PR · Pace · Heart-rate efficiency
A PR is only useful when you know why it happened.
Onrep looks at distance, pace, heart rate, laps, route, grade, stops, and sensor quality so a faster run has context.

Route and lap comparison
For runners who already have numbers, but still wonder whether a faster split came from fitness, effort, terrain, or conditions.
Running logs become evidence for pace efficiency, route-specific improvement, and more careful PR interpretation.
The problem: faster does not always mean fitter
A 5K PR can come from fitness, downhill help, GPS noise, or simply pushing harder.
Track loops and 1 km splits answer different questions.
The same pace at a lower heart rate can matter more than a flashy PR.
How Onrep makes running records easier to trust
What you can notice after a run
See the character of a PR
Onrep checks whether a PR looks efficient, hard-pushed, risky, context-assisted, or limited by the available data.
Separate laps, splits, and routes
Track loops, 1 km splits, similar courses, and overlapping segments are separated so each comparison stays useful.
Use heart rate as context
Onrep looks for faster pace in the same heart-rate zone and flags when sensor quality or workout type limits confidence.

5:55/km at Z3
Pace improved compared with your earlier baseline in the same heart-rate zone.
Course lap view
Loop repeats and 1 km splits are kept separate.

How Onrep makes running records easier to trust
1
Start from phone or watch
GPS readiness, heart rate, countdown, live pace, lap, zone, and finish controls stay easy to glance at.
2
Let Onrep split the effort
Splits, laps, route candidates, grade ranges, and heart-rate zones become structured detail after the run.

Read the result after finish
The detail page explains whether today looks like efficient progress, hard effort, hidden growth, or a result that needs context.
Run with a record that explains more than pace.
Download Onrep before your next run and see whether the result was fitness, effort, route, or conditions.

A slower day can still be useful when it gives your next run a better baseline.
