Garmin Forerunner 45 – Two Sizes

The Garmin Forerunner 45 is released in two sizes, 45 and 45S, which have 42 mm and 39 mm screen sizes respectively. Besides this, they are completely identical. The Watch is an upgrade to the earlier and also budget-friendly Garmin Forerunner 35. With a new look, rounded screen, and color display, they look more like a traditional watch. It still remains a solid fitness tracker in particular for runners.

Garmin Forerunner 45 With a New User-Friendly Menu System

One of the major and most important changes compared to the Garmin Forerunner 35 is that the Forerunner 45 has got a new menu system, and at the same time has added from 4 physical buttons to 5 physical buttons. The menu system is now the same as used in the much more expensive Garmin watches. The extra button and the new layout make a huge positive difference. It is far more intuitive and very user-friendly.

Garmin Forerunner 45s is compatible with your smartphone

To get started using the Garmin Forerunner 45, you download the Garmin Connect app to your smartphone. When you open the app, you first need to create a Garmin account, and then you will be guided step by step through the setup of the Garmin Forerunner 45, which is easy and straightforward. The Forerunner has features for your compatible smartphone by using the Garmin Connect app.

The Garmin Connect app is the place to set up your watch, but this is also where you get all the training and activity data that the Garmin Forerunner 45 collects. Activity transfers, interaction with social media, and training downloads are also included here.

Structure Your Running Training With Garmin Forerunner 45s

A great feature of the Garmin Forerunner 45, and something that sets the watch apart from other smartwatches is the ability to transfer training sessions directly to the watch. And subsequently, be guided through the run – while you run.

If you already follow a training program, you can easily create the individual training sessions in Garmin Connect and transfer them to Garmin Forerunner 45, thereby optimizing your training options.

Interval-based training sessions are good to follow at least once in a while to improve your performance. Garmin’s training planner works excellently here. Forerunner 45 ensures that you run the right distance/time and at the right pace – and you do not have to keep track of times, pace, etc. It gives greater freedom to the actual execution of the training.

Along the way when you run, the watch will alert you when there are 5 seconds until the next “step” begins. The Forerunner 45 runs a beeping countdown of 5 seconds. The screen then shows what you need to do now. It’s a smart feature that works really well!

In that way, you are sure to run the intervals at the selected pace. So, you avoid completely having to keep track of when there is a break and when to run. You really just have to do what the Watch says.

Garmin Forerunner 45s Run/Go function – Excellent for Newbies

If you are a complete beginner in running, a large part of your training should consist of walking. You can with benefit switch between running and walking on your training route. Under “alarms” on Forerunner 45, you will find a smart running/walking function, where you can enter how long you want to run and how long you want to walk.

When you then start your training, the watch will vibrate and beep when it is time to switch over to running or walking.

Garmin Coach – FREE Running Programs Adapted To Your Activity Level

If you find it too demanding to create training- and running programs yourself, then Garmin has a solution with their GARMIN COACH feature. As I see it, Garmin Coach will be great for the beginner who wants to get started with running training, or more experienced runners who want more structure in the training, and then focus more on the actual execution in practice. Garmin has a team with some of the world’s best running trainers, who have designed a series of training programs aimed at the 5 km, 10 km, and half marathons. And you can choose to follow them.

Forerunner 45s Garmin Coach – In action

When you start the first training session, you will be asked to perform a short “Benchmark Run” to give the Garmin Coach a hint about your current shape. Based on this run and your entered information, Garmin Coach then generates an individual training program for you.

The individual adaptation continues. Because after each training session, you have the opportunity to assess the degree of difficulty of the completed run, while Garmin simultaneously assesses how you managed it – and how your shape develops. Based on this, the progression of the training program will be continuously adjusted so it’s neither too easy nor too hard but matches your level.

It’s primarily aimed at newbies or exerciser who wants to track their running training and daily activities without spending a fortune.

The watch is very user-friendly, and it can do far more than expected from a watch at this price level. So, I think the vast majority of runners actually will have their needs met with the Garmin Forerunner 45.

The Garmin Forerunner 45 is an affordable running watch that is especially recommended for the beginner and exerciser who wants a relatively simple run.
