Strava
Strava combines activity recording, training insights and a community for athletes.
Product overview
Strava brings together recorded runs, rides and other activities with route exploration and training analysis. Upload compatible device data to inspect distance, pace, elevation and changes in performance over time.
Service tools add features such as route planning, segment leaderboards and deeper training views. Heart-rate or power analysis requires the corresponding sensor data; the service cannot recreate measurements the device did not record.
A Strava service is separate from a Runna training-plan bundle unless that bundle is explicitly included. Route and leaderboard availability can vary, and the service does not replace a GPS device, a sensor or individual coaching.
