Garmin Forerunner 55 GPS Running Watch review

Have you ever bought something because you imagined the quiet shape it would take in your life — the way a watch might sit on your wrist while you run, while you cook, while you breathe — and then wanted to know if it would actually do what you pictured?

First impressions of the Garmin Forerunner 55, GPS Running Watch with Daily Suggested Workouts, Up to 2 weeks of Battery Life, Aqua One Size (Renewed)

You notice the watch before you notice anything else: its smallness, its promise. The Garmin Forerunner 55 arrives as a tidy, familiar object — circular face, clear digits — and you begin to think about routines. When you open the box (or the renewed packaging), you’ll feel reassured by the simplicity. It’s not extravagant; it’s purposeful.

You expect a running partner that won’t demand much, and at first glance this watch seems to offer that. The fact that it’s renewed tells you that someone else used it before, and that history makes the object feel less like a newfangled device and more like a trusted tool.

What the watch aims to do

Garmin has built this model to support runners who want focused, reliable metrics without wrestling with complexity. It tracks heart rate at the wrist, uses GPS to map your runs, suggests workouts tailored to your training history, and promises long battery life so you barely have to think about charging.

You won’t find every advanced multisport feature here, but you will find earnest coaching, daily suggestions, and smart battery management — features that nudge you toward consistency.

Design and comfort

The Forerunner 55 has a pared-back aesthetic that’s almost deliberately modest. You’ll wear it without feeling like you’re wearing a gadgeted trophy, and that’s exactly its strength.

The band is pliable and the case sits close to your wrist; it’s easy to forget you’re wearing it when you move through a day. Because it’s one size and marketed as “Aqua,” the implication is that it will handle water without fuss, so you can switch from run to pool to shower without extra thought.

Materials and feel

The materials feel utilitarian rather than luxurious: matte plastic case, silicone strap, durable buttons. You’ll notice practical touches, such as easily pressed buttons for navigation and an unobtrusive bezel that keeps the display protected.

You’ll also probably appreciate how the watch avoids being flashy. If you want something to blend into your daily movement, this design accomplishes that quietly and well.

Display and readability

The Forerunner 55 uses a crisp display with a resolution of 480 x 272, and that matters more than you might expect when you’re mid-run and your hands are cold. The digits are legible, and the contrast holds up outside in daylight.

You won’t get a vibrant AMOLED screen here, but you’ll get an always-on, power-efficient display that prioritizes clarity. For tracking pace, distance, and heart rate at a glance, it does exactly what you need.

Interface and navigation

Garmin keeps the interface simple. Buttons guide you through widgets and activities, and the menu structure is straightforward enough that you won’t be constantly consulting a manual. If you prefer tapping screens, this model leans more on physical controls — which is often a plus when you’re sweaty or wearing gloves.

You’ll find the menu predictable, and that predictability becomes comforting over time.

Battery life and charging

Battery life is one of the Forerunner 55’s strongest promises: up to 2 weeks in smartwatch mode and up to 20 hours in GPS mode. That’s the kind of endurance that changes how you plan.

You stop scheduling charging sessions around workouts, and you can go on weekend trips with less anxiety about battery management. For everyday use, the watch quietly hums along for days.

Practical expectations

Two weeks in smartwatch mode means you can track daily activity, sleep, and heart rate without constant tethering to a charger. If you crank up GPS to marathon training levels, that 20-hour ceiling still gets you through a long event.

You should expect battery life to vary with settings — backlight intensity, notifications, and frequency of GPS-enabled sessions will alter real-world numbers. But the baseline is generous.

GPS accuracy and tracking

GPS is one of those quiet hero features. The Forerunner 55 uses built-in GPS to measure where you run and how fast you go, and in most conditions it gives you reliable results. You’ll look at a route map and recognize the roads and turns you took, even if foliage or tall buildings occasionally confuse the signal.

If you’re the kind of runner who checks splits obsessively, you’ll be pleased by its consistency. The pace readings are steady, which helps you trust the guided workouts and race predictions.

