The PACE 4, Forerunner 70, vívoactive 6 and Forerunner 170 crowd the top of the under $300 shelf this fall. Each is built around a different strength: maps on the PACE 4, offline Spotify on the vívoactive 6, Garmin Pay with a real altimeter on the 170, and Garmin's coaching for the least money on the 70. That makes it sound like a matter of taste. It isn't, quite. Only one of the four pairs its trick with GPS every tester trusts and a battery a marathon barely dents. Milewright's pick for a runner shopping under $300 is the COROS PACE 4, a band lower at under $250. Four separate testers came back impressed by its dual-band GPS. Free topo maps arrived in September. In a lab's run, its battery drained slowly enough to project past a full day with the screen always on. Its catch is wrist heart rate, which split the testers. If you run hard in the cold, budget for a chest strap.

What changes the answer under $300

The PACE 4 suits most runners at this money. Here's when it isn't yours.

  • You want the watch to plan your week and tell you when to rest. The Garmin Forerunner 70 brings Garmin Coach and a morning readiness score, free.
  • You want Spotify on your wrist and the phone in a drawer. The Garmin vívoactive 6 downloads playlists and pays for the coffee afterward.
  • You want Garmin's coaching and tap-to-pay in one Forerunner. The Forerunner 170 adds Garmin Pay and a barometric altimeter to the 70. Nobody has measured its battery or heart rate on this edition yet, so it waits.
  • Your budget really stops under $200. The Amazfit Active Max brings free maps and two weeks between charges. Our under $200 roundup covers that shelf, and our budget guide shows what each step up buys.

One feature is missing from every watch we weighed under $300: LTE, for taking a call without your phone. The only LTE watch we weighed sits above this ceiling, and the question on it below explains why.

COROS PACE 4: the best running watch under $300, with maps and the least charging

Our pick

Best under $300: maps, dual-band GPS and the least charging

View on Amazon (opens in a new tab)

Price band: under $250

COROS gives a separate battery figure for every GPS setting and every screen setting. That's a spec sheet worth reading. It promises 31 hours when the watch listens on both satellite frequencies, and 24 if the screen never sleeps. In that setting, screen lit throughout, DC Rainmaker logged a drain of about 4%/h. At that rate, the battery would outlast a full day on the move. A marathon barely shows on the gauge, and a first 50K leaves charge for the drive home. Between runs, testers who kept the screen on got 4 to 6 days. If your longest day runs past a marathon, our GPS battery planner shows what you'd have left at the finish.

GPS is where it earns the pick. Four testers found only minor offsets, one of them over a whole London Marathon. That's distance you can trust with a PR.

Maps arrived by firmware on September 26: topo and landscape maps worldwide, at no charge. They show where you are, but they won't route you around a closed trail. The 4 GB of storage also fills fast. COROS's own FAQ still says the PACE 4 doesn't do full mapping, a modest way to describe a feature you shipped in September. When a maker's FAQ contradicts its release notes, I read it like a drawing two revisions out of date. The newer document wins.

The catch is wrist heart rate. Three testers saw it track a chest strap closely on runs. The Quantified Scientist, testing in winter, found it poor and suspects it latched onto his stride. Owners who run in the cold or throw in fast pickups say much the same. Easy miles are fine. Intervals on a January morning want a strap.

It plays only MP3 files you copy over, and it has no payments. If those matter, see the vívoactive 6 below.

Our call: buy it if you run outdoors and want distance you can trust and maps on your wrist. Our PACE 4 review has the full story, and COROS vs Garmin sets it against its Garmin rivals pair by pair.

Garmin Forerunner 70: best under $300 for Garmin's coaching

Buy

Best for Garmin's coaching

View on Amazon (opens in a new tab)

Price band: under $250

On paper the Forerunner 70 reads like the cheap seat, with single-band GPS where the PACE 4 has two. Garmin's antennas make a fool of the spec sheet. In DC Rainmaker's testing its tracks landed on nearly the same line as a fēnix 8 Pro running multi-band, even among downtown towers. A second test team saw it keep up with multi-band watches too. Heart rate held up against chest straps on steady runs, if a beat slow to settle after a hard rep.

