Question Of Lust innit

It's a question of lust

It's a question of trust

It's a question of not letting

What we've built up

Crumble to dust

It is all of these things and more

That keep us together

Not *that* great in my case, obviously :)

"Either one is right or the other is". Er...no. In all likelihood they're probably both a bit inaccurate but use different processes to analyse the data in differently wrong ways.

FWIW my Fetch upload, direct from my Garmin 610, does sometimes differ from the source, especially in relation to the pace calculation.

Be that as it may, Glenn, one can't duck the nagging suspicion that strava is Just A Bit Wrong.

Oh, don't get me wrong, it's probably a pile of festering possum droppings. I'm slightly puzzled as to why anyone is using it.

It has a sort of Conquercise-ey thing which is quite snazzy. One defines 'lumps of road' ('segments' in STRAVA-speak) which one can 'race' against other users.

So it IS just a pissing contest for those amongst us needing to assert some trivial superiority over others in a public way to bolster their flagging self-worth but who don't post on Smell.

I shan't be waving my willy on strava any time soon.

Basically yes, Nell. Both paragraphs.

There used to be talk of differing GPS stats comparing the Garminunit, the old Garmin training centre, Sporttracks, Runfriedonionsonsaturday and Fetch.

All will take the gpx data produced, but all will translate it in different ways. So if you run for a mile one device/training software may take the data from the gpx every 3 seconds, the other 5 seconds, the other 10 seconds, or it may take the data by distance - every 5 metres, every 10 metres, every 50 metres etc.... The gamin unit itself will also only poll the satellites every few seconds and isn't in permanent contact. This basically means that each device/piece of software will present the data slightly differently.

If you had a wheel sensor speedo perfectly calibrated it'd probably show a different max speed to that of a gps device (probably higher max speed than the gps device).

Does this help or am I missing the point?

Not quite sure how an activity can be longer on strava though!

About This Thread

A sort of 'Why FetchEveryone is better than STRAVA' wire.
----

Last Sunday I cycled to church.

My Fetch log, which I trust beyond all possibility of doubt, tells me this:

17.07 miles, 1h19m46s, max speed 30.3mph

Garmin Connect, which one assumes is closest to the raw data, tells me this:

17.07 miles, 1h19m46s, max speec 30.3mph

This makes me very happy.

Now, gentle Fetchies, you may have seen or read or experienced strava recently, and been tempted, as I was, to 'dabble' and see whether it might be fun. strava taking data from the same source (my Garmin EDGE 800) tells me this.

17.1 miles, 1h20m48s, max speed 31.9mph

Interesting, eh?