When GPS struggles

There are moments when GPS is imperfect: dense tree cover, urban canyons, and inside track runs can introduce small errors. You’ll notice minor route smoothing or jumps in the map if you scrutinize every meter, but for everyday running and training purposes, the Forerunner 55 is precise enough.

If you want pro-level geo-precision for trail mapping or GPS-based art runs, you might look elsewhere — but for regular road, treadmill, and park running, it’s dependable.

Heart rate tracking and sensors

Wrist-based heart rate sensing has become standard, and the Forerunner 55 does a competent job measuring your pulse throughout the day and during workouts. Remember: this is not a medical device, but it provides useful data for training and recovery.

During steady-state runs and intervals, the heart rate curves make sense; you’ll see increases during hills and recoveries after sprints. For the bulk of your training decisions, the heart rate readings are actionable.

Advanced wellness features

The watch pairs heart rate with other metrics like intensity minutes, fitness age, and all-day respiration to give you a sense of your overall state. These features are designed to create a broader picture of how you’re responding to training, not just raw numbers.

If you like connecting dots — sleep quality, stress markers, and training load — you’ll find these wellness features helpful when you’re pacing how hard to push on any given day.

Training tools and suggested workouts

One of the most compelling components here is the Daily Suggested Workouts feature. The watch offers workouts of varying intensities based on your training history, fitness level, and recovery times, so you don’t have to invent structure midweek.

You’ll get suggestions tailored to where you’ve been and where you might sensibly go next, which is a gentle, effective nudge toward consistency.

Race time predictions and finish estimates

The Forerunner 55 includes race time predictions and finish estimates, which can be both motivating and informative. When you’re planning a race day strategy, these estimates help you test pacing scenarios in training so you aren’t improvising on race morning.

You won’t get a guarantee, of course, but you will get data-driven projections that make your goals feel more attainable.

PacePro feature

PacePro offers GPS-based pace guidance for a selected course or distance to help you plan a race or a run with specific pacing demands. It’s especially useful when you want a pacing strategy that accounts for elevation or a specific split plan.

You should note it’s not compatible with on-device courses, so you’ll prepare your plan through Garmin Connect and let the watch guide you during the run.

Using PacePro well

When you set realistic pace targets and follow its cues, you’ll find it prevents the common error of starting too fast or losing composure on a tricky climb. The feature adds a tactical layer to training that’s accessible even if you don’t consider yourself detail-oriented.

You’ll feel like you have a calm, methodical guide rather than an overbearing coach.

Activity profiles and multisport support

The Forerunner 55 supports a surprising number of built-in activity profiles: running, cycling, track run, virtual run, pool swim, Pilates, HIIT, breathwork, and more. You’ll be able to switch quickly between activities without micromanaging settings.

For most people who spend time in a few different training modes, this versatility means the watch works as a daily companion for varied workouts.

Swimming and “Aqua” designation

Because the product listing includes “Aqua,” you can assume the watch is suitable for pool swims — and the watch indeed supports pool swim tracking. You’ll get basic swim metrics and the comfort of wearing the watch in the water.

If you’re a triathlete seeking advanced open-water swim metrics, you may want a model with more detailed stroke analytics, but for lap swims and general aquatic sessions the Forerunner 55 fulfills its promise.

Smartwatch features and Garmin Connect

The Forerunner 55 connects to the Garmin Connect app and the Connect IQ Store, letting you customize watch faces, fields, apps, and widgets. That small personalization helps the device feel like yours rather than just functional.

You’ll also get notifications from your phone — messages, calls, app alerts — which can be handy but also a reminder to set boundaries if you want uninterrupted runs.

What customization offers you

The Connect IQ Store is a boon if you like tailoring your data screens to specific training metrics. You can download free watch faces and specialized fields that show the stats that matter most to you.

If you’re someone who likes to tinker, these options let you make the watch reflect your priorities without changing the core simplicity of the device.

