COROS APEX 4Best under $500
Most budget running watches are cheap the way a rental car is cheap: everything works except the thing you actually wanted. The COROS PACE 4 is the exception. Milewright's pick for a runner on a hard budget is the PACE 4. It brings the two things budget watches usually leave on the shelf. One is multi-band GPS that every tester found as clean as Garmin's flagships. The other is free topo maps, added in COROS's September update. Its race battery makes a marathon look small. On its nylon band it weighs 1.1 oz (32 g), so it all but disappears on the wrist. Its catch is wrist heart rate, which wobbles for some runners in the cold. A chest strap fixes that. It sits in the under $250 band, so a runner shopping under $300 keeps money in their pocket. Read our full PACE 4 review for the long version.

For road runners, the Amazfit Active Max brings free contour maps, room for your own podcasts and battery measured in weeks. What drops out is multi-band GPS, so it's happiest on open roads rather than wooded trails. Streaming music and Garmin's app go too. Garmin's only watch in this band is the Forerunner 165. It's last generation, missing the training feedback that makes a Garmin worth having. Our under $200 page goes deeper.
Stretch to the under $250 band and the PACE 4 adds multi-band GPS to the maps. Garmin's Forerunner 70 sits in the same band. It trades both for free Garmin Coach plans. Want Spotify and Garmin Pay while staying under $300? That's the vívoactive 6, which gives up Garmin's training feedback to get them. Our under $300 page weighs it.
The COROS APEX 4 adds 32 GB of topo maps, sapphire and battery for a weekend in the mountains. Garmin's best answers here are music (Forerunner 170 Music) or multi-band without maps (Instinct 3 AMOLED). In Garmin's current lineup, maps start above every ceiling on this page. Outside Garmin, they arrive under $200. Our under $500 page picks the APEX 4 for runners who also hike.
Price band: under $250
COROS promises 31 hours in its most accurate GPS setting, or 24 with an always-on display. DC Rainmaker tested exactly that combination and saw it drain about 4%/h. That's a pace over part of the battery, not a full rundown. Still, at that rate a marathon takes only a small bite, however slowly you run it.
The GPS is why it wins. Testers lined it up against flagships on trails and through a London Marathon, and the tracks agreed. The Run Testers called it near flawless after six months. Since the September firmware it carries topo maps too. They're non-routable and squeezed into 4 GB, plenty for a city and a few trail systems. COROS's FAQ, oddly, still says the watch lacks full maps. Few maker pages manage to undersell their own product. Keep the screen lit and you'll charge about weekly. On raise-to-wake, testers went 10 to 14 days.
Its weak spot is the optical heart-rate sensor. Most testers, running mostly in warmer months, saw it track a chest strap closely. Winter is another story. The Quantified Scientist rated it poor and thinks it latched onto his step rate instead of his pulse. Owners report the same drift on cold runs. If your zone training happens on January mornings in Minnesota, add a chest strap. COROS's FAQ confirms it pairs Bluetooth straps. On a steady summer run it won't matter.
Our call: buy it if your long days are runs. Look elsewhere if the watch must pay for coffee or stream Spotify. And if you're shopping under $500 for trail weekends as well, our under $500 page picks the APEX 4, and so do we below.

Amazfit promises 25 days between charges, a figure no tester has confirmed. The always-on screen is a different story. At full brightness it lasted 16 days for The Run Testers, well past Amazfit's own 10-day figure for that mode. On raise-to-wake with a few workouts a week, T3 went past 10 days. Owners who add pool sessions and gym work to their runs, screen still on, report about a week. Charging every week or two is normal life with it. It also carries free contour maps with turn-by-turn and 4 GB for your own podcasts. The 1.9 in (48.5 mm) case is big, but it weighs 1.4 oz (39.5 g) without the strap.
The catch is its single-band GPS, which testers split on. On open routes The Run Testers found distance matching Garmin's fēnix 8 Pro and Forerunner 970 closely. Tom's Guide's walk logged 4.55 miles where a phone recorded 6.1. T3 saw routes drift off roads. A phone isn't a lab reference. But the pattern fits single-band GPS: steady under open sky, shakier once buildings or trees crowd the view. On open suburban roads, you'll be happy. If your PRs happen downtown, stretch to the PACE 4.
Our call: buy it if under $200 is a wall and your miles are on the road. Hikers who navigate under trees should skip it; our hiking-with-maps guide picks the APEX 4 for them. More in our Active Max review.

Garmin sells it as an entry watch, and it is one, until you look at the tracks. DC Rainmaker found them virtually identical to a fēnix 8 Pro running multiband. That held on trail runs and even past downtown buildings, a fine showing for single-band GPS. Heart rate stayed close to chest straps. It lagged only as you eased off after an interval.
The reason to buy it shows up every morning. Garmin Coach plans are free, run/walk included. Training Readiness gives a morning read on whether to go hard or back off.
For its best GPS mode Garmin quotes 16 hours. TechRadar's hour of running in that mode used just under 10%/hour of the charge. That pace would empty it long before Garmin's figure. Even so, a typical marathon at that rate still ends with charge to spare.
The catch is everything Garmin removed to hit the price: no maps (breadcrumbs only), no music, no Garmin Pay, no barometer. For a first training plan you won't miss any of them. It's also the better choice if most of your winter miles are on a treadmill. One indoor-only PACE 4 owner saw his fitness metrics stay blank for months.
Our call: buy it if a plan on your wrist matters more than maps. More in our Forerunner 70 review and our beginner's guide.

