The event is, to put it simply, a six lap motorcross race on a Sanchez against 11 other contestants around a windy figure eight-like track. The challenge of the event lies simply on efficiently negotiating the track's many sharp corners, as well as avoiding being dismounted following a violent landing from a dirt mount jump; the better the player's biking skill, the easier the race will be for the player. Other competitors, on the other hand, may be skillful taking corners, but frequently fall off their bikes following the second jump in the track, giving the player opportunities to lead the pack.
The player must finish first in order to pass the mission. Failing to return to their bike after dismounting for 25 seconds or having the bike destroyed results in mission failure. Completion of Dirt Track in first place is required for 100% completion in GTA San Andreas.
A possible strategy, although not the most advisable, is to kill the most rival competitors possible since most of them will dismount from their bikes in one of the ramps. They can either be run over or shot. However, it's not as simple as just waiting until all rival competitors dismount because there will always be one contestant that does not dismount, therefore when someone escapes from the trap he has to be followed and the rest killed on the other lap.
The reward for completing the mission is $25,000 each time. In addition, the player is award with a BF Injection that spawns in front of the Blackfield Stadium's entrance once the player passes the side-mission the first time.
- It is acceptable to run over contestants that have dismounted following a crash. Killing a contestant by shooting them is also acceptable. However, other contestants seem to have a major health boost and thus can prove difficult to kill, even by explosions.