The reason to buy it lives on the training screens. Garmin Coach writes a plan that adjusts as your weeks go, with run/walk options for newer runners. Training Readiness tells you each morning whether today should hurt. None of it needs a subscription. It also sits on Garmin's newer software platform, which gets new features first. That matters for a watch you plan to keep three years.

Garmin claims 16 hours with all satellite systems. One tester's hour in the best GPS mode burned close to 10%/hour, a pace that projects to under two-thirds of that. It's enough for a marathon, and thin for a full day on mountain trails. Left always-on, it lasted 4.5 to 6 days for testers, around Garmin's 5.

The catch is what stays at home. There's no music and no Garmin Pay, so your playlists and your wallet stay with the phone. Routes show as a breadcrumb line, not a map. With no barometer, climbs come from GPS, and one test found them undercounted on a walk. It's a running tool and nothing more, which is exactly what plenty of runners want.

Our call: buy it if you want a watch that tells you what to run today and when to rest. Our Forerunner 70 review has the detail.

Garmin vívoactive 6: best under $300 for offline Spotify and Garmin Pay

Buy

Best for offline Spotify and Garmin Pay

View on Amazon (opens in a new tab)

Price band: under $300

The vívoactive 6 is the Garmin that admits it's also a smartwatch. Spotify and Amazon Music support it in Garmin's app store, as do Deezer and YouTube Music. A downloaded playlist plays from the watch's 8 GB while the phone stays on the kitchen counter. Garmin Pay then covers the bagel on the way home. Downloads need each service's paid tier. No Garmin plays Apple Music; type its name into Garmin's store and the results are all watch faces.

The box holds up where anyone has checked it. Garmin claims 21 hours on GPS alone, and OutdoorGearLab ran it down at 20. Garmin's manual says 8 hours with every satellite system and music running, which nobody has measured. That's a marathon with a podcast, not a trail day. Its single-band GPS came within 0.04 mi on that lab's measured course, less than a short city block.

Heart rate is good enough for easy miles. The Quantified Scientist got a correlation of 0.81 with a chest strap on runs. In plain terms, it follows the shape of a run but lags when you surge. Without Training Readiness or multi-band GPS, this is the music-and-wallet Garmin, not the training one.

The catch is the headphones. Owners keep reporting earbuds cutting out mid-run, and support hasn't fixed it for all of them. Owners of Garmin's other music watches report the same dropouts, and which headphones you pair seems to decide whether you get them. So it isn't this watch's fault alone, but it is the feature you bought it for.

Our call: buy it if phone-free Spotify is why you're shopping. If coaching matters more than playlists, the Forerunner 70 is the better Garmin. Our guide to running watches with music without a phone goes service by service.

Amazfit Active Max: best if your budget stops under $200

Buy

Best if your budget stops under $200

View on Amazon (opens in a new tab)

Price band: under $200

Amazfit claims 25 days of everyday use and 64 hours of GPS, numbers that sound measured on a nightstand. Only the everyday battery has met a tester so far. One team's watch ran 16 days with the screen always on at full brightness. Amazfit's own spec promises 10 days with the screen left on, so here the maker undersold its watch. Another went comfortably over 10 days with raise-to-wake and a few workouts a week. Nobody has run one flat on GPS, so the 64 hours is still just the box talking. Free contour maps download to the watch. Running heart rate correlated at 0.96 with a chest strap in one lab, on early firmware.

The catch is single-band GPS that changes with where you run. On open roads, one test team found distance as close as Garmin's flagships. Under trees and buildings, others watched routes drift. One walk logged 4.55 mi against a phone's 6.1. If your run is a downtown loop or a wooded trail, the PACE 4 is worth the extra band. The same holds for hikers who'd steer by those free maps under tree cover. For day hikes with maps, the PACE 4 is the watch we'd pick too.

