Navigating with GPX

Navigating the route

We had a long think & have decided not to mark the Devon Grit routes with Arrows. Marking a 70km single loop thoroughly is a huge job.  It’s also extremely prone to tampering. It only needs one arrow turned the wrong way or removed to send everyone off course! For example, for the Exmouth Triathlon we organise locally, we checked all the arrows on the 20km bike course at 6.30am on the day of the race. By 8am, when the first riders arrived, a crucial arrow had been removed by someone & a number of riders went off course.

Self Navigation

Devon Grit is self-nav.  We’ve decided to put our time & effort into producing excellent, accurate GPXs & course descriptions. And to providing technical support to make sure everyone arrives at the start line with the correct route loaded on their device of choice!

Almost all keen cyclists now have a Garmin or similar device suitable for navigating a route. If you don’t have one they are available from as little as £100 or less (eg Garmin Edge 130 GPS Bike Computer is £99 on Amazon at time of writing). In fact if you’re into riding off road you really should get a bike computer as it will open up so much new terrain to you! Alternatively you can buy a phone bracket for your bike (approx £20) and use your phone to navigate the route using

We’ll be publishing the GPX’s for upload to Garmin, Wahoo or similar devices.

We’ll also publish the course maps on Komoot, which works well if don’t have a Garmin or similar unit & plan to use your phone for navigation. If you’re planning to do this we recommend you use your phone in Airplane mode with the map pre-downloaded to minimise battery use. Contrary to what a lot of people think, the GPS functionality in your phone does not need a mobile signal.

How to get a GPX onto your Garmin device

Log into Garmin Connect. Under Training on the left menu select ‘Courses’. Then click Import (bottom right of the white box) to import the course & give it a name.

Once the course is imported, select it & send to device.

If you have trouble with syncing sending to device (and some people do), you can instead download the .FIT file to the desktop of your computer. Then connect your device to your computer with a cable & use file manager to copy the FIT file across onto your Garmin in the Garmin/Activities folder

If you own a Wahoo the process is very similar. If in doubt have a look at this video

Phone back-up

If you’re navigating using a Garmin watch or one of the smaller Garmins, such as the Garmin 820, we recommend you also put the GPX on your phone. That way if you inadvertently miss a turning you can see at a glance exactly where you are on a full sized map on your phone. Here are two apps we recommend.

Viewranger App

Just install the FREE Viewranger app on your phone.

Click the search icon at the top. Next tap the icon on the left and select Routes

Then type in the route code (which we’ll release the week before the race)  to download the correct route. Viewranger’s own landscape maps are quite good or for a small charge you can download the Ordnance Survey tiles & have the full OS map on your phone!


As already mentioned. Just install the Komoot app on your phone and then load the correct route. Details will be added to this section.

You can buy the Devon pack for Komoot for £8.99. This gives you offline maps of the whole of Devon & also adds turn by turn voice to the navigation.
