Footpod confusing measurements while running

[Danyl]

Good afternoon, folks.

While running on a treadmill and using garmin footpod i see confusing measurements. Here is a log as an example connect.garmin.com/modern/a....

Warm up and cool down are at 6 km/h. Footpod and treadmill are giving pretty much the same reading. Then i turn treadmill for 7.5 speed, but footpod still thinks i'm doing more or less 6 km/h.

Why is it? Because step length is shorter while running compared to walking? How do i get a correct readings while running... Do i need to re-calibrate footpod while running?

Sorry for all the confusing questions, but i'm bamboozled here I thought that given correct calibration this thing should be smart enough to give correct readings no matter if you are running or walking...

TLDR: Why do i get correct speed from footpod while walking and incorrect one while running?

Why have you got a footpod?

[Danyl Graduate in reply to John_W]

To get more correct measurements generally and during a treadmill running in particular.

Correct measurements of what exactly?

[Danyl Graduate in reply to John_W]

Primary objective was speed. My Garmin 945 gives absolutely ridiculous speed readings without footpod on a treadmill... like 12-13 km/h when i'm adamant that if i'd go that fast i'd explode

Everything else is a bonus... cadence, stride length etc.

I run on treadmills a fair bit and I have a Garmin FR235 - v popular watch. It rarely gets my distance correct but I'm able to edit the distance in Garmin Connect but not on Strava unfortunately.
