The MapMyRun website enables users to map out routes for physical fitness activities, such as running or bike riding. You can export maps as a GPS Exchange Format (GPX) file, which you can download to some Garmin GPS receivers. GPX files are not compatible with all Garmin GPS receivers; the Garmin Forerunner line of GPS watches for runners does not support GPX, for example. Garmin Edge receivers, which are used by bike riders, can import files exported from MapMyRun. Warnings Writer Bio
