Best 3 sBest 5 s

Share of peak speed retained over the best 3 s and 5 s windows. Higher suggests the top speed was held more consistently.

For orientation only: shorter GCT/VO and higher LSS are scored upward. This is not a validated performance score.

Session ledger

Performance numbers only

Stryd-only origin marks the introductory 24 Jul session without a matched Polar workout. Stryd mechanics means a usable second-by-second mechanics stream; when shown, n is the number of valid near-top-speed mechanics rows behind the session median. Stryd summary means the activity was matched to Stryd, but only speed/power channels were usable.
