Bum Run

Bum Run, branded as Bumrun, is a charity 5K walk and run focused on raising awareness of colorectal cancer screening and prevention. Rather than being a single one city event, it is presented as a multi city Canadian series, with annual races in places such as Toronto, Calgary, Halifax, and Vancouver. The official Bumrun site describes it as a nationwide effort to encourage screening, support colorectal cancer charities, and bring communities together around a cause driven event rather than a purely competitive race.
