Original Circuits
Dreamt up by the Gran Turismo team, these circuits are generally more in more outlandish locations and less likely to meet real health and safety requirements than the real-world circuits. Most are in fictional locations, donated in the list with 'PDI' where the track location would be; but some are fictional tracks in real locations. The vast majority can also be run in reverse.

Notes:
Grindelwald
Grindelwald, Switzerland
Full Circuit
GT2
2.15 miles
Set time - day
Notes: unlike the other two original courses based in the Swiss Alps, Eiger Nordwand and Matterhorn, Grindelwald's layout is made up of real roads, making it almost more akin to a city course than an original. It's layout can be quite easily seen looking at an aerial map of Grindelwald. It is also located around 5 miles from the location of the Eiger Nordwand tracks, not to mention both not being far from the location of Forza 4's Bernese Alps track. Strange that a country so hateful towards cars would feature so copiously in racing games (not that I have anything against the Swiss).
High Speed Ring
PDI
Full Circuit
GT1, GT2, GT4, TT, GT5P, GT5, GT6
2.49 miles
Set time - 16:10
Variable weather (listed as separate track)
Notes: this track's layout was loosely based on the original layout of Fuji Speedway, a track that actually made it to the series in GT4. Despite this, HSR remained.
