OK, not as bad as that.

1. Need to change the tile URL (/tile/ -> /tile-auth/) in code
   
2. User needs to be logged into Strava, then:
   
3. User needs to hit https://heatmap-external-c.strava.com/auth once, which grants a 10 day Cloudfront cookie, now heatmap will work.
   
   

Guessing this was a response to Strava's privacy malarky last year.

Thinking of how this flow can be wrapped up into something user-friendly..
