RUN COMPARISON
How to compare two runs on the same route
A useful comparison starts with a question and a fair baseline. Here is how to read two runs together without letting one number decide the answer.
Choose the question first
“Was I faster?” and “Did the same pace cost less effort?” are different questions. The first needs a comparable distance and time. The second needs more context, including heart-rate coverage, route and recording conditions.
Choose runs with a similar purpose. An easy run and an interval workout can share a route while asking very different questions. Check that both activities use the same distance units and that you are comparing moving time with moving time, or elapsed time with elapsed time.
A worked 10K comparison
The following numbers are illustrative. Both runs cover exactly 10 kilometers. Heart-rate cost here is average heart rate divided by average speed in meters per second.
| Measure | Run A | Run B |
|---|---|---|
| Moving time | 50:00 | 49:00 |
| Average pace | 5:00 min/km | 4:54 min/km |
| Average heart rate | 150 bpm | 155 bpm |
| Heart-rate cost | 45.0 bpm/(m/s) | 45.6 bpm/(m/s) |
Run B is one minute faster, but its heart-rate cost is slightly higher. Those observations can both be true. They describe these two recorded efforts; they do not establish whether the runner became fitter between them.
Look inside the averages
Inspect the pace and heart-rate charts. Did the runner maintain the effort, change pace halfway, stop at crossings or lose sensor readings? Compare similar sections before explaining a difference in whole-run averages.
Then check the route, elevation, recording source and notes about conditions. A comparison becomes more useful when you can see what differs, including the information that the recording does not contain.
Use the comparison in Runome
Runome supports activity filtering and run comparison. Choose a suitable pair from your history, inspect the core metrics and then review the detailed streams that are available. Metric availability depends on the source data; a missing value is a reason to check the inputs.
Repeat the comparison with other similar runs before drawing a wider conclusion. Use the pace calculator to check the time and distance arithmetic, and the metric reference to understand what each measure represents.
