Please note that when you are using this Strava layer that there is no actual permission to use the data and you are running the risk of having your edits removed if there is trouble down the road (and that is why you need to use hackish workarounds to access the layer in the 1st place).

You probably should start off the post with WHY you would want to do this. What benefit does this give the user?

@SimonPoole I think Strava is pretty OSM friendly, they use OSM after all. It may be worth reaching out to them to get confirmation.

@CjMalone this has been tried numerous times and the result has been the non-commital statements we’ve receive to date (not an outright no, but not an outright and clear, official “yes” either).

@SimonPoole The OSM Wiki says that the Strava Heatmap can be used for tracing and that they gave an explicit permission. If you are sure that this is not true, please update the Wiki.

This plugin has been working excellent the last months but now it seems to have stopped. Can you look into it to see what has changed? Thank you!

Oops, never mind, today it decided to start working again. Thank you!
