Formerly known as Duncan's Run Hundred, Duncan's Run is held annually in honour of Duncan Orr who tragically died in 2013. Duncan was an influential member of the Traralgon Harriers Athletics Club and is greatly missed by the local community.
A new course has been made for 2017 that incorporates trails used previously, mixed with some exhilarating new ones. The main event will be the 50km solo/relay with a 21km and 6km held in support. The 100km race will not be held in 2017.