Garmin's own manual admits what music costs. GPS life drops from 20 hours to 7.5 once the headphones are playing. Enough for a marathon with a playlist. Not enough for an ultra. No tester has measured that music figure yet, so it rests on Garmin's word.
Spotify, Amazon Music and Deezer all download to it, and YouTube Music joined them some months after launch. Apple Music doesn't. Over the Forerunner 70 it adds Garmin Pay and a barometer. TechRadar's chest-strap comparison found its wrist heart rate on the money. Tom's Guide got 3.5 days with the screen always on; TechRadar got about a week.
The catch is headphone dropouts. Owners report music stuttering mid-run. It's a Garmin-wide complaint, seen as far up as the fēnix 8, and no fix is announced for this watch. Garmin's manual says the watch and the headphone antenna need a clear line between them. That can mean moving the watch to your other wrist. The manual also warns that metal and leather bands interfere more than silicone. Results vary by headphone model, so test yours early.
Our call: buy it if your music lives in Spotify and the phone stays home. If you carry the phone for music anyway, the Forerunner 70 gives you the same coaching plans for less. If maps or multi-band matter more, the PACE 4 or APEX 4 serve you better. More in our Forerunner 170 Music review.

COROS rates it at 41 hours in its most accurate GPS mode. On a full day of mountain hiking with navigation running, DC Rainmaker saw it use about 2%/h. That's a projection from one day, not a rundown. But it's a pace that would carry the watch through a whole weekend on the trail. Tom's Guide's reviewer logged 12 days of near-daily running before charging. The gauge still showed 34%. The maps are proper topo with trail names on 32 GB, and owners say they pan without lag. Sapphire and a titanium bezel keep it pristine. At 2.3 oz (64 g) on silicone, owners sleep in it.
The catch comes with a route loaded. The line DC Rainmaker recorded on mountain routes went jagged and straight-edged, cutting the corners off switchbacks. That happened even in the most accurate mode, and no update since names a fix. Total distance stayed close, so your weekly mileage is right. Strava segment hunters will grumble.
Our call: buy it if you're shopping under $500 and the watch must also cover long trail days and weekend hikes. More in our APEX 4 review and our guide to hiking watches with maps.

Most of this year's news is already on this page. Garmin's Forerunner 70 and 170 Music arrived in May on Garmin's newer interface. No owner is yet past about three months. The Active Max landed last December. The PACE 4 gained its maps by firmware in September. Any review older than that saying "no maps" is out of date. One new watch is worth watching rather than buying.
Price band: under $450
Launched in September, it's the PACE 4 with a bigger, brighter 1.47 in screen. It adds sapphire, titanium, a speaker and 32 GB for maps. Its battery page promises 40 hours in the most accurate GPS mode, or 30 with an always-lit screen. Tested in that always-on setting, DC Rainmaker consistently got projections under 20 hours. No tester has yet drained one from full to empty with that setup. COROS blamed bugs and promised a November fix. Nothing in COROS's release notes through the end of October shows it. When a maker's number and a tester's projection are this far apart, I want the corrected firmware in hand, not a promise. Once the fix ships and testers measure again, it could become the natural step up from the PACE 4. Until then, our call: wait.
Nothing won here on the maker's word alone. Each pick is backed by two separate kinds of proof about that exact watch, with at least one from outside the company. Battery claims were read beside test results at matching screen and GPS settings wherever a test allowed it. The firmware date decided which result still counts. We grouped watches by the price bands a hard ceiling actually reaches. Then we asked what each step up adds.
Yes, though not from any Garmin in these bands. The Active Max has free contour maps under $200, though its GPS gets shaky under trees. The PACE 4 has topo maps in the under $250 band. Every Garmin on this page navigates with breadcrumbs only. Our hiking-with-maps guide explains why that matters at a trail junction.
On open roads, mostly no. The single-band Forerunner 70 kept pace with a multiband flagship in DC Rainmaker's testing, even past downtown buildings. The single-band Active Max didn't convince every tester. Tall buildings and thick tree cover are where multi-band pays for itself. The PACE 4 is the cheapest pick that has it.
Three picks have a tested GPS pace: the PACE 4, Forerunner 70 and APEX 4. All three project comfortably past a marathon. The Active Max and the 170 Music with music on rest on maker figures, 64 hours and 7.5 hours. Treat those as promises rather than proof. For your own longest day, try our GPS battery planner.
None of the Garmins in these bands was on Garmin's December 2025 list for its big feature update. That went to the fēnix 8, Forerunner 570 and 970, and Venu 4 and X1. The Forerunner 70 and 170 Music launched later on Garmin's newer interface. Garmin hasn't said how long they'll keep getting new features. The Forerunner 165 is last generation, with only modest updates since 2024. Our Garmin lineup guide covers the full line.
No. Garmin's Connect+ is optional and sells extras; the core training features stay free. COROS and Amazfit charge nothing. Weighing the two big brands? See COROS vs Garmin.

