Ive heard that not all GPSs will choose the same route. Hows that going to work?
Your GPS will only get you to the start of each leg, and you’ll have a time to leave that point, then you’ll follow instructions to the checkpoint. We’ve built in enough time to reach the start of each leg that slightly different courses won’t matter. The distance traveled while doing those instructions will be the same for everyone and how closely you follow those instructions will determine your score.
