Great event help

What about some kind of elimination races, though it would depend on the number of people that show up. Just need to pick check points on the map and last person there is disqualified. Examples:

Race 1: Vehicle(roadtrain) point A to B [1 person eliminated]
Race 2: Vehicle(bicycles) point A to B [2 people now eliminated]
Race 3: Vehicle(running) point A to B [3 people now eliminated]
Race 4: Vehicle(dinghy) point A to B [4 people now eliminated]

and so on until only one man left. Can work in teams as well so that the best team wins.
