Strava Cadence
-
I did my 2 first activities with the Watch.
The cadence value is 2 times the value i can see in the Suunto app. Anyone having the same issue?IMG_2641.png

@Lieven-DB I do not use Strava, but my guess here is that since the Suunto Run watch is so new they haven’t had the time to correctly examine and parse the uploaded .fit file at their end. Instead of using an ‘rpm’ field (and doubling it), they pick a ‘spm’ field and incorrectly double that.
The whole Cadence issue in running is rather silly. Below is a screenshot of my latest trail run, with the English abbreviations (from a Suunto Race S):
RPM stands for ‘Revolutions per minute’ while SPM means ‘Steps per minute’. Now, RPM comes from the biking world and has absolutely no business to pop up in our running data! But it was ever thus… On my first Garmin watch, the Forerunner 70 (foot pod, no GPS), Cadence was displayed as RPM, exactly like it is now on the Race S. Sigh… So two steps form a full ‘Revolution’, and let me Sigh again… On the next watch I bought from Garmin - the GPS watch FR620 from 2013 - they tried to accommodate runners by exposing a doubled value on the watch (the SPM) while still writing the RPM to the .fit file. Due to having to remember this doubling acrobatics ‘forevermore’ the Garmin coders regularly introduce Cadence related bugs. In fact, even on my FR955 with a firmware about a year old, a Cadence field starts to show an RPM value instead of SPM now and then. The same bug exists on a FR630 from 2015 - I tried it out a month ago…
As for Strava, send them a bug report. It is their responsibility to correctly parse the uploaded data.

Everything that is at least half way scientific, will measure the period of some continuous movement, not half a period.
So for me the full cycle left foot to left foot make most sense. -

But seriously, you won’t find any running instructor talking about Cadence in the RPM sense. Even Suunto with this Run watch has implemented a metronome with a Cadence advice of:https://www.suunto.com/sports/News-Articles-container-page/run-with-the-new-suunto-run-gps-watch/
“Metronome
Cadence – the number of steps you take per minute – is a great indicator of efficient running form. Use Suunto Run’s metronome to maintain your target step frequency. A cadence of around 180 steps per minute is commonly recommended.”I myself would say ‘try to keep it above 170 to minimise heavy pounding steps’.
