Thank you for adding the statistics of how many activities and miles contribute to a city! It is awesome. Could you please add the total elevation as well? Some of the cities I run are super hilly, and I would love to see how any feet I climbed while completing the city!
Yeah, Garmin (and I am guessing the other services) track it. Either from an altimeter on the watch itself or from the maps. I am guessing almost all activities have it.
The data in OpenStreetMap doesn’t include elevation, and I don’t store elevation on activity records. I don’t, currently, have any way of showing this data because I don’t have it.
I think this is hard to pull from say Garmin too. Because every watch is different. I know one of my friends always has issues with her altimeter and it will say crazy reading like 100k elevation gain.
