Which Garmin Running Watch Should You Buy?

The Garmin Forerunner™ series is Garmin’s primary GPS watch product line for runners and triathletes and is considered the industry standard for running watches. I have been using Garmin watches since 2009, and I recommend them to my coaching clients. While other watches exist and many do a great job, the following watches are among the best running watches available.

Which Garmin should I buy?

This is a common question I receive as a running coach. The correct answer is, “it depends”.

Choosing the right watch depends on what features you would like to have, how you plan to use the watch, and your budget.

Generally speaking, the average runner does not need a high-priced, high-end watch unless you are really into technology and data.

Most entry-level and moderate-level running watches will do everything the average runner will ever need. And do it well.

The best way to use this guide is to determine your budget and look for a watch in that specific price range or just below it. Then look at the features you desire. If a watch does not have the specific feature you want, try looking at the next higher price range.

Most likely, you will find the feature you need without going straight to the top-end watch.

Do not assume you need a high-end running watch. A more expensive watch does not necessarily mean it is more accurate with distance and pace. Garmin has a long history of putting its newest sensors into the entry-level watches, which means a current budget model often outperforms a high-end watch from a few years earlier. That was true when the Forerunner 45 launched and it is still true today with the Forerunner 165.

My feature comparison and product review process

Important: When I do ‘feature comparisons’, I compare watch features based on the information provided by the manufacturer. When I do a ‘review’ for a particular watch, I share my personal experience using the watch. If I have not used the watch, there is no review.

If I review a running watch, I purchase it with my own money. I am sharing my personal experience, and therefore, I am less likely to be influenced by free products from the manufacturer.

If you do not see a detailed review on a certain watch, I either haven’t gotten to it or have not personally purchased it.

The current Garmin lineup for runners

Garmin refreshes this lineup constantly, so treat the model numbers as a snapshot and the tiers as the durable part. Here is how I think about the range as it stands in 2026.

Entry level: Forerunner 165

This is where most runners should start, and it is the watch I recommend more than any other. An AMOLED screen, multi-band GPS, heart rate zones, training readiness, and roughly 11 days of battery, at the price Garmin used to charge for a basic monochrome watch. The Music version adds onboard storage for about $50 more.

The Forerunner 55 sat in this slot before the 165 arrived and has now been discontinued. If you own one, keep running with it. It is still a capable watch, and my detailed review of the Forerunner 55 covers what it does well.

Mid level: Forerunner 265 and 570

These are the workhorses. Watches in this price range get faster satellite connection times, triathlon and multisport modes, onboard music, and the deeper training metrics. The 265 adds Morning Report and comes in a 42 mm size that suits smaller wrists. The 570 is the newer option, with a speaker and microphone and Garmin’s Elevate Gen 5 heart rate sensor.

I wear a 265 myself, and I wrote a detailed review of the Forerunner 265 covering how it holds up in real training.

Premium: Forerunner 965 and 970

If your training goals require more than an average GPS watch, this is the tier. Full color maps, titanium bezels, marathon-ready battery, and in-depth fitness and health analysis. The 970 adds a sapphire crystal, an ECG sensor, and a built-in flashlight. These are helpful and reliable running companions for marathon trainees and serious athletes, but be honest with yourself about whether you will use the extra data.

The fēnix series

The fēnix series is Garmin’s high-end sports watch line. These are sports watches that can be worn with work clothes and look like a regular watch, which is the main reason to pick one over a Forerunner. Compared to the Forerunner watches, they are a little heavier, so make sure you are OK with that on your wrist for a long run.

The fēnix E is the entry point to the line and brings maps and multisport at closer to Forerunner money. The fēnix 8 is the full version, with a dive rating, a flashlight, and a speaker and microphone built in. If you want the rugged looks without the rugged price, start with the E.

Ultra distance: Enduro 3

If your events run past 24 hours, the Enduro 3 is the one built for it, with solar charging and a battery measured in weeks rather than days. Most runners will never need this watch, and that is fine.

What about the older Forerunners?

This page used to compare the Forerunner 35 against the 45, and the 235 against the 245. Those watches have all been discontinued, so those comparisons are no longer useful for anyone shopping today and I have removed them.

If you already own one, none of that changes. I owned a Forerunner 235 for years and it was a great watch. A discontinued Garmin still records your runs perfectly well, and I would not replace a watch that is working just because a new model exists.

My earlier reviews are still online if you are researching a used purchase or want the background: the Forerunner 45 review and the Forerunner 55 review.

Still not sure?

If you want to see every current watch side by side, including COROS and Apple, the Running Watch Finder is the fastest way to narrow it down. You can filter by budget, by running style, and by the specific features you care about, and it shows current pricing and availability.

If you would rather talk it through, that is what coaching is for. Take a look at online run coaching and we can figure out what actually fits your training.

Happy running!
