Best Garmin Forerunner: Choosing the right watch for each runner

Garmin Forerunner watches have earned their reputation as fantastic options for runners, across multiple price ranges. Here's the rub: Garmin has launched four new models since 2022, from the impressive Forerunner 965 to the mid-range & high-quality Forerunner 255. Deciding which of these great watches to buy is a challenge.

On top of that, you'll find that Garmin still sells most of its last-gen or lower-end Forerunner watches, from the 55 to the 945 LTE. These, too, can be tempting, especially during deals events. But should you buy these and miss out on what the newer Forerunners have to offer?

Below, we've rounded up the best Garmin Forerunner models to help you decide which one is the right fit for all of your running needs.

Garmin Forerunner sensors and features

Garmin watches have a ton of features, and it can be hard to keep track of what each watch can do. So we've poured over the specifications of every main Forerunner model still on the market, to show you what features you'll get (or miss out on) when you choose one!

To summarize, for the latest training features, you'll want to check out the Forerunner 255, 265, 955, or 965, though the 945 LTE has gotten a fair amount of new software sent back its way. You need a 9XX watch for proper maps, or an X65 watch for an AMOLED display and corresponding tricks like Red Shift mode. Generally speaking, the Forerunner 965 has everything on the list except cellular.

Which Garmin Forerunner model should you buy?

As you can see, there's no shortage of Garmin Forerunner models for you to pick from. Without a doubt, most would fall among the best running watches, with the Forerunner 265 and 965 arguably topping the list. 

If you're going to buy one today, I'd strongly argue that you choose the 255, 265, 955, or 965. They're the only Forerunner watches with the most accurate GPS tracking, and the only ones still receiving the latest software tricks trickling down from the Fenix and Epix models — especially the pricier 955 and 965. 

Otherwise, thrifty runners can probably make do with the Forerunner 55. I'd warn that Garmin will probably release a more advanced, affordable Forerunner 65 sometime in 2024, so you may want to wait. 

Still not sure where to start? These are the main factors to take into account:

1. Consider the size

When you're a runner, the size, weight, and thickness make a huge different for comfort, especially for marathoners and up who have to wear one for hours. Forerunners are certainly heavier than your typical fitness tracker, but that applies to some more than others. 

The Forerunner 35, 45, 55, 255S, and 265S all fall into the 36-39g weight class with a 1- or 1.1-inch display size. Many people with smaller wrists will prefer this size, even if it means the display text isn't quite as readable. If that's a concern, get the 265S: its 360x360 AMOLED is so much more readable than the 255S' 218x218 display.

Also, take a look at each Forerunner watch's thickness. The Forerunner 955 (14.4mm) is significantly beefier than the 255 (12.4mm), for instance. That could make even more difference than the weight gap. 

2. AMOLED or MIP

Garmin used memory-in-pixel displays all these years because they save battery life and are more readable in direct sunlight than your typical AMOLED. But Garmin finally transitioned with the 265 and 965 because its battery tech has improved enough to support better visibility while still lasting a long chunk of time. 

That said, the 255 does last significantly longer than the 265, which falls closer to a last-gen Forerunner with its mere 20 hours of GPS battery (same as the Forerunner 55). If that extra 10 GPS hours matters to you, you may want to forego the AMOLED upgrade. 

As for the 965, it's also 11 GPS hours short of the 955, but 31 hours is nothing to sneeze at! And it actually lasts 8 days longer in smartwatch mode, proving it does better while idling. In that case, the only reason to downgrade for the 955 is because of the discount. 

3. Think about the features

As the sensors and features table above shows, Garmin slowly added more and more tricks to its Forerunner watches over time. Even though the Forerunner 55 costs much less than, say, the 745, it shares many of the same tricks. The newer the watch, the more likely it is to have what you need as a runner. 

If I had to pick the Forerunner "essentials" for my running training, this would be my list:

  • Recovery time (55, 245, 255, 265, 645, 745, 945, 955, 965)
  • Training load ratio (255, 265, 745, 945, 955, 965)
  • Elevation tracking (255, 265, 645, 745, 945, 955, 965)
  • Dual-frequency tracking (255, 265, 955, 965)

Aside from more accurate GPS, most of the Garmin Forerunners of the last five years have the "essentials." Other more modern tricks, like wrist-based running dynamics without the Pod, acute and chronic load, nap detection, HRV-based stress data, and Training Readiness are all nice to have, but maybe you can do without them. 

If you actually need full-color maps on your wrist, or the ability to check nearby surroundings without having to download courses first, you'll specifically need the Forerunner 945, 955, or 965. The same goes for other high-end tricks like real-time stamina and Hill Scores for elevation training. 

4. Battery life concerns

You mostly don't have to be too concerned about battery life when choosing a Garmin Forerunner model. The 55, 255, 265S, 945, 955, and 965 all offer at least two weeks of battery life — though that figure won't last if you use a lot of GPS battery. In that case, the 255, 945 LTE, 955, or 965 will do especially well.

You can technically buy the Forerunner 955 Solar to get a further battery life boost, but it's not nearly what you get from an Instinct 2X Solar with its "unlimited" battery life and 145 GPS hours. That watch's solar panel is very efficient, while the 955 Solar panel isn't really worth the $100 extra, in my mind. 

On the lower end, the 245, 645 Music, and 745 all offer seven full days of battery life in smartwatch mode, while the older, budget-friendly Forerunner 35 will give you nine days of juice. Generally speaking, you can expect at least a week of battery life regardless of which model you pick. 

Also, if you buy a watch intending to use the music storage feature, keep in mind that this trick burns through your battery life; expect to lose about two-thirds of your typical capacity, making a 945, 955, or 965 especially useful. 

Garmin Forerunners for everyone

Choosing the best Garmin Forerunner model is only difficult because there are so many good watches to choose between. They're some of the best Garmin smartwatches you can buy. With an extensive catalog of options, it's easy to find a watch that is designed for your lifestyle. Of course, you can also check out all of the other watches the company has to offer to confirm you're making the right choice for your needs.

But in the end, if you want the best Garmin Forerunner for most runners, that's the Garmin Forerunner 265 for features and specs, the 55 for budget quality, or the 965 for everything and the kitchen sink.
