Earth - shame really, because it took ages
The last straight section from the southern most point, is all along the beach promenade, fantastic fun as its soooo fast ...errr, it would be anyway, as I tend to keep to the 10mph speed limit
Its not a circuit, as you can see... a there, and then turn round and do it all again backwards jobby, my speedo generally says ~25 miles at the end
