So I have taken to creating some races and feel that I have a couple of good ones for play. One is simply a looong trek around the entire southern half of the world and the other is a 5 minute mega jump fest, that is quite challenging, but really fun and fast. Both offer max payouts, the one titled "Jumping Bridges" offering 1650RP even when done solo.
This is my first endevour at race creating in GTA:O, but I think I did ok. Especially Jumping Bridges. It really is a blast and isnt a 30sec 3 jump grind map, but a BIG air proper race.
