Result differences between Garmin and Strava

When Strava syncs with my Garmin app after an activity, the ave and maximum results achieved are significantly different. For my latest ride, the max speed diff between the two are 2.8km/h (Strava is always lower), and the cadence differs by 3rpm!

Why is there a difference if Strava receives the information from Garmin? Why is the Strava results always lower?

  • Totally agree with this. I also do not know why Strava should changer the times that the device that has recorded the segment submits?? I understand auto pause can effect a time etc but on a flat or downhill effort there is no reason there should be a difference. A few times lately Ive been going out to improve on past efforts and found myself chewing the stem trying to smash a record and then enjoying the rest of my ride thinking I have shaved 2-3 seconds of my PB only to get home and see on upload I was a second behind and the PB not beaten? I also missed out on two KOMs recently after giving huge efforts to take them. Seriously wondering why I pay for premium?

  • As far as i've read. Strava doesn't use the speed or the power information from the sensors.. it calculates the speed and power from GPS data (distance, elevation), so even if you have a power meter.. the strava info is going to be different from whatever the sensors are logging into your device.

  • My response from Strava. Which took weeks for a response I might add. “Garmin devices use a different algorithm for determining when a user starts and finishes a segment than Strava uses, which can affect the elapsed time reported for the segment. To ensure consistency between users, the times shown on the Garmin during an activity are preliminary, and the times shown on Strava after uploading are final.”

    I still don’t understand why there should be a difference! Strava should honour the information Garmin provide and Garmin should use the same algorithm. Bottom line we should be able to trust the information these devices and services we pay for are accurate.
