Sydney International Regatta Centre 5K, 10K & Half Marathon 2026

The Sydney International Regatta Centre 5K, 10K & Half Marathon is a RunThrough Australia event held at the Olympic rowing venue in Penrith, located approximately one hour northwest of Sydney CBD. The race takes place in July and offers participants three distance options: 5 km, 10 km, or 21.1 km. The course is fast and flat, running alongside Penrith Lakes with views of the Lower Blue Mountains and adjacent parkland. The route loops the main lake, crosses an island bridge towards the Regatta Centre, and utilizes roads around Penrith Whitewater Stadium. Its flat terrain is ideal for runners aiming for a personal best, while the shorter distances cater to new runners and families. The venue also has a significant running history; the Western Sydney Marathon has used this area for events ranging from youth races to marathons, drawing both local beginners and national/international competitors.
