Constitution Road in Windsor coming out of the city on Lutwyche Road just turn left just before the Office Works at Windsor.
Its a great shortcut to get to Days Road at the Grange.
Its got three hairpin turns and a straight the hairpins are all uphill and the straight is downhill.
Just be careful on the hairpins as there are usually cars parked everywhere on both sides of the road and pedestrians crossing at peak hour.
Apart from that is a brilliant little run for an MX5.
