Thousands of Wellington walkers, runners and mountain bikers have signed up to a new app, supporting the volunteer network that advocates for and builds tracks in the city's town belt. Trails Wellington is a collective of locals passionate about maintaining and expanding the network of trails around the city. In June the membership app was launched and now has more than 2000 members. Chair of Trails Wellington, Anthony Edmonds, talks with Kathryn about the group's big plans.