Our call: buy it if you run open roads and the budget really stops under $200. Our Active Max review has the rest.

New this year, and what we're watching

Most of this shelf is new. Garmin's Forerunner 70 and 170 arrived in May 2026, and the Active Max in December. The PACE 4 is a year old, but it gained its maps only on September 26. Reviews written before then say it has no maps. On current firmware that's wrong, and it's the difference between this watch and a breadcrumb trail.

We're watching for battery and heart-rate results on the plain Forerunner 170, which would put it in contention. We also want a full look at the PACE 4's maps on release firmware rather than the beta. We've seen nothing announced in this band, so there's no reason to wait.

How the picks were decided

Nothing wins here on one kind of proof. Each pick needs two independent sorts of evidence about the very model you'd buy, and at least one can't come from its maker. Every battery claim sits beside what testers found, with the screen setting named, and we say what kind of finding it is. Where a tester ran the watch flat, you get that rundown. Where testers logged only a drain rate over part of the battery, we give it as a projection, not a result. Where nobody has tested the model, as with the Forerunner 170 and the Galaxy Watch Ultra (2025), we say its battery is not measured. GPS and running heart-rate results were counted tester by tester. The CPSC database shows no recall for any brand on this page.

Do I need multi-band GPS under $300?

Not if you buy a Garmin. The single-band Forerunner 70 kept pace with a multi-band flagship downtown. Other brands' single-band watches haven't shown the same, which is the Active Max's weak spot. The PACE 4 gives you dual-band anyway.

Which running watch under $300 plays Spotify without my phone?

The vívoactive 6, with Spotify Premium. The PACE 4 and Active Max play only files you copy over. The Forerunner 70 and plain 170 store no music at all. Our music without a phone guide covers every service.

Why isn't the Forerunner 170 a pick?

No tester has measured the plain 170's battery or heart rate. Its GPS tracked identically to the Forerunner 70 on the same runs. But the other results come from the Music edition. On paper, Garmin rates it 14 hours with all satellite systems, against the 70's 16. Garmin Pay and an altimeter are worth having. They aren't worth buying blind.

Is there an LTE running watch under $300?

Not among the watches we weighed. The one LTE watch we weighed, the Galaxy Watch Ultra (2025), sits above this ceiling in the under $700 band. The original 2024 Galaxy Watch Ultra shares its model code, but it's a different watch, and we haven't weighed it here. The 2025 edition brings LTE, a speaker and 64 GB, but it works only with Android phones. Its best health features want a Samsung. Samsung's own GPS battery claim is 48 hours, and only in a power-saving exercise mode. Its battery is not measured, because every test on file used the 2024 watch, and we use none of those figures.

Who it's for: Android owners who need a phone line on the run and can spend well past this page's ceiling.

Will any of these make me pay a subscription?

None you need. COROS and Amazfit have no paid tier. Garmin's Connect+ is optional, and the coaching stays free. Music downloads need the streaming service's paid plan.

Our pick under $300: the COROS PACE 4

Our pick

Best under $300: maps, dual-band GPS and the least charging

The Forerunner 70 coaches better, and the vívoactive 6 plays Spotify. Neither, nor the cheaper Active Max, matches the PACE 4 where trust is decided. That's distance you'd put on a race report, and a battery that outlasts the race. The maps come free on top. If you can stretch further, our roundup of running watches one budget up shows what more money buys. For a runner spending under $300, buy the PACE 4.

