Design a good, challenging race track in any city!

Not surprisingly, Stage 2 starts out where Stage 1 ended. Median time to cover it (at normal speeds) is around 20 minutes. On rainy days, this road is closed, since the road hugs the mountain and there are lots of loose rocks that tend to fall on the tarmac during heavy rainfall. Longest straight is at the start, which is about 400 metres long, and it's a track perfect for smaller cars with lots of power... there's very steep ups and downs, although the general trend of the road is rising from 31 metres above sea level (start) to about 1,100 metres asl (finish) and some curves are extra wide... perfect for sliding around.

Vuelta de Gran Canaria, Stage 2



Vuelta de Gran Canaria Stage 3



This stage starts out still in ascent, from about 1,100 metres asl and ends up at close to 1,300, though midway through the stage you reach 1,800 metres. Early in the stage there's a series of long, ascending curves which will allow to reach high speeds, but at around the 4 km. mark there's a succession of quick, short, ascending curves... followed by many ascending and descending roads where the sea is lost to the eye in many parts. The stage's last sector is a series of descending curves, still very tight. The stage ends at the start of a downward slope that marks teh start of the 4th stage.

Vuelta de Gran Canaria, Stage 4



Final stage is probably the quickest. It's mostly a downward slopes with not as many curves as the previous stages. Starts at around 1,300 metres asl and ends at the Playa de Amadores, at sea level.

The first sector takes you through a few towns where the narrow roads still are the norm. These give way to wider, centre-line-including roads and in some cases wide enough to fit three lines of cars. There's long straights that are sure to hit the rev-limiter in smaller cars though, in true European fashion, they're littered with annoying roundabouts to slow you down and trigger surprise skids.

Halfway through the stage there's a sharp left turn after a roundabout that takes you to the highway-ish part, starting out with mountain-hugging road, followed by a wide 2-lane highway with a couple of very nicely-made tunnels, contrasting perfectly with the start of this stage as well as the previous stages. After the 2nd tunnel we briefly go into a bit of curves again, but they're shot-lived, as the end of the stage is close by. The stage's exit, however, is easy to miss... it's a sharp right turn that ends up in a roundabout.

This is the only thread on this topic, I could find...

Anyway, I made a San Francisco track.
