How it is calculated
HSR distance = Σ distance where speed > HSR threshold
The app adds up the distance covered at every moment the player's speed was above the HSR threshold.
HSR includes sprint distance: anything above the sprint threshold is also above the HSR threshold.
The default is the Senior preset. Age-group presets from U6 to U21 use lower speeds, and staff can switch a team to percentage-of-max mode, where HSR starts at 55% of each player's own top speed.
How to read it
HSR shows how much of a session was run at speed. Watch it alongside sprint distance and total distance: two sessions can cover the same ground with very different amounts of fast running.
One player's speed, minutes 32 to 40
| Top speed | 30.4 km/h |
|---|---|
| Seconds above the sprint threshold (15.8 km/h) | 15 |

Questions
Why is the HSR threshold lower for youth teams?
Younger players run slower in absolute terms. The age-group presets lower the speed thresholds so that high-speed running means the same effort for a U12 as for a senior player.
