Parramatta, Australia · Monday 28 September 2026
Held in Parramatta in Western Sydney, the Three Bridges Run takes place along the Parramatta River in a setting that combines accessible urban trails with genuinely pleasant riverside scenery. The course winds through George Kendall Riverside Park, Meadowbank Park, Rhodes Point, and Newington Nature Reserve, making use of the Parramatta Valley shared use path. This is working-class Sydney at its best, where the river cuts through the landscape and the race brings together the local running community in a way that feels genuine rather than manufactured. The course is hilly enough to demand respect, with 683 metres of total elevation gain spread across the 42 kilometres, though the elevation itself stays modest at no more than 23 metres above sea level. Runners will find themselves on trail terrain that's mostly runnable but with enough undulation to keep things interesting throughout. It's not a fast course by any means, and that seems to be the point. The race attracts runners of all abilities, from people chasing times to those out for a day on the river, and the mixed terrain and constant rolling hills suit that kind of event better than a flat, quick course ever could.
