TENZING Clean Air Challenge

Help map clean runs in the big smoke.

Challenge Ended: January 29, 2020
(Don't forget to tag your runs with a #TenzingClean5k to be eligible for the grand prize!)

You can't beat running in nature and breathing in fresh air. But is it still possible to run clean in the Big Smoke? We've partnered with King's College London and Strava to build the TENZING Clean Air Tracker that uses realtime data and the latest technology to find out just that. We're challenging everyone in London to get out, run 5k, and help plot a map of the cities' cleanest routes. Sign up at tenzingcleanairrunclub.com to sync your Strava profile and get realtime pollution scores for your runs, free and forever (you're totally welcome).

To complete the challenge, all you need to do is run 5k. But if its honour, glory, and a 3 month supply of TENZING Natural Energy you're after; you'll need to find the cleanest route in any one of London's 32 Boroughs.

Remember, the higher your score, the cleaner the run... and, don't forget, you'll need to have run with the TENZING Clean Air Tracker, and tagged #tenzingclean5k in your activity title to be in with a chance of winning. You can join TENZING's weekly Clean Air runs in London too! Join our club to find out more.
