Garmin & Strava do not agree

[Milkfloat]

Yesterday I planned a route on Strava, then I followed it exactly. Despite riding into a headwind the whole way, I was surprised by the ease of the ride. When I checked the ride data on Strava it seems the planned route had half the climbing than reality.

I did a 40 mile ride today and Strava told me I did 0 miles

Then it didn't happen. Strava never lies.

Normally you would be right.

But I also recorded it on Garmin and uploaded it to Strava. It won't defeat me!

Its not a question of accuracy but one of maths.

I wouldn't be surprised if garmin connect actually used it's own stopped time calculation separate from what is set on the garmin device. I don't use the auto pause most of the time so I can't test it. But will when I use it again.

Never looked actually. I flick through data before I upload and know by default that on strava it will be a bit slower. I only upload to GC because theres no choice when the Edge1000 wifi configured, but it also means automatic sharing and totally wirefree/pcless uploads

There's no such thing as an "accurate" moving average. There are different algorithms that come up with different results. Just like different algorithms come up with different results for calories burned.

It's just a vague hand-waving indication of general fastness, not a real speed.

The algorithms should be precise though, in that they will give repeatable results and you can compare the results of that algorithm for different rides.

Just out of interest
Ride 11/7 18.2avg GC - 18.0 Strava
Ride 12/7 15.7avg GC - 15.7 Strava
Ride 14/7 18.4avg GC - 18.3 Strava
Ride 15/7 15.9avg on both GC+ Strava

I can totally live with this, but should really check the history on the garmin itself but it's downstairs and I'm not moving

Checked my Garmin history and it shows the same as connect. That was looking at actives that have both auto pause and those that don't.
