Parramatta, Australia · Sunday 28 September 2025
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.

This is a very challenging course with 683m of total elevation gain — significantly more than the average trail marathon. The route ranges from 0m to 23m above sea level (23m range). Hill training is essential, and runners should expect a significantly slower time compared to a flat course.
Three Bridges Run is a trail race, meaning the course includes unpaved surfaces such as dirt, gravel, or forest paths. Trail surfaces are inherently slower than road courses due to uneven footing, technical sections, and often steeper gradients. Trail-specific shoes with good grip are recommended, and runners should expect a finish time 10-20% slower than their equivalent road marathon time.
Our difficulty rating for Three Bridges Run is calculated using a model that combines elevation gain, temperature impact, and surface type. Use the difficulty calculator above to enter your target finish time and see exactly how many minutes this course would add or subtract compared to a perfectly flat, cool, road-based marathon. Faster runners and slower runners are affected differently by the same course conditions, so the difficulty is personalised to your pace.
