Brisbane is the capital of Queensland and the third-most populous city in Australia, with a metropolitan population of approximately 2.6 million residents. The city is known for its youthful and multicultural demographic; approximately 33% of its residents were born overseas, with the largest migrant groups coming from New Zealand, England, and China. According to recent census data, Indigenous Australians (Aboriginal and Torres Strait Islander peoples) represent about 2.4% of Brisbane’s population. The median weekly household income in Brisbane is approximately $2,100 AUD. Geographically, the race is held in South Brisbane, a cultural hub characterized by its riverside promenades and the South Bank Parklands, providing a flat and fast paved surface for the looping course.
The event supports Dreams2Live4, a charity that grants dreams to adults living with metastatic cancer. Registration remains open, though price increases are scheduled to take effect five days from today. For marathon participants, the course begins with a 2.2 km out-and-back segment followed by eight 5 km loops. The "Midnight Marathon Mates Run" offers two variations: a "Run Together" format where both runners complete 21.1 km simultaneously, or a "Dual Relay" where they run consecutively. For technical information or charity partnership details, participants can contact the organizers through the official Run The River Events website or the Race Roster platform.