Most watch for the money
For a runner whose long days are runs rather than trail weekends, the PACE 4 is the watch we'd buy with the money. It tracks like a flagship and maps like a hiking watch. It outlasts any marathon you'll run and leaves change in your pocket. Garmin's current lineup has those maps too. It just wants a much bigger check first.

"Measured" means a tester or owner on this exact model. A percent per hour is a pace over part of the battery, so it is a projection, not a rundown. The marathon column is our own reading of the figures in this table, not output from the battery planner. Where no one has tested the exact model, it says "not measured", the same answer the planner gives; no result from a predecessor or look-alike is carried over.

| Suunto Run | under $200 | Dual-band GPS that testers found as clean as flagships on trails, but no maps, plans from Runna and Suunto's own AI plans don't reach the watch, always-on battery measured at 3 to 4 days, and Suunto has already launched the Run 2. For runners who build their own workouts and run downtown, our under $200 page makes its case. |
| Garmin Forerunner 165 | under $200 | Last generation, no Training Readiness or Training Status, no maps. Only for buyers who want Garmin Pay at the lowest band. |
| Garmin vívoactive 6 | under $300 | The cheaper route to playlists and Garmin Pay, but no Training Readiness, no barometer and single-band GPS. For a runner, the 170 Music is the better music watch if the budget stretches. For the least money on music and payments, our Garmin lineup guide and under $300 page pick it. |
| Garmin Instinct 3 AMOLED (45 mm) | under $350 | Buttons only, multi-band and an LED flashlight, with always-on battery that testers found in line with Garmin's figure, but breadcrumbs instead of maps. The APEX 4 brings real maps under $500. For a new runner who wants a week of always-on screen and buttons only, our beginner's guide picks it. |
| Amazfit T-Rex 3 Pro (44mm) | under $400 | Routable maps and sapphire, but no lab battery test on this size and a maker page that disagrees with itself. Our hiking-with-maps guide covers it for slim wrists. |
| Polar Vantage M3 | under $500 | Multi-band and maps, but maps load via a computer, no full GPS runtime has been measured, no music or payments, and testers and owners split on its GPS. The APEX 4 does maps better in the same band, and its battery has the stronger evidence: 12 days of near-daily running with 34% left, and a dual-frequency pace that projects to a whole weekend, though that pace comes from one long day rather than a full discharge. |
| COROS PACE 3 | under $250 | Last-generation COROS with no maps and a 15 h dual-frequency claim that no tester has run down in that mode; its only lab battery result, from 2023, was in smartwatch mode. Its GPS and heart-rate testing also dates from 2023 firmware, and it was the model hit hardest by COROS's May 2026 update failures (COROS replaced failed watches). The PACE 4 replaces it. |
| Garmin Forerunner 170 (non-Music) | under $300 | Garmin Pay, barometer and power-meter support over the Forerunner 70, but no battery test on this edition; most runners here should take the 70 or the Music edition. |
| Samsung Galaxy Watch Ultra (2025), 47mm LTE | under $700 | Above every ceiling on this page and Android only. Lab results so far come from the 2024 watch, so whether the 2025 watch lasts a marathon in multi-band is not measured. |
DC Rainmaker wears watches side by side against multi-band references and chest straps, and logs battery as a percent drop over long workouts; he supplied the PACE 4, Forerunner 70, PACE 4 Pro and APEX 4 figures above, and the 2023 PACE 3 results. The Quantified Scientist correlates heart rate against a Polar H10 across running, cycling and lifting, and tested the PACE 4 in winter. The Run Testers use several runners per review against flagship tracks, and wore the PACE 4 for six months. Tom's Guide, TechRadar and T3 report weeks of wear rather than a fixed protocol, and Tom's Guide's Active Max walk was compared against Strava on a phone. Gadgets & Wearables restates Amazfit's 10-day always-on figure for the Active Max. OutdoorGearLab buys its units and runs GPS battery down and known-course distance tests. Owner reports come from Reddit threads read by our research agent, counted by person and flagged where the exact model wasn't stated.

| Forerunner 170 Music battery | 3.5 days (Tom's Guide, always-on) against about a week (TechRadar, screen setting not stated) | Consistent with Garmin's own always-on and raise-to-wake split |
| Active Max always-on battery | 16 days (The Run Testers, full brightness) against about a week (owners who swim, lift and run with the screen on) | The gap comes from how much each wearer swam, lifted and ran with GPS on; either way, expect a week or more between charges with the screen lit |
| APEX 4 heart rate | Most testers found it close to a chest strap; one of The Run Testers' two runners saw high readings and spikes after stops | One wrist; a strap settles it for aid-station stop-starts |
| Garmin's platform | DC Rainmaker's December 2025 list named the fēnix 8, Forerunner 570 and 970, and Venu 4 and X1 for the full feature set | No Garmin in these bands was on it, and Garmin has published no update horizon for any of them |
