For this challenge anything goes! You can choose to fly solo or unite as a team (either with your household or remotely through the app) to walk, run, push or wheel the 20km challenge all in one go or over a few days from your living room, garden or neighbourhood. The choice is yours! Just remember to don your Superhero outfits and capture your finish line moments to share with everyone! Make sure you stay connected and super-active!
