Keen to get started on your running journey? Well, you're in luck. Garmin has dropped three new contenders for our best Garmin watch list, and they're all affordably priced and brimming with running-focused features.

The Garmin Forerunner 70, 170 and 170 Music officially release on May 15. You might have pre-ordered one already, but if you're still looking, you also might be weighing up which model is right for you. Do you need the Forerunner 170 Music, or can you save money and opt for the cheaper Garmin Forerunner 70? I break down all the differences below, with a brief bit of context to explain how they compare to other Garmin watches in the range.

Note that I haven't yet had an opportunity to test the watches myself — I've looked at the statistics and feature lists from Garmin's official websites and promotional materials to put together this comparison.

Garmin Forerunner 70 vs Garmin Forerunner 170: Specifications

Garmin Forerunner 70 vs Garmin Forerunner 170: Price

The cheapest watch of the three is the Garmin Forerunner 70, replacing the aging Garmin Forerunner 55 as Garmin's entry-level running watch du jour.

As you can see in our table above, it costs $249.99 / £219.99 / AU$399, while the more feature-rich Forerunner 170 (which replaces the older Garmin Forerunner 165) starts at $299 / £259.99 / AU$479. If you want the Music capabilities, you can pay an extra $50 / £40 / AU$70 for the Forerunner 170 Music.

Garmin Forerunner 70 vs Garmin Forerunner 170: Design

All three watches have a similar design language, and there are few physical differences. There's a single gram of difference in weight between the Garmin Forerunner 70 and its 170 siblings, and all three are only available in a 42.6mm screen size.

They all have the same 1.2-inch AMOLED touchscreen display, and use the same five-button configuration as many of Garmin's other watches, such as the Garmin Fenix 8, which makes it easy to operate the watch even while wearing gloves — perfect for running in all weathers.

Embossed Forerunner logos adorn the bands for all three models, while all three are available in a variety of colors, including Black, Whitestone and two-tone models. Each has at least one unique color option too — the Forerunner 70, for example, is available in a pale-yellow Citron color.

Garmin Forerunner 70 vs Garmin Forerunner 170: Features

Here's where it gets interesting. Each watch has the usual suite of heart rate and fitness-tracking features, such as calories burned, sleep tracking, steps counted and 80 sports profiles. They also all have built-in GPS, Glonass and Galileo satellite network connectivity, to make sure the watch is accurately tracking your runs.

Each one offers Daily Suggested Workouts and personalized training plans via Garmin Coach, the service in the Garmin Connect app. Other training features include advanced metrics perfect for runners such as stride, cadence and elevation, along with Running Power — a metric you may not know about. It's a measure of how much power your body's putting out during a run, measured in mechanical watts.

Garmin works out running power using the watch's motion sensors, GPS and barometer. Using heart rate to determine your performance is considered inferior, because it measures your body's response to the run, not the power of the run itself.

All three watches have wellness features galore, such as sleep tracking, nap detection, Training Readiness and Recovery scores to better plan your training calendar around. Course Planner helps you train at the correct distances, creating routes around your neighborhood, and the Race Predictor feature estimates your time based on a course added to Garmin's database and your historic data.

There are some differences, but they aren't major. The Forerunner 170 appears to have all the training features of the 70, while adding Garmin Pay and Smart Notifications features. Smart Notifications allows you to reply to texts when you're on the move (on Android phones), manage notifications from apps and emails, and screen calls, while Garmin Pay is a virtual wallet on your wrist, and works in a similar way to Apple Pay on one of the best Apple Watches.

These appear to be the only differences, aside from the colorways, between those two watches.

The Forerunner 170 Music adds 4GB of internal memory, allowing you to store songs on your wrist. When connected to Bluetooth headphones, you can listen to music right from your watch, without using your phone as a go-between. Combined with Garmin Pay, this means you can leave your phone at home or in a bag, run while listening to music, and even buy a coffee once you're finished.

Early verdict

The Garmin Forerunner 70 is shaping up to be a pretty great training tool, and if you're not looking for a smartwatch to use for notifications and a digital wallet, this is the model for you.

If you are looking for those things, the Garmin Forerunner 170 or 170 Music is going to be the best choice for you, unless you want to go up in price and opt for a more expensive smartwatch like the Garmin Venu 4.
