Best Garmin for Swimming and Running
Compare the best Garmin watches that track both swimming and running — pool laps, open-water GPS, multisport mode, and Training Readiness in one device.
If you split your week between the pool and the road, you do not need two watches — you need one that handles both sports without faking the metrics. These five Garmin models track pool laps, open-water GPS, running pace, and Training Readiness in a single device. The trap most buyers fall into: grabbing a watch that excels at running and assumes swimming is just "waterproof and counts something." The Forerunner 165, for example, tracks pool laps accurately but has no open-water mode.
The Fenix 8 covers everything but weighs more than some smaller wrists can handle. The right pick depends on where you actually swim, how hard you actually run, and what battery life you need to survive a long training weekend. What a dual-sport watch needs to do The 5 best Garmin watches for swimming and running Which pick actually wins? For most swim-run athletes, the Forerunner 265 is the cheapest watch that does both sports competently: pool laps, open-water GPS, training readiness, and structured workouts from AquaPlan — for $449.
The display is bright, the metrics are honest, and it does not pretend to do things it cannot. Step up to the Forerunner 965 if open water is a regular part of your training and you want the multi-band GPS to stop drifting in choppy water. The titanium bezel and topographic maps are the visible upgrades; the satellite fix is the actual one. The Fenix 8 is the right call only if your swimming and running overlap with hiking, climbing, or full-day outdoor sessions where battery life and ruggedness matter more than weight.
Otherwise, you are paying a premium for a watch that does the same swim and run metrics as a 965 at 50+ grams on your wrist. The Forerunner 165 at $349 is the honest budget pick — pool swimming accurate, running metrics solid, but no open-water GPS. If you never leave the lane lines and you do not need barometric elevation for your runs, it does the job and saves real money.
The newest Forerunner 970 is the flagship buy if you want the latest sensor stack, ECG, and Running Power From Wrist in a single watch. It shares the multisport bones of the 965 with a newer heart-rate sensor and additional metrics that quantify endurance rather than just pace. How to use a dual-sport Garmin with AquaPlan The watch tracks; AquaPlan plans.
Build a pool session in the workout generator, set your send-offs by pace or CSS zone, then export a .FIT file and sync it to your Garmin watch. Your intervals, rest, and target pace load into the pool activity profile — swim, press start, and the watch takes over from there. Build a run session the same way, and the structured workout lands in your running profile with pace and HR targets that match your Training Readiness score.

Build swim and run sessions that load to your Garmin AquaPlan's workout builder exports structured .FIT files for pool swims and runs. Your intervals, rest periods, and pace targets land on the watch ready to swim or run.
Frequently asked questions Pick by where you swim, not by the highest price tag. A Forerunner 165 in the pool beats a Fenix 8 you never take outside, and a 265 with a clear training plan outperforms a 965 you forget to charge.
