There is no single running smartwatch that suits every runner. This shortlist has four supported options—not five—because the available evidence identifies four candidates rather than a fully substantiated fifth. Choose by training depth, GPS battery life, phone ecosystem and how much you want the watch to do off the run.
How to choose a running smartwatch
Start with what you need during training. If pace, distance, heart rate and route tracking are enough, a simpler watch may do the job. Structured workouts, training-load measures and recovery insights matter more if you use them to guide a plan. Also consider whether the watch will be an everyday smartwatch or mainly a running tool.

- Battery: Check GPS runtime for the activity you plan to do. Watch-mode estimates and GPS estimates describe different use cases; music, maps, screen settings and satellite choices can affect runtime.
- Phone fit: If you want calls, apps and broad smartwatch functions, confirm compatibility with your phone before buying. Apple Watch Ultra 3 is a candidate for iPhone users who want that wider role.
- Display and controls: AMOLED screens are vivid, while lower-power display types can help extend runtime. Physical buttons can be easier to use in rain, with gloves or when your hands are sweaty.
- Heart rate: Wrist optical sensing is convenient. For precise zones or intervals, consider a chest strap and verify that it works with the specific watch.
- Price and availability: Both change over time and by region. Check current local listings and model details before purchase.
Four running watches to consider
The recommendations below are organized by the kind of runner or use case they suit. TechRadar names the Garmin Forerunner 70 as its overall pick, but that does not make it the right choice for every runner. Its guide also names the COROS PACE 3 as a budget option, the Garmin Forerunner 965 for deeper training data, and Apple Watch Ultra 3 for iPhone users. TechRadar’s running-watch guide is the source for these recommendations and the battery and weight figures below.
Garmin Forerunner 70: a general-purpose starting point
TechRadar selects the Forerunner 70 as its overall pick. It also names it as an option for beginners who need core running measures such as pace, distance and heart rate, rather than a feature set built around advanced training analysis.
#1 Best Overall
- Easy-to-use running smartwatch with built-in GPS for pace/distance and wrist-based heart rate; brilliant AMOLED touchscreen display with traditional button controls; lightweight design in 43 mm size
- Up to 11 days of battery life in smartwatch mode and up to 19 hours in GPS mode
- Reach your goals with personalized daily suggested workouts that adapt based on performance and recovery; use Garmin Coach and race adaptive training plans to get workout suggestions for specific events
- 25+ built-in activity profiles include running, cycling, HIIT, strength and more
- As soon as you wake up, get your morning report with an overview of your sleep, recovery and training outlook alongside weather and HRV status (data presented is intended to be a close estimation of metrics tracked)
COROS PACE 3: a lighter, budget-oriented option
TechRadar positions the PACE 3 as a budget choice and a candidate for beginner runners. It lists the watch at 32 g, with estimated battery life of up to 24 days in watch mode and 38 hours using GPS. Those are source-listed estimates, not a promise of runtime in every configuration.
COROS describes the PACE 3 as a lightweight GPS sport watch for runners and multisport athletes. Check the official COROS PACE 3 page for current product details.
Rank #2
- Easy-to-use running watch monitors heart rate (this is not a medical device) at the wrist and uses GPS to track how far, how fast and where you’ve run.Special Feature:Bluetooth.
- Battery life: up to 2 weeks in smartwatch mode; up to 20 hours in GPS mode
- Plan your race day strategy with the PacePro feature (not compatible with on-device courses), which offers GPS-based pace guidance for a selected course or distance
- Run your best with helpful training tools, including race time predictions and finish time estimates
- Track all the ways you move with built-in activity profiles for running, cycling, track run, virtual run, pool swim, Pilates, HIIT, breathwork and more
Garmin Forerunner 965: for runners who want more training data
TechRadar recommends the Forerunner 965 for runners seeking deeper training data. The guide lists its weight as 52 g and its battery estimates as up to 23 days in watch mode, 31 hours using GPS only, or 10 hours using GPS plus music. The GPS figures describe different configurations; music use is not directly comparable with GPS-only runtime.

