Garmin Running & Triathlon Watches Compared

Garmin refreshed its entire Forerunner lineup in 2025 and 2026, and the old advice — “just get the 265 or 965” — is out of date. The current lineup is the Forerunner 70, 170, 570, and 970, and each one targets a genuinely different kind of athlete: pure runners who want simple and light, runners who want a few smart extras, and triathletes who need real multisport tracking.
The single most important thing to know before you shop: not every Forerunner supports triathlon multisport tracking. The 70 and 170 are running-focused watches — the 170 adds open-water swim tracking, but neither is built as a true multisport race watch. The 570 and 970 are both marketed explicitly as running and triathlon watches, with auto-transitioning multisport modes. If you race triathlons, start your search at the 570.
The Short Answer
Forerunner 70 (~$249): The simplest, lightest, longest-battery option. Pure running (and pool swimming) only — no altimeter, no open-water swim tracking, no multisport mode. Best for runners who want Garmin’s training intelligence without paying for features they won’t use.
Forerunner 170 (~$299, or ~$349 for the Music version): Adds an altimeter, Garmin Pay, VO2 max, and open-water swim tracking on top of the 70. Still not sold as a triathlon watch, but a reasonable step up for runners who also swim casually.
Forerunner 570 (~$549.99): The new mid-range triathlon watch. Full multisport support with structured triathlon workouts, AMOLED display, built-in speaker/mic, and 23 activity profiles — but no onboard maps.
Forerunner 970 (~$749.99): The flagship. Everything the 570 has, plus full-color onboard maps, a titanium bezel with sapphire lens, a built-in flashlight, ECG and skin temperature tracking, and nearly double the GPS battery life.

Forerunner 70 — The Simple, Long-Battery Option (~$249)
The 70 is Garmin’s answer to “I just want good running data without the bloat.” It runs the same training software as every other current Forerunner — Training Readiness, HRV Status, wrist-based running power, suggested workouts — in the lightest, longest-battery package Garmin sells. What it drops is the extras: no altimeter, no open-water swim tracking, no Garmin Pay.
Who it’s for: Runners who want Garmin’s core training intelligence at the lowest current price point, and don’t need elevation data, contactless payments, or swim tracking. Not a triathlon watch — if you’re shopping as a triathlete, skip this one.

Forerunner 170 — A Step Up, Still Not a Tri Watch (~$299–$349)
The 170 takes everything the 70 does and adds a barometric altimeter, compass, Garmin Pay, VO2 max estimation, and open-water swim tracking. The Music version adds 4GB of onboard storage for playlists.
That open-water swim tracking makes the 170 tempting for casual triathletes, but reviewers are consistent on this point: it’s not built or marketed as a triathlon race watch the way the 570 and 970 are — there’s no dedicated auto-transitioning multisport mode. Treat the swim tracking as a nice-to-have for open-water training, not a reason to skip the 570 if you’re actually racing triathlons.
Who it’s for: Runners who want elevation data and contactless payments, and who swim casually in open water but aren’t racing multisport events.

Forerunner 570 — The New Mid-Range Triathlon Watch (~$549.99)
This is where triathlon shopping should start. The 570 is explicitly sold as a “GPS Running & Triathlon Smartwatch,” with full multisport support, structured triathlon workouts, and auto-transitions between swim, bike, and run. It adds a built-in speaker and microphone (for calls and voice commands), Evening Report summaries, and 23 activity profiles including some outside the core three sports.
What it doesn’t have: onboard maps. You get breadcrumb-style navigation (a line showing your route), not the full-color topo and road maps of the 970.
Who it’s for: Triathletes and multisport athletes who want real tri tracking and don’t specifically need onboard maps — the large majority of racers doing courses they’ve recon’d or that are well-marked.

Forerunner 970 — The Flagship (~$749.99)
The 970 is the most capable Forerunner Garmin has ever made. It carries over everything from the 570 — full multisport, structured workouts, voice/speaker — and adds full-color onboard maps, a titanium bezel with a sapphire crystal lens, a built-in LED flashlight (handy for early-morning transitions or night trail running), ECG capability, skin temperature tracking, and close to 50% more GPS battery life than the 570.
Who it’s for: Ironman-distance and long-course triathletes who want real navigation on the wrist, ultra-distance athletes who need the longer battery, and anyone who wants the best Garmin makes and doesn’t mind paying for it.

What About the Fenix 8 or Older Forerunners?
Fenix 8: Garmin’s rugged multisport flagship, built more for ultra-endurance and outdoor adventure than pure road triathlon — solar charging options, a tougher case, and even longer battery life than the 970. Worth a look if you want maximum durability and battery beyond what the 970 offers, but it’s a heavier, bulkier watch and a step outside the Forerunner line’s running-first design. We’ll cover it in a separate comparison.
Forerunner 265 and 965 (previous generation): Garmin’s prior flagships, now superseded by the 570 and 970 respectively. They’re no longer the current models, but they still show up at a real discount at retailers clearing old stock — both were excellent watches in their day, with full multisport support and the same core training software as the current lineup. If you see one heavily discounted, it’s not a bad buy; just know you’re getting last generation’s hardware (older display, no speaker/mic, less battery than the current equivalent tier).
Which Should You Buy?
- Pure runner, tightest budget: Forerunner 70
- Runner who wants elevation data + casual open-water swims: Forerunner 170
- Triathlete, want real multisport tracking without paying for maps: Forerunner 570
- Triathlete or ultra athlete who wants maps, max battery, and every feature: Forerunner 970
- Found a discounted Forerunner 265 or 965: Still a legitimate multisport watch if the price is right
The Bottom Line
The days of “just compare the 265 and 965” are over — Garmin’s current lineup spreads much further, from a lightweight $249 running watch with no multisport features at all up to a $750 triathlon flagship with onboard maps and a flashlight. The number one filter is simple: if you race triathlons, you want the 570 or 970. If you’re a pure runner, the 70 or 170 will save you real money without costing you any of the training intelligence that actually makes you faster.
