IRONMAN Western Sydney
IRONMAN 70.3 Western Sydney is on 2 May 2027 at Penrith, with the swim in a still-water rowing lake, a flat and fast 90 km bike, and a flat 21.1 km run.
A purpose-built regatta lake is about as controlled as an open-water swim gets: no surf, no current, no tide, and a course you can sight without lifting your head much. If sea swimming is what holds you back, this is the race to enter.
Early May is late autumn here, so the heat that makes Western Sydney uncomfortable in summer is gone and the water is cool enough for a wetsuit.
Penrith is at the foot of the Blue Mountains, about an hour west of central Sydney, and the train line runs there directly. That makes it reachable without a hire car, which is worth something if you are flying in with a bike box already.
