How to fix GPX files in Garmin BaseCamp
If you’ve ran long enough, I’m sure you can find a few GPX files with whacky points. Maybe you couldn’t wait for the pesky Garmin watch to have enough satellite fixes before starting your run. Or maybe you forget to stop your watch and drove off? Or maybe your elevation shows a 60,000ft climb within the first 200ft of your activity? Believe it or not, it’s an easy fix that will only take a few minutes. I will show you how to fix GPX files that are broken or corrupt.
This tutorial is for the Mac version of the software. If you haven’t yet, download and install Garmin BaseCamp here.
