Most smartphones and tablet computers are GPS-enabled. With the right app they can be used as a navigational aid. To do this, download the GPX file from the route page and import it to your device. How this is done depends on the app you’re using. Your app will determine your choice of base maps.
If you want a really simple phone app for following a GPX track, Bike GPX is good, free and available for both Android and iPhone.
Whichever app you use, it’s best to download the base maps onto your device before you go, in case you are in a place with no phone service. GPS can drain batteries fast, so it’s worth taking a paper map as a backup, at least until you get an idea of how long your device’s battery will last when being used for GPS navigation.
Phone navigation apps are great but it’s probably safest to carry a paper map and/or the turn-by-turn route instructions supplied with each ride as well, or to use a dedicated GPS navigation device like a Garmin or a Wahoo.
When following a route on a phone, a device like a Garmin, or printed turb-by-turn instructions, try to remember to look up and look around to get a sense of the lie of the land as you pass through. To take your navigation to the next level, check out Tristan Gooley’s books and website.
