Garmin Connect and Strava dealing with an obvious anomaly

by Daveyraveygravey   June 29, 2014  

Did a nice ride today aimed at two of the 100 hills in Kent/Surrey. Flew down Titsey Hill - it was early and quiet - but really surprised when my Garmin Forerunner gave my vmax as 109 mph! Put it down to maybe hitting a bump or a swerve causing a spike in the data or machine.
Uploaded data to both Strava and GC. GC still shows vmax as 109 but not surprised as it is a Garmin device. Strava shows vmax as 84 kph which makes more sense - most of my fast downhills have been around 53 mph and doubt me and my bike can get much more than that - not that I want to! When I check the segment for that hill the average speed is 86 kph but max is 84. How does that work?!

It'll be off GPS. Titsey's got loads of tree cover so will be a bit glitchy when it comes to finding satellites - basically you'll have jumped between two blind spots very rapidly.

Correct Altitude.


Can be as much as 300ft+ difference between the two over a flatish ride of say 2000ft over a 50 mile ride.