Rank #3
- Designed with a bright, colorful AMOLED display, get a more complete picture of your health, thanks to battery life of up to 11 days in smartwatch mode (5 days display always-on)
- Body Battery energy monitoring helps you understand when you’re charged up or need to rest, with even more personalized insights based on sleep, naps, stress levels, workouts and more (data presented is intended to be a close estimation of metrics tracked)
- Get a sleep score and personalized sleep coaching for how much sleep you need — and get tips on how to improve plus key metrics such as HRV status to better understand your health (data presented is intended to be a close estimation of metrics tracked)
- Find new ways to keep your body moving with more than 30 built-in indoor and GPS sports apps, including walking, running, cycling, HIIT, swimming, golf and more
- Wheelchair mode tracks pushes — rather than steps — and includes push and handcycle activities with preloaded workouts for strength, cardio, HIIT, Pilates and yoga, challenges specific to wheelchair users and more (data presented is intended to be a close estimation of metrics tracked)
Apple Watch Ultra 3: for iPhone owners who want broader smartwatch use
TechRadar identifies Apple Watch Ultra 3 as a candidate for iPhone users who want calls, apps and more general smartwatch functions alongside running features. Its stated tradeoff is more frequent charging than dedicated running watches. Consult Apple’s watch comparison page for current model details, and confirm compatibility with your iPhone and the features you plan to use.
Which running watch makes sense for your situation?
- You are new to running: Start with the Forerunner 70 or PACE 3 if pace, distance, heart rate and routes cover your needs. Avoid paying for training metrics you do not expect to use.
- You follow a structured plan: Consider the Forerunner 965 if you want deeper training data. Decide which metrics and workout features you will actually use before prioritizing them.
- You run ultramarathons or trails: Prioritize GPS runtime for your expected outing and route guidance. Compare like-for-like operating modes, including whether you will use music, maps or different satellite settings.
- You want one watch for running and daily life: If you use an iPhone and value calls, apps and broader smartwatch features, consider Apple Watch Ultra 3 and weigh those benefits against more frequent charging.
How to interpret battery figures
Battery estimates are useful for narrowing a shortlist, but they are not interchangeable. Watch mode describes a different pattern of use from GPS tracking, and GPS-only runtime differs from GPS with music. Screen behavior, maps, satellite settings and other features can change actual runtime. Match the figure to the way you plan to use the watch, especially for long runs and races.
Rank #4
- Brilliant AMOLED touchscreen display with traditional button controls; lightweight design in 46 mm size
- Up to 13 days of battery life in smartwatch mode and up to 20 hours in GPS mode
- As soon as you wake up, get your morning report with an overview of your sleep, recovery and training outlook alongside HRV status, training readiness and weather (data presented is intended to be a close estimation of metrics tracked)
- Plan race strategy with personalized daily suggested workouts based on the race and course that you input into the Garmin Connect app and then view the race widget on your watch; daily suggested workouts adapt after every run to match performance and recovery
- Training readiness score is based on sleep quality, recovery, training load and HRV status to determine if you’re primed to go hard and get the most out of your workout (data presented is intended to be a close estimation of metrics tracked)
The weights and battery estimates attributed to TechRadar above are product specifications reported in its guide. TechRadar describes its own testing process as wearing watches for at least two weeks, comparing heart-rate data with monitors and a control watch, and recording battery use under typical use. Those statements describe TechRadar’s process, not independent testing for this article.

Why this is a four-watch shortlist, not a top five
The available comparison supports four named candidates. It does not establish a fifth model with enough current product information and independent comparison evidence to justify a recommendation. Adding another watch merely to fill out a ranking would imply a level of evaluation that is not established here. The recommendations are therefore conditional, not a claim that these are the only suitable running watches.
