The Activities You Must Complete

These aren’t for the fainthearted and they’re going to take determination and mental strength. We know you’ve got it in you.

The Extra Mile


100km. It’s up to you how to get it done; walk, run, cycle or crawl. Just make sure you get it done within 21 days. You got this.
