FITIV Pulse records GPS from your Apple Watch or your iPhone on every outdoor run, ride, hike, and walk. You see your pace, distance, and elevation gain as you go, and afterward you get the route map and splits next to your heart rate zones and training load. Record with the watch and you can leave the phone at home.
What is GPS Workout Tracking?
GPS tracking uses satellite positioning to record the path you move along. It calculates pace and distance from how your position changes over time, and it combines altitude sensors with GPS signals for elevation. Modern sport GPS systems update your position every second and, with a good signal, can calculate pace to within a few seconds per mile.
For runners and cyclists, that does two jobs. During the workout you can see current pace, average pace, distance, and elapsed time, so you can hold a target pace on a tempo run or check the distance left on a long ride without carrying a separate device. Afterward, the full track gives you a route map, mile or kilometer splits, how your pace was spread across the effort, and an elevation profile. That tells you how evenly you paced a 10-mile run.
How FITIV Tracks GPS Data
Apple Watch GPS Integration
FITIV uses the GPS receiver built into every Apple Watch it supports (Series 4 and later, SE, and Ultra). Apple Watch Ultra adds dual-frequency GPS (L1 and L5) and multiple satellite constellations (GPS, GLONASS, Galileo, BeiDou, QZSS) for improved accuracy. The watch works on its own, so you don't need your phone for outdoor workouts.
During a GPS workout, FITIV records your position continuously and calculates:
- Current pace (updated in real time, displayed in min/km or min/mile)
- Average pace (smoothed over the full workout)
- Distance (cumulative from GPS position changes)
- Elevation (from your Apple Watch location data, smoothed)
- Elevation gain/loss (accumulated throughout the workout)
- Route map (GPS track saved with the workout)
The watch's optical heart rate sensor records alongside GPS, so you get location and heart rate together with no extra hardware.
Pace and Distance Accuracy
Under open sky, Apple Watch GPS distance is typically within 1-2% of actual distance. Accuracy drops in urban canyons with tall buildings on both sides, under dense tree canopy, and at the start of a workout before the watch has a full satellite lock, so wait 10 to 20 seconds outdoors before you hit start. If your route or distance still looks off, the help center's guide to fixing GPS issues in FITIV Pulse covers location permissions and other quick fixes.
When GPS signal is weak (tunnels, indoor tracks), Apple Watch also uses its accelerometer to estimate running distance, calibrated from your earlier outdoor runs.
If you record on a Garmin device, connect Garmin Connect in FITIV (More tab, then Garmin Connect) and your Garmin workouts sync in with their heart rate and GPS. See FITIV + Garmin for setup and what transfers.
Elevation and Climbing Data
FITIV tracks elevation from your Apple Watch location data and smooths it, so small bumps in the signal don't inflate your climbing total. Elevation from any phone or watch can be off by several meters, especially in short or flat workouts.
Climbing adds to the physiological cost of an outdoor session, and FITIV's heart rate-based training load captures that cost because your heart rate rises on the climbs. Each workout summary shows total elevation gain, and you can chart it by week, month, or year on the History tab.
Route Mapping
Every GPS workout gets a route map in FITIV. Open the map from a workout's summary and use the menu to color the route by:
- Heart Rate Zone (the default), so you can see where the hills pushed your effort up
- Pace (or Speed for rides), faster segments in one color, slower in another
- Elevation
- Power Zone, for workouts recorded with power
You can switch the map style, show split markers along the route, and share a workout card with your route map, heart rate zones, and key stats.
GPS Data and Training Load
FITIV's training load comes from heart rate (TRIMP) by default. If you switch the Training Summary to Training Stress Score, rides and runs with power use power-based TSS. GPS doesn't change those numbers, but distance, pace, and elevation show what's behind them. A 60-minute run at 70% of max HR at 5:30/km and the same run at 4:30/km carry similar heart rate load, but the faster pace shows your aerobic fitness improving.
Why GPS Tracking Matters for Runners and Cyclists
The simplest use of live pace is sticking to the plan. Tempo runs tend to drift fast and long runs drift slow, and a pace readout lets you catch it as it happens. Athletes who run with real-time pace display on their watch run their intended paces significantly more accurately than those who run by feel.
Your route history also works as a benchmark. If you have a 5K loop from your front door, run it again at 3, 6, and 12 months and compare your splits: that's a more meaningful performance measure than estimated VO2 max trends, because you simply ran the same course faster.
For cyclists with a power meter paired to Apple Watch, you can switch the Training Summary to Training Stress Score to base load on power and your FTP. GPS adds the route, distance, and elevation profile alongside it.
Frequently Asked Questions
Can I use FITIV for GPS tracking without an Apple Watch?
Yes. FITIV can use your phone's GPS for outdoor workouts when you carry it, paired with a Bluetooth heart rate monitor if you like. With an Apple Watch, FITIV uses the watch's built-in GPS so you can leave the phone at home. Workouts recorded on a Garmin device sync in when you connect Garmin Connect in FITIV.
How does Apple Watch GPS compare to a dedicated Garmin GPS unit for running?
Under open sky conditions, both perform similarly: within 1-2% distance accuracy and sub-second update rates. Garmin devices with multi-band GPS (available in premium models) outperform Apple Watch in signal-challenging environments: urban canyons, dense forest, technical trail switchbacks. For most runners on roads and established trails, Apple Watch GPS is entirely adequate. Elite runners targeting precise split data on technical trails may prefer a dedicated Garmin device.
Does GPS tracking drain the Apple Watch battery significantly?
GPS is one of the biggest battery draws on Apple Watch, and how long it lasts depends on your model. Apple rates its current Apple Watch Ultra for up to 18 hours of outdoor workout tracking with GPS and heart rate, and longer with its Extended Workout modes; other current models are rated for less. Most workouts are well within that. For ultramarathons and very long rides, Apple Watch Ultra gives you the most room.
Can I see my running routes on a map after the workout?
Yes. Every GPS-tracked workout generates a full route map viewable in FITIV. You can color the route by heart rate zone, pace or speed, elevation, or power zone, and you can share a workout card with your route map, heart rate zones, and key stats.
