Ground Contact Time
Ground contact time measures how long each foot stays on the ground per step, often in milliseconds from wearables. Trends at fixed pace help spot form or fatigue changes.
Ground contact time is how long your foot stays on the ground each step, often reported in milliseconds by watches and foot pods. Shorter contact at the same pace can reflect stiffer, more elastic running—but surface and speed change the baseline.
Track trends on repeatable routes rather than chasing a universal millisecond target.
Common questions
-
Does shorter ground contact time always mean better running?
Not always—surface, shoes, and speed change the number. Use trends at similar paces; sudden spikes with fatigue can signal form breakdown or under-recovery.
