The Busselton Runners Club Half Marathon & Fun Run is held annually in February, and has grown from 220 participants in 2009, the first year, to over 1100 participants in 2015. It includes a 21.1km half marathon, 10km and 5km events.
In 2017 the Busselton Half Marathon will be raising money for FAWNA. FAWNA is a not for profit rescue and rehabilitation organisation for sick, injured and orphaned native fauna. Operating in the south-west of Western Australia, FAWNA is entirely run by volunteers and funded almost entirely by donations.
