Here’s mine: http://www.gmap-pedometer.com/?r=5764772
I wanted to include a few sections that I know from driving the area, such as the fast first corner, which is a downhill sweep onto the roundabout, them uphill sweep off it, quickly followed by a hairpin as a ‘true’ first corner. I originally wanted this slightly further along the road, but had to shorten it to be within the 8km limit. It the drops down again to the roundabout before heading into slightly more residential roads. There’s a kink on this straight before a 90 degree left, which leads into a nice downhill run, with a fast left and faster right. The next corner is a little sharper to ensure that every time the circuit encounters a roundabout, they are treated differently. The next straight has a fast sweep in it, and then reaches the very fast, uphill corkscrew. The following corner is double-apex, and the final corners are a slow chicane to break up the long straights either side. The track is very high speed, with 4 straights over 1km in length, but all have bends/kinks to make them more interesting for drivers, and visually for TV viewers. The only real problem is the roads being a bit narrow between the 2nd and 3rd km markers.
Around, through and across a lake. It is 5.1271 km km long, hence would do about 60 laps to complete correct race distance. It is also a relatively fast and flowing circuit. The start-finish line is the straight on Albert Street.
