King of the ovals: Achievement PSN of Gran Turismo Sport

As of now, there is only one truly oval track in the game, the Northern Isle Speedway. Its length is half a mile, so you need to do about 1,000 laps on this one. A lap takes about fifteen seconds, so a total of about four hours on this track should be enough for this trophy. This track is also featured as one of the regular and recurring online-races, so on your way to all those wins, you most likely will play on this track quite a bit.
