American Fugitive

The jump has to complete to qualify. Distances are shown when you've landed the jump. It's possible on many jumps, the below is where I did mine.

Drive a cop car or a Kamara to the lake which borders the Endtimes outdoor supply shop. Head around going west until you find the stunt jump which heads over the lake. Now, take a huge run up and floor it. If you successfully land the jump by the Beanz coffee shop, your achievement will unlock.
