As the race begins, instead of going forward, turn around and go straight. You will be jumping off a cliff, but if you can land your car successfully you will be on your way. Keep driving straight into the town. Take a right turn at the first right you see. If you have already done the race you should know where to go. Follow the road and take another right. You will then be driving across a small bridge. Turn left on the small dirt road and park your car at the end of the bridge. Since you are allowed only 25 seconds out of your car, you must do this quickly. Once out of your car, run to the middle of the bridge. Enable the "Spawn Rhino" code, which should block the bridge. Do this as many times as desired, but be aware that the other cars will show up sometime around three minutes. When the cars appear, make sure to have the rocket launcher out before getting in your car. When the cars show up, they will drive into the creek/river. Quickly get out of your car and fire multiple rockets at them. Do this very quickly. You can then complete the race with no competitors. Additionally, before the race starts, enable the "Flying cars" code. Go to the race. Immediately at the start of the race, all cars will floor it and will fly off the cliff. This gives you as much time as needed to complete the race. Make sure you go drive slow so that you also do not fly off. About six minutes are required to complete the race.
