‘The Flinders Running Festival is all about getting out and having fun.  It started in 2007 as a community fun run and health promotion day and has grown every year since.  Now we have the Pub2Pub 26k walk/run and the  followed by the FIAAI Flinders 5, a 5 km event. For those of you arriving on Friday and want a fun and casual warm up run, we also hold a free 5km untimed run at 3.30pm starting at Trousers Point.
 
The festival is still very much a community weekend encouraging as many people to participate at any speed, pace or gait they please.  We encourage pram pushing and dog running in the FIAAI 5 and the Pub2Pub 26km.  
​For many local families it's a way of getting together and celebrating Father's Day.  There are no time restrictions or expectations for those who like to take their time but there is plenty of competition for runners who like to test themselves.  And of course there is plenty of opportunity for good food, great views and inspiring conversations!’
