Strava and Elevation Calcs

[Coggy]

Did a 51 mile organised ride on Sunday with a total elevation gain of 1,750 ft according to Strava. This elevation is the same as others in my group that also used Strava.

Now then, have looked at the routes of some others on Strava that did the ride but also used a Garmin Edge 500 or 800 and all of their elevations are 800+ MORE than those of us that just used Strava.

Hope that makes sense. Anyone know which is the more accurate measurement please ?

Strava smooths out elevation on smaller climbs so will always be lower. It always knocks around 25% of my elevation off compared to my gps (I use a Satmap not a Garmin). Download the ride and upload it into ridewithgps and you should see a higher elevation gain

Maybe a stupid question but how do I download the ride please ?

Select the ride you want to download, click on the spanner at the left hand side of the screen and select export gpx

Just found the route on ridewithgps that someone else had uploaded and it is over 300ft more than my Strava App showed.

I've just done last nights commute, Strava gives 1,522 feet, Ridewithgps gives 2,045

That's one hell of a commute !

Fair play

Not the normal route, I deliberately went and did a hill last night on the way home, normally I am lucky to break 700 feet on the ride home

That was a big hill !

@Supersuperleeds getting bored
This is a form of my last ride, the Rider 20 I suspect is very close to what a strava app would give as the elevation is worked from the gps plots, the Edge 705 using a barometric reading is supposed to be more accurate, as is usually born out from the figures, however even a two identical rides i.e. the same route twice can give slightly different corrected figures.

I have used the corrected rwgps since I started so is my base line, however I believe there is a slight problem converting fit files., sometimes the figures are closer than this.

Table on which the above form is based.

As you can see the R20 is usually wrong in the order of 35-45% this i suspect is pretty much what the app would give you. the Edge 705 usually less than 10% .

The Edge 200 will give about the same figures as the R20 I believe.

This should also bring an end to which is more accurate a smart phone app or a true dedicated gps unit, but I doubt it will.
