^^ Accurate to around 5%.
I've been on rides where strava's estimates have to have been over 200% the real figure for ten whole minutes.
I don't use it much now but there's vast differences between my power meter data and Strava's guesses. Strava is a ride logger on steroids, not a replacement for HRMs and power meters.
