London 100 walking challenge

Londoners can sign up for a free month-long challenge to walk 100 miles in May, starting on May 1. (nationalparkcity.london) The event runs from May 1 to May 31, 2026, and is organized by London National Park City with Go Jauntly, a walking app that tracks miles and shows local routes. (nationalparkcity.london) Participants join through the Go Jauntly app, where the challenge logs progress toward 100 miles and unlocks milestone badges, daily prompts and curated Walk London routes. (nationalparkcity.london) The individual target sits inside a bigger citywide push: organizers say they want London to log one million miles during the London Walking Festival in May 2026. The festival site says it will feature more than 200 guided walks across the capital. (nationalparkcity.london, nationalparkcity.london) The campaign is built to be flexible rather than all-or-nothing. Organizers say every mile counts even if walkers do not reach 100, and the app tracks both personal totals and the wider collective tally. (nationalparkcity.london) London National Park City says the challenge is also meant to measure behavior change, using pre- and post-challenge surveys alongside app activity data. Go Jauntly markets similar walking challenges to councils and transport agencies as a way to encourage more walking. (nationalparkcity.london, gojauntly.com) The May challenge builds on earlier London walking campaigns run through Go Jauntly, including a 2023 Transport for London challenge that asked people to walk at least 20 minutes a day during May. (gojauntly.com) This year’s version raises the bar from daily minutes to monthly miles, while tying the target to a festival-wide count across neighborhoods, parks and riverside routes. Registration is already open ahead of the May 1 start. (walks.gojauntly.com, nationalparkcity.london)
