The 965 is the flagship watch built for triathletes, ultra-runners, and data-obsessed athletes who demand the best. It combines all of Garmin’s most advanced training features with a striking, premium build.

Pros & Cons:
- Pros: Unbeatable, vibrant display; best-in-class GPS accuracy; full onboard mapping; huge battery life (up to 23 days in smartwatch mode).

Garmin Forerunner 265: The Runner’s Favourite

The 265 hits the ideal balance between modern features and mid-range pricing. It inherits many advanced tools from the 965 and replaces the older, dimmer screen of its predecessor.

Pros & Cons:

Best For: The committed runner upgrading from a basic model who wants a bright screen and access to advanced insights like Training Readiness without needing full onboard maps.

Garmin Forerunner 55: The Runner’s Starter Pack

The 55 is the simplest, most reliable, and most affordable dedicated running watch in the current lineup. It sticks to the basics but does them perfectly.

Best For: The pure beginner, the casual runner, or someone who wants a simple, no-fuss watch that tracks mileage, pace, and suggests workouts.

Five Garmin Forerunner running watches arranged side-by-side

Customer Opinion

I have not tested all five of these watches personally, but here is what consumers and highly-rated tech reviewers generally say about each product:

Forerunner 965: Customers consistently praise the AMOLED screen and the accuracy of the maps, stating it feels like a significant upgrade from previous generations. The main consumer complaint is that the price tag is very high for non-professional athletes.
Forerunner 265: This is often called the “perfect compromise.” Users love getting the bright screen and the crucial Training Readiness feature at a middle-tier price. The main drawback cited is that the battery life is merely “good,” not “epic,” compared to the older 255 model.
Forerunner 255: This model gets high marks for being a reliable workhorse. Marathoners and ultra-runners love the tremendous battery life and appreciate that it includes the advanced multi-band GPS at a great price point. Some users report that after using an AMOLED screen, the MIP display feels dated.
Forerunner 165: Consumers are thrilled that they finally have an affordable AMOLED option. Buyers often highlight the value for money, though advanced runners occasionally wish it included more of the deep-dive training metrics found in the 265.
Forerunner 55: Reviewers praise this as the best entry-level running watch, period. It does the basics (pace, distance, heart rate) flawlessly and is incredibly simple to use. The primary criticism is its lack of advanced health/training stats like sleep score or HRV.

Pricing & Value Comparison

The Garmin Forerunner series offers a running watch for nearly every budget. The Garmin Forerunner 55 running watch is your entry-level budget option, typically under $200, offering exceptional battery value. Moving up, the Forerunner 165 offers a huge value jump by including the desirable AMOLED screen for a mid-range price. The Garmin Forerunner 255 provides the best GPS battery endurance for its mid-range cost, while the newer Forerunner 265 swaps some of that endurance for the popular AMOLED display and Training Readiness feature. Finally, the Garmin Forerunner 965 sits in the premium tier, where you pay extra for the titanium build, full maps, and ultimate data suite.

Key Competitor Alternatives

While Garmin dominates the running market, two main alternatives are worth considering. The Apple Watch Ultra is a strong competitor for those fully immersed in the iOS ecosystem, offering superior smartwatch features but often falling short on multi-day battery life for long endurance events. For ultra-runners, Coros watches (like the Coros Pace 3 or Apex 2) offer a compelling alternative, often winning on pure battery life metrics and sometimes offering simpler interfaces for specific data points.
