This has got to be the Tourist Trophy not any other variation so 1 each season. 1 Lap qualifying and then 4 laps. Don't forget to pit after 2 laps and don't speed in the pit lane (60 km/h) you will get disqualified. You can quit out to main menu at any point and then when you go back on career you can resume from the last checkpoint. If you are having trouble with the AI you can quit out reload and eventually the AI will mess up and crash giving you a chance to beat them. Supersport is the best option as they are more forgiving than the superbikes. I used M Dunlop's R6 on easy and won 3 on the trot. It will only show you split times if you are not winning if you are winning then no times display as you go through each section checkpoint.
