These races require you to race on an ATV or a dirt bike and in a jeep. You do not need a vehicle to enter these races as you will be given one automatically. It is random whether you get an ATV or a bike so if you don’t want to use one, you can replay the race to get the other.
You can knock opponents off their respective vehicles by ramming them so you can use that to your advantage. Do not try and attack them or you will be disqualified. Use slipstreams to gain a jump on your competition too. Get right behind them and then swing out past them. Also be aware that they can get in your slipstream so weave in and out to prevent this if they are right on your tail,
Unlike the sea races where all the races are available from the start, you will unlock further races upon reaching the podium of the previous race for these ones. Remember that Franklin will always have the advantage over Michael and Trevor for these races because of his special ability.