COROS PACE 4, tester by tester

  • Variant: standard polymer-bezel edition, model W336, FCC ID 2BBGF-W336. The aluminum and Black Crystal editions share the internals but are separate listings. A second FCC filing named PACE 4 (W335) exists with no stated difference and no US listing seen.
  • GPS: DC Rainmaker's side-by-side tracks on road, trail and city; Tom's Guide against a Forerunner 970 and Suunto Vertical 2; The Run Testers over six months including the Paris Half and London Marathon against a Forerunner 970; The Quantified Scientist on repeated loops. TechRadar's distance check against a single Huawei watch is a weak method and carried no weight.
  • Heart rate: DC Rainmaker spot-on on runs, weaker on outdoor rides with quick stop/starts. Tom's Guide close to a chest strap with spikes at the start and after pauses. The Run Testers matched a Forerunner 970 in races. The Quantified Scientist (Polar H10 reference, winter) found running poor with suspected cadence lock, indoor cycling r = 0.97. Owners lean his way in the cold; two tattooed owners report it working where a Forerunner 570 didn't. Open, likely temperature, fit and wrist.
  • Maps: public beta Sept 4, 2026, released in V3.2008.0 on Sept 26. Non-routable. On DC Rainmaker's watch, more than half of the 4 GB was already taken before any maps went on. He tested the beta and saw slow rotation; no review since covers release firmware. Tom's Guide (Nov 2025), TechRadar (Feb 2026) and The Run Testers (May 2026) predate the maps. The coros.com FAQ is stale.
  • Battery between runs with raise-to-wake: 10 to 14 days with a few runs and rides a week (TechRadar).
  • Music: MP3 only, per COROS Help; no streaming services.
  • One US owner who runs only indoors reports VO2 max and Running Fitness staying blank for months; unresolved.
  • Brand: the May 2026 firmware bricking hit mostly two to four year old models, the PACE 3 most; COROS replaced watches that died after the update. 2-year warranty.

Call on this evidence: buy it, the overall pick.

Garmin Forerunner 70, tester by tester

  • Variant: 43mm, six US color SKUs (010-04307-00 to -05), same hardware.
  • DC Rainmaker (May 2026, media loaner and his own retail unit): GPS virtually identical to a fēnix 8 Pro in multi-band mode on trails, gravel and a downtown test; HR generally very good against an HRM-Fit strap, one missed climb on a gravel ride.
  • The Run Testers (June 2026, two runners): matched multi-band watches; 4.5 days always-on with a run every day.
  • TechRadar (three weeks): HR held up against Garmin and MyZone straps on steady and hot runs; battery drain close to 10%/hour in one hour of best-mode GPS, brightness not stated. One sample; open.
  • Tom's Guide (two weeks, newer runner): 6 days always-on, less GPS time than The Run Testers; climb undercounted on a walk against an Apple Watch SE 3. DC Rainmaker saw only a small difference on a hilly trail run. Explained by method and the missing barometer.
  • DC Rainmaker says in his comments that the battery is user-replaceable; no procedure or US parts source yet.
  • One owner on YouTube reported two Bluetooth pairing failures in about four weeks.

Call on this evidence: buy it, for runners who want Garmin's coaching.

Garmin vívoactive 6, tester by tester

  • Variant: one 42mm size, M/N A04951, FCC ID IPH-04951.
  • OutdoorGearLab: 20 h GPS-only rundown against 21 h claimed; 5 days always-on; 118 min to charge from empty; within 0.04 mi on its measured course, a touch behind the multi-band watches it tested alongside; HR 1.0 bpm median off a Polar Verity Sense armband on steady runs after warm-up.
  • The Quantified Scientist (Polar H10): running r = 0.81 with delays on increases and few runs; indoor cycling 0.89; outdoor cycling 0.82; weightlifting 0.62.
  • Tom's Guide (one month): no barometer, climb undercounted against an Apple Watch SE and Galaxy Watch 7.
  • Music: Spotify, Amazon Music, Deezer and YouTube Music each list it on their Connect IQ pages; Apple Music has no Garmin app. No independent battery figure with music.
  • Owners: the most-viewed complaints on Garmin's forum concern auto-brightness that can't be turned off and the screen waking at night (firmware 18.29 and 18.32), with no posted fix. Three Reddit owners report headphone dropouts; the same pattern appears on Garmin's other music watches.
  • Platform: the lineup sources we read name the Forerunner 70 and 170, not the vívoactive 6, on Garmin's newer shared platform. It also has no barometer.
  • DC Rainmaker's coverage of the vívoactive 6 is a first-look article at launch; he has not published an in-depth review of it.

