Challenges in launching a community-based group walking program for adults affected by cancer.

Walking is one form of physical activity (PA) individuals affected by cancer have indicated strong preference for and interest in, regardless of disease or treatment status.

Over the span of six months, we were unable to meet targets for peer-leaders (to lead the walking groups; n = 5 self-identified) or participants (n = 0 self-identified; n = 3 recruited via peer-leaders).
