TomTom Spark 3: Route exploration

The main reason you'd consider upgrading from the Spark to the Spark 3 is the new route exploration feature. This basically means you can now go out on a big run and the route will be mapped out on the watch screen, helping you navigate your way home a little easier. You can now add routes to the watch as well, which is handy if you want to run an approximate distance or just freshen up your running routes. It's a feature that usually crops up on more expensive sports watches, so it's definitely a positive to see it appear on the Spark 3.
The reason you can do this on the Spark 3 is because TomTom has now included a compass, which means unfortunately you're not going to see this feature crop up on the older Spark.
If you just want to get out running and view your route, you'll need to calibrate the compass first, which is done in the sensors section inside the watch settings. It requires rotating the module in different directions, and we'd suggest taking the module out of the strap to do this as it didn't calibrate when we left it in. Then you can start tracking a run as normal and you'll now be able to skip to a screen where you can an overview screen and a zoomed-in screen to view your route. After a few runs and doing my best to get lost, it did get me back to my starting point.

The more interesting application is the ability to upload routes. TomTom supports the ability to upload GPX files, the most common GPS data file format. To get one uploaded to the Spark 3, a quick Google search will quickly find you what you need, but a good place to start is MapMyRun. Here you can easily create routes or search routes and download them to your computer. Then you'll need to upload them through the TomTom MySport web app. It's a pretty painless process and then you're good to go exploring. When you start to track a run, you can now select a trail. It's as easy as that and it's worked perfectly fine for us on the few runs we've tried it with.
According to TomTom, you're not required to calibrate the compass before activity but the Spark 3 will offer to calibrate if it considers it's needed. You can still calibrate whenever you wish as well.
Will it be enough to convince Spark owners to upgrade? That really depends on how much you value the option to mix up your running routes. We certainly enjoyed having it and it'd definitely come in handy taking the watch abroad or into unknown territory. We think it's a great addition, and it works well.vedere di piu watch replica e Hublot Classic Fusion
