The hikes/walks need to be with the intention of getting in miles or an adventure and not your regular daily activities. Our challenges are not simply to accumulate miles/steps, so do not count your regular daily activities. As much as we prefer you hike on a dirt trail, we realize that is not always possible. So urban hikes and paved paths are allowed. Our primary goal with our Challenges is to get people outdoors and outside of their own neighborhood/surroundings to enjoy nature while hiking.