Wearability, strap changes, and sizing

Because the watch is “One Size,” most wrists will accept it without drama. The strap is adjustable and easy to swap if you want aftermarket options. It’s light enough to not interfere with cadence or comfort during longer runs.

You’ll find that the watch sits low enough to not catch on clothing and high enough to ensure the optical sensor remains engaged with your skin.

Considerations for small wrists

If you have very small wrists, you might notice the case feels slightly large at first. Over time, though, the lightness reduces this sensation. The comfortable silicone strap allows for fine adjustment, and that helps with consistent heart rate readings.

Renewed condition: what to expect

Buying the Garmin Forerunner 55 renewed means you’re likely getting a unit inspected and restored to full working order. You should expect functional performance comparable to new, though watch cosmetic condition may vary depending on the refurbisher.

You’ll also want to check the seller’s warranty and return policy. Many renewed items come with a limited guarantee, and confirmed coverage will give you peace of mind.

Inspecting a renewed unit

When your watch arrives, look for signs of usage like hairline scratches or wear on the band. Test the battery, ensure GPS locks, and connect to Garmin Connect to verify firmware updates. If anything feels off, use the seller’s return window.

You’ll prefer a renewed buy when it balances cost savings against the assurance of a solid return policy.

Pricing value and who should consider it

If you’re seeking a sensible, affordable running watch with thoughtful training tools and excellent battery life, the Forerunner 55 offers substantial value. The renewed option often brings down price further, making it approachable for runners who want quality without the highest-end cost.

You’ll get most of the features an everyday runner needs without paying for features you never use. For many people, that’s precisely the point.

Comparison to higher-end models

When you compare the Forerunner 55 to more expensive Garmin models, the differences usually involve advanced metrics, more detailed navigation features, and richer multisport capabilities. If you’re training for elite performance or need triathlon-first tools, other models may provide greater depth.

You’ll still find the Forerunner 55 meets the needs of beginner to intermediate runners and many avid runners who prefer simplicity.

Pros and cons

Every device has trade-offs, and the Forerunner 55 is no exception. Understanding these helps you decide if it fits your habits.

You’ll appreciate the long battery life, reliable GPS, and thoughtful training suggestions. On the other hand, you won’t find advanced mapping, multi-band GPS, or exhaustive physiological sensors.

Quick look at strengths and limitations

• Strengths: long battery life, simple interface, clear display, Daily Suggested Workouts, race predictions.
• Limitations: not packed with pro-level metrics, less premium materials, limited advanced navigation.

You’ll find that the strengths align well with steady training goals, and the limitations mainly affect athletes pursuing high-performance analytics.

Practical tips for getting the most out of the watch

There are small habits that make the watch feel indispensable. Charge it to full before a big run, wear it a bit snugger during high-intensity sessions for better heart rate accuracy, and let it sync nightly so the suggested workouts stay relevant.

You’ll also want to create a simple watch face layout that shows your core metrics — pace, distance, heart rate — so you don’t lose time toggling screens mid-run.

Routine setup tips

• Update firmware through Garmin Connect as soon as you connect the watch.
• Calibrate heart rate by doing a few controlled efforts and comparing to perceived exertion.
• Use the suggested workouts for variety but adjust intensity when life and sleep say you need a lighter day.

You’ll quickly realize the watch responds to consistent, small inputs more than dramatic adjustments.

Everyday usage scenarios

Whether you’re prepping for a 5K, building a running habit, or keeping tabs on daily activity, the Forerunner 55 fits into ordinary life with a quiet, steady competence. You’ll slip the watch on and find it integrates into your routine rather than reshaping it.

Its battery life and simple interface are particularly useful for commuters and busy people who don’t want their tech to demand constant babysitting.

Travel and long runs

If you travel for races or training camps, the battery life and GPS reliability reduce stress. You won’t be constantly searching for adaptors or worrying about losing data mid-run.

You’ll appreciate how it frees mental space to think about pacing and scenery rather than logistics.

