I've been commuting for ages but only recently started riding recreationally, so some friends recommended I get Strava, which I've downloaded to my iphone 5. As I've only just started using it I'm running it parallel with my Garmin 305.
As my iPhone has proper gps I was surprised to see discrepancies:
Garmin: 25.5 km total, max 70 kph
Strava: 26 km total, max 88 kph
Anyone have an opinion on which is the most accurate?
And how fast is too fast on a bike? I nearly soiled myself on a downhill section yesterday.
