The dust has settled, the pollution ebbed and flowed, and our Strava challenge has come to an end.
We challenged every London runner to get out, run 5k, and use our Clean Air Tracker to help us plot a map of London's cleanest routes.
We've been busy collating the results, separating the dirty from the clean, and mapping a series of curated runs to help you avoid pollution in the Big Smoke.
We've got some exciting news coming about our Clean Air Tracker, but without any further ado, below are the runners who found the cleanest routes in their borough. Congratulations to every one of you! If your name and run is below, get in touch with us to claim to prize!