Setup and pairing with Garmin Connect

Pairing is straightforward. You download Garmin Connect to your phone, open the app, and follow the prompts to add your device. Once paired, the watch syncs activities, firmware updates, and suggested workout data.

You’ll appreciate how the app presents training history in readable timelines and how it helps you schedule and analyze workouts without overwhelming you.

Syncing and firmware

Keep the firmware updated — Garmin occasionally adds features or improves stability. Sync daily or nightly to ensure your suggested workouts reflect your most recent activity.

You’ll find that consistent syncing makes the watch smarter and more responsive to where your training is actually going.

Who should buy the Forerunner 55?

This watch is ideal if you want a reliable, no-nonsense running watch with coaching features and excellent battery life. You’ll love it if you’re a beginner building a training habit, an intermediate runner wanting guided workouts, or someone who prefers simplicity over a barrage of metrics.

If you’re a competitive athlete chasing every fractional performance edge, you might look at higher-tier models, but for the majority of runners, this is a focused, practical choice.

Who might pass on it

If you’re heavily into multisport competition, trail ultra-running with advanced mapping needs, or you want a premium finish and touchscreen luxuries, you’ll likely want a different model. You’ll also skip it if you insist on chest-strap heart rate for every session.

Comparisons to similar Garmin models

Compared to entry-level Garmin models, the Forerunner 55 offers a stronger focus on running features and better suggested workouts. Against mid-range watches, it sacrifices some higher-end sensors but retains core training tools.

You’ll find it hits a sweet spot between affordability and the features that actually change running outcomes.

Comparison examples

• Versus basic fitness trackers: More focused on running metrics and better for structured training.
• Versus premium Garmin runners: Fewer pro-level metrics and navigation features, but often enough for non-elite athletes.

You’ll make your decision based on whether you want breadth of multisport features or depth in user-friendly running guidance.

Longevity and firmware support

Garmin typically supports its devices with firmware updates and app improvements for years after release. You’ll likely see incremental improvements in usability and features if you keep the device updated.

The renewed nature does not change Garmin’s support; you’ll still get firmware updates as long as Garmin continues supporting the Forerunner 55.

Caring for the watch

Treat it like a tool: keep the charging contacts clean, avoid prolonged exposure to harsh chemicals, and replace the band if it shows wear. You’ll get the most from it if you maintain these small habits.

Frequently asked questions

You’ll have practical questions, and many of them are straightforward.

• Is the heart rate accurate? It’s reliable for training and daily metrics but not a medical-grade measurement.
• Can I use it for swimming? Yes — it supports pool swim tracking and is suitable for typical aquatic use.
• Does it support music? This model does not store music onboard; you’ll rely on your phone for music playback.
• Is it compatible with Strava and other apps? Yes — Garmin Connect syncs with many third-party services so your runs can live where you prefer.

You’ll find most common queries answered in the watch’s documentation or through Garmin Connect’s help resources.

Final verdict

The Garmin Forerunner 55, GPS Running Watch with Daily Suggested Workouts, Up to 2 weeks of Battery Life, Aqua One Size (Renewed) is a thoughtful companion for runners who want clarity, endurance, and gentle guidance. It doesn’t try to be every possible gadget; instead, it focuses on reliable tracking, battery resilience, and training features that actually help you run better.

You’ll buy it because you want a watch that assists without demanding attention. It’s the kind of device that fits into the background of your life and becomes part of the rhythm of your weeks — the steady, reassuring presence that nudges you toward consistency and helps you measure progress in small, meaningful increments.

Summary: should you get it?

If you want minimal fuss, solid GPS, daily suggested workouts that adapt, and a watch that lasts multiple days between charges, then yes — this watch is a sensible, effective pick. You’ll save money with a renewed unit and still get the core experience that Garmin designed for everyday runners.

If you want exhaustive analytics, advanced navigation, or luxury materials, look at other models. Otherwise, put this watch on your wrist, sync it, and let it quietly do what it was built to do: help you run a little wiser and a little more often.