Call on this evidence: buy it, for runners who want phone-free Spotify and Garmin Pay.

Amazfit Active Max, tester by tester

  • Battery claims (Amazfit US): 25 days typical use; 64 h continuous GPS. Amazfit's always-on figure of 10 days comes from its spec as restated in the Gadgets & Wearables review. Nobody on file has run the watch down on GPS, so the 64 h claim is untested.
  • The Run Testers (three runners, Apr 2026): 16 days always-on at full brightness, with only a sliver of charge lost overnight; distance close to a fēnix 8 Pro and Forerunner 970 on open routes; live pace lagged; HR spiked in intervals; no auto screen lock, so a sleeve brush ended runs.
  • The Quantified Scientist (pre-release firmware, Polar H10): running r = 0.96, indoor cycling 0.98; not good enough for outdoor cycling or lifting.
  • Tom's Guide (several months): one walk 4.55 mi against 6.1 mi on a phone; a ski day matched an Instinct 3; it also found map navigation needlessly complicated. T3: routes drift off roads; over 10 days raise-to-wake.
  • Amazfit's manual wasn't available to our research, so this page gives no settings advice for it. US bank support for Zepp Pay is unconfirmed.

Call on this evidence: buy it, for open-road runners whose budget stops under $200; not for hikers navigating under tree cover, where the PACE 4 is our pick.

Forerunner 170 (non-Music)

  • Variant 010-03920-00/-01. GPS from DC Rainmaker and The Run Testers. Battery and HR tests by Tom's Guide and TechRadar used the Music edition and don't count here.
  • Tom's Guide's claim that both the 70 and 170 have NFC payments is wrong; Garmin Pay is 170 only.

Call on this evidence: considered, not a pick, until its own battery and heart rate are measured.

Galaxy Watch Ultra (2025), 47mm LTE, above this ceiling

  • SM-L705U, in the under $700 band. Per SamMobile, the only changes from the 2024 watch are 64 GB storage and a Titanium Blue color, so a unit can't be dated by model code.
  • The original 2024 Galaxy Watch Ultra shares the SM-L705U family code but is a separate product, not weighed on this page; nothing here speaks to it.
  • Every lab test on file is of the 2024 watch. This edition's battery, GPS and heart rate are not measured, and no 2024 figure is used on this page.
  • One 2025 owner on a Pixel got no VO2 max after a phone-free run; one says offline Spotify with headphones works well.
  • Superseded by the Ultra 2 in July 2026, per Android Central. Samsung promised four major OS updates for the 2025 version.

Who it's for: Android owners who need LTE on the run and can spend in the under $700 band, not buyers shopping under $300.

Skip these, and also considered

WatchWhy it lost here
Forerunner 170 (non-Music)The Garmin with coaching, Garmin Pay and an altimeter, held back only because its own battery and heart rate are unmeasured. The first watch we'd re-check.
Suunto RunAccurate dual-band GPS at under $200, but DC Rainmaker found wrist HR lackluster on track intervals, owners find plans from Runna and Suunto's own AI never reach the watch, and the Run 2 has replaced it. Our under $200 roundup buys it for self-coached runners downtown or under trees; at under $300 the PACE 4 does that job with maps.
Forerunner 165An older Garmin without Training Readiness; the Forerunner 70 is the better start.
COROS PACE 3No maps, 15 h of dual-frequency GPS claimed, lab tests only from 2023, and the model the May 2026 bricking hit most often. The PACE 4 replaces it.
Galaxy Watch Ultra (2025)Above this ceiling in the under $700 band, Android only, unmeasured on this edition, and already succeeded by the Ultra 2.
