Before loading the track, be sure to have a rival with a very bad time. Once the track loaded, go in Aids tab and set everything but Steering to the most left setting. Steering can stay to Normal. Now start the race, and beat the rival with the minimal possible gap you can, so that the game will set the next rival to an easy time to beat, and so on until you beat 10 rivals.
