Quick Answer
The fastest way to measure a run you’ve already done is to retrace it on a free online map tool like On The Go Map or Plot a Route. For future runs, use a GPS watch (most accurate, ±1–2%) or a phone app like Strava, MapMyRun, or Nike Run Club (±2–5%).
5 Methods Compared

| Method | Accuracy | Cost | Best For |
|---|---|---|---|
| GPS running watch | ±1–2% | $150–$500+ | Most accurate wearable option. Tracks in real time. Works for every run. |
| Phone running app (Strava, MapMyRun, Nike Run Club, Runkeeper) | ±2–5% | Free | No extra device needed. Good enough for most runners. GPS accuracy varies by phone model. |
| Online map tool (On The Go Map, Plot a Route, Mappedometer) | ±1–3% | Free | Best for measuring a run after the fact. Trace your route on a map and get exact distance. |
| Google Maps ("Measure distance" feature) | ±2–5% | Free | Quick and available everywhere. Less smooth than dedicated tools but works for basic checks. |
| Car odometer | ±2–3% | Free | Old-school but reliable. Drive your route and note the distance. Best for pre-planning routes. |
Already Finished Your Run? Use an Online Map Tool
If you’ve already run and didn’t track the distance, your best option is a free online mapping tool. These let you trace your exact route on an interactive map and calculate the total distance as you click.
On The Go Map (onthegomap.com) — the simplest to use. Search your starting location, click along your route, and the distance updates in real time. You can switch between miles and kilometres and see elevation data.
Plot a Route (plotaroute.com) — more features including auto-snapping to roads, elevation profiles, and the ability to save routes. Their “How Far Did I Run” tool is built specifically for this purpose.
Google Maps — right-click your starting point on desktop, select “Measure distance”, then click along your route. It’s slightly clunkier than dedicated tools but always available.
For Future Runs: GPS Watch or Phone App
If you want distance tracked automatically on every run, a GPS device is the way to go. A GPS running watch (Garmin, COROS, Polar, Apple Watch) is the most accurate option — dedicated GPS chips and multi-satellite connectivity (GPS + GLONASS + Galileo) deliver ±1–2% accuracy on open paths.
If you don’t want to buy a watch, free phone apps like Strava, MapMyRun, Nike Run Club, and Runkeeper use your phone’s built-in GPS to track distance. They’re slightly less accurate than dedicated watches (±2–5%), especially in urban areas with tall buildings or on trails with heavy tree cover, but they’re good enough for most training purposes.
Quick Distance Estimates from Steps
If you only have a step count from a pedometer or basic fitness tracker, you can estimate distance:
Running: roughly 1,400–1,700 steps per mile (depending on height and pace). Walking: roughly 2,000–2,200 steps per mile. As a quick rule of thumb: divide your step count by 1,500 for an approximate running distance in miles, or by 2,000 for walking.
FAQ: Measuring Your Running Distance
How can I find out how far I ran?
Use a free online mapping tool like On The Go Map or Plot a Route to retrace your route. For future runs, use a GPS watch or phone app like Strava.
What is the most accurate way to measure running distance?
A GPS running watch — typically accurate within 1–2% on open paths. For official race certification, a calibrated Jones counter on a bicycle is the gold standard (±0.1%).
Can I measure my run distance on Google Maps?
Yes. On desktop, right-click your start point, select “Measure distance”, then click along your route.
How accurate are running apps on my phone?
Generally within 2–5%. Accuracy depends on your phone model, satellite reception, and surroundings. GPS watches are slightly more accurate.
How many steps is a mile?
Running: roughly 1,400–1,700 steps. Walking: roughly 2,000–2,200 steps. Divide your step count by 1,500 (running) or 2,000 (walking) for an approximate distance in miles.
Pick a Method and Start Tracking
Knowing your distance matters — it’s how you set goals, track progress, plan training, and know when it’s time to replace your shoes (most last 500–800 km). The method you choose depends on your budget and preferences, but even the free options are accurate enough for meaningful tracking.
Once you know your distances, our coaching programmes help you structure your weekly mileage with purpose — easy runs, speed work, long runs, and recovery all in the right balance.
