Garmin Forerunner 165 vs Fitbit Charge 6: Which Fits Your Routine?

Forerunner 165 is the documented fit if you want a daily suggested workout presented from the watch’s Run activity; it requires an estimated VO₂ max and updates with training habits, recovery, and VO₂ max. Charge 6 also has documented training feedback: Cardio Load with a daily target, an in-app intensity map after outdoor GPS exercise, and Google Health Premium tools including Daily Readiness and recommended workouts. These are different workflows, not proven equivalents or a test of coaching results.

The buying question

Do you want a daily suggested workout surfaced in the Forerunner’s Run activity, or Charge 6’s cardio-load/readiness feedback and app-based workout tools, with some features listed under Google Health Premium?

Garmin documents an on-watch Run daily suggestion that requires an estimated VO₂ max and updates with training habits, recovery time, and VO₂ max. Google documents Charge 6 Cardio Load targets, post-GPS workout-intensity feedback, and Premium readiness/coaching tools. The pages describe different workflows and do not establish equivalence or comparative training results.

Quick verdict

Choose Garmin Forerunner 165 Running Smartwatch if

  • You want Garmin’s on-watch Run suggestion and understand its VO₂ max estimate prerequisite.
  • You prefer a watch interface with touchscreen navigation plus five named physical controls.

Choose Fitbit Charge 6 Fitness Tracker, Obsidian/Black if

  • You prefer the Charge 6 tracker format and its stated 36.73 × 23.09 × 11.20 mm dimensions.
  • You want its documented Cardio Load target and post-GPS in-app intensity map; check Premium terms if Daily Readiness or coaching is important.

When to skip: Skip this pair if you need a non-wrist-worn wearable; both options are wrist-worn devices, in different watch and tracker forms.
When the recommendation changes
  • If you need a particular prescribed run-session workflow, verify that the currently documented features match the workouts you want; this comparison does not equate a cardio-load target or coaching prompt with Garmin’s on-watch Run suggestion.
  • If your deciding factor is GPS or heart-rate accuracy, seek an applicable controlled test for both exact models; feature documentation does not establish accuracy superiority.

The differences that matter

Running Training Workflow

Garmin Forerunner 165 Running Smartwatch

In the Run activity, a daily suggested workout appears; an estimated VO₂ max is required first, and suggestions update with training habits, recovery time, and VO₂ max.[2]

Fitbit Charge 6 Fitness Tracker, Obsidian/Black

Google documents 40+ exercise modes and built-in GPS for pace and distance without a phone. It also documents a Cardio Load daily target based on cardio load and readiness, plus an in-app Workout Intensity Map after outdoor GPS exercise showing pace and heart-rate zones. Google lists Daily Readiness Score as available with Google Health Premium and describes recommended workouts based on that score within Premium. These are readiness/load feedback and app-based workout guidance; the public page does not establish that they are equivalent to Garmin's Run daily-suggested-workout flow.[4]

What this changes: The documented paths differ in what they present: Garmin surfaces a daily suggested workout inside Run after a VO₂ max estimate, while Google documents Charge 6 cardio-load/readiness feedback, a post-GPS intensity map, and Premium coaching/recommended workouts. They are not established as equivalent plans or compared for effectiveness.[2, 4]

The better fit depends on your priorities

Display And Controls Form Factor

Garmin Forerunner 165 Running Smartwatch

The Forerunner 165 manual describes a touchscreen and five physical controls: LIGHT, UP, DOWN, START/STOP, and BACK. The assigned manufacturer product page identifies the exact 010-02863-20 Black/Slate Gray Forerunner 165.[3, 1]

Fitbit Charge 6 Fitness Tracker, Obsidian/Black

Google identifies Charge 6 as a tracker, lists dimensions of 36.73 × 23.09 × 11.20 mm and weight of 30 g, and documents a color touchscreen with an easy side navigation button.[5, 4]

What this changes: Buyers who prefer physical multi-button navigation on a running watch can favor the Forerunner’s documented interaction model; buyers who prefer a tracker form and the Charge 6’s stated size can favor its format. These facts do not prove comfort, visibility, or ease-of-use superiority.[3, 1, 5, 4]

The better fit depends on your priorities

Best for your routine

A runner who wants a daily suggested workout surfaced from the Forerunner 165 Run activity and can meet its VO₂ max estimate prerequisite.

Best fit: Garmin Forerunner 165 Running Smartwatch

Based on listed features, not comparative testing.

The Forerunner manual documents this on-watch workflow and its update inputs. Charge 6 documents Cardio Load/readiness feedback and Premium app-based guidance, which are not established here as the same kind of run workout. This is feature fit, not a training-results winner.

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

No live offer or price-history claim is used. If one costs more at checkout, decide whether its specific training workflow or device format is worth that current difference; this draft does not estimate a premium threshold.

Price evidence is unavailable for a timing recommendation. Check offers at purchase; this draft gives no purchase-timing recommendation.

Limitations

  • No Pickoryx hands-on test was conducted.
  • Garmin documents a daily suggested workout inside Run after an estimated VO₂ max is available. Google documents Charge 6 Cardio Load with a daily target, an in-app Workout Intensity Map after outdoor GPS exercise, and Google Health Premium readiness/coaching features. These pages do not establish that the workflows are equivalent or compare their training effectiveness.
  • Google currently lists Daily Readiness Score as available with Google Health Premium and describes recommended workouts based on that score in Premium; feature access and terms should be checked for the buyer’s account.
  • Official feature descriptions do not compare GPS, step-count, heart-rate, sleep, or other real-world accuracy. The Tom’s Guide walk-count exercise found during discovery is an individual publisher test and is not used to generalize accuracy here.
  • No comfort or fit conclusion is drawn from dimensions or weights. Try the device and band on your own wrist if fit is decisive.
  • No medical advice, diagnosis, or treatment conclusion is offered.
  • No live price, offer, shipping, stock, or membership-plan statement is included.

Questions shoppers ask

Does the Forerunner 165 suggest a daily running workout?

Garmin’s manual says a daily suggestion appears after you open Run; the watch needs an estimated VO₂ max first, and the suggestion updates with training habits, recovery time, and VO₂ max.

Does Charge 6 provide training feedback too?

Google documents Cardio Load with a daily target based on cardio load and readiness, plus an in-app Workout Intensity Map after outdoor GPS exercise. Google lists Daily Readiness Score as available with Google Health Premium and describes recommended workouts based on that score in Premium. These features are not shown to be equivalent to Garmin’s specific on-watch Run suggestion. Check current app feature terms; this article does not compare coaching effectiveness.

Can Charge 6 record pace and distance without a phone?

Google’s Charge 6 product page says its built-in GPS can show pace and distance on the wrist without a phone. This answers a feature question, not how its accuracy compares with Garmin.
