The brand offers advanced multisport GPS watches, which will effectively support your daily workouts. Among them is the Forerunner series, but with so many models to choose from, how do you know which one is right for you? To make the decision easier, we've done a side-by-side comparison of two popular models - the Forerunner 745 and Forerunner 945. Check out their key differences!

 
 

Garmin Forerunner 745 and Forerunner 945 - for whom?

Before we dive into comparing these two models, let's start with a brief overview. The Garmin Forerunner 745 and Forerunner 945 are both high-end multisport watches designed for running and triathlon enthusiasts. The Forerunner 745 was released in September 2020 as the successor to the entry-level Forerunner 735XT, while the Forerunner 945 is the successor to the Forerunner 935, which was a lighter alternative to the Garmin Fenix 5x Plus series and later the Garmin Fenix 6 PRO.

Garmin Forerunner 745 and Forerunner 945 - differences in sports features

When comparing the Garmin Forerunner 745 and 945, you'll find that they share many of the same technologies and sports modes. However, there are a few key differences between them. Specifically, the Forerunner 945 boasts some additional features, including golfing features and pre-loaded maps. These include:

 

  • On-screen workout animations;
  • Measurement of breathing frequency during exercise, but only with a compatible accessory;
  • Pairing with Garmin Golf app;
  • Golfing features: preloaded with 43,000 courses worldwide, stroke and distance measurement, digital scorecard, stat tracking, TruSwing™ compatible;
  • Preloaded topographical maps, preloaded road and trail maps;
  • Downloadable cartography support;
  • Outdoor recreation: “Around me” mode and Xero locations;
  • Access to Garmin Cycle Map, a map for cyclists with route mapping.

Although the 745 version doesn't offer these modes, it doesn't mean that the Garmin Forerunner 745 can't navigate a pre-planned route from point A to point B. Keep in mind that on the return trip, the device will only display the direction from which we came during the activity, and it will only show it in a straight line. However, there's an option to access this module through various means, such as the Garmin Connect™ app or a GPX file.

 

Garmin Forerunner sports watches - available variants

It's worth noting the available variants of both Garmin models, as well as what comes included in the set with each sold model.

The Garmin Forerunner 745 offers four colour choices: black, mint, red and white, and is sold in its original packaging with a user manual and a USB charging cable included.

Meanwhile, the Garmin Forerunner 945 has only two variants to choose from. The user can go for: 

 
  • The black watch, which comes with the branded packaging, a user manual and a charging and user data sharing cable.
  • The Triathlon Bundle in blue, which is perfect for beginners and professional athletes preparing for triathlon competitions. It includes an extra set of bands, HRM-Tri™ and HRM-Swim™ monitors, a quick release kit, a charging and user data sharing cable, a user manual and the original box.

Garmin Forerunner 745 or Forerunner 945 - which one to choose?

To sum up, if you're new to the world of running and triathlon, the Garmin Forerunner 745 watch is an excellent choice. On the other hand, for more advanced athletes who spend long hours training in the gym or outdoors, having a long battery life and easy access to maps is crucial. In this case, the Garmin Forerunner 945 is the recommended choice.

Keep in mind that the choice ultimately depends on your individual preferences and expectations from a sports watch. You can explore the extensive selection of Garmin watches on our website.
