Tsukuba 9 Hours Endurance (GT4)

The Tsukuba 9 Hours Endurance is an endurance event in Gran Turismo 4. The race lasts for nine hours around the compact Tsukuba Circuit training course. Only cars with normal or sports tires are eligible to enter this race.
The aim of this endurance race, rather than to complete a set number of laps in the fastest time, is to complete the most complete laps in the nine-hour period. The race ends at the end of the first lap completed after the checkered flag falls (9 hours + 1 lap).
Winning the Tsukuba 9h Endurance awards the player a Nissan CALSONIC SKYLINE GT-R Race Car '93.
The event, which takes 9 hours to complete in A-Spec mode can be won in just 3 hours if the player uses B-Spec. Due to the limitations of the PS2, although the event takes place over the course of 9 hours real-time, neither the weather nor the time of day changes during the race.
==Possible Opponents==
This chart lists all possible AI opponents that can appear in this event. The "Lap Interval" column shows how many laps the opponent will stay out on the track before pitting in.
Be careful of the Lotus Elise. Although it has the lowest horsepower of the typical opponents, it is also the lightest so its handling is incredible. It can also go many laps without having to pit in.
