Ironman 70.3 Western Sydney returns to the International Regatta Centre in Penrith. The course is nestled at the base of the Blue Mountains and uses the protected Penrith Lakes, located at the International Regatta Centre, for the swim. The bike course includes breath-taking views of the Blue Mountains. The flat run course takes in Penrith’s Nepean River along the scenic Great River Walk before runners return to the iconic Sydney International Regatta Centre venue where supporters have plenty of places to cheer on athletes and to celebrate as they run down the finish chute. It’s also super easy for you to race, stay and play in Sydney. With Sydney CBD check-in, you can check-in right in central Sydney on Friday, they’ll transfer your bike to transition, and there are athlete buses from the Central Business District to the event village on Saturday and race day. They have so many options to make your race journey the best yet!
