The 2012 Altra Centennial Park Ultra 50km and 100km will be held in Sydney’s leafy Eastern Suburbs on Sunday, 30 September, 2012. Featuring a flat, scenic, tree-lined course, this run is the only ultramarathon right in the heart of Sydney.  Last year's inaugural event sold out and this one is expected to also, so don't delay sending in your registration.

The course is a 3.54 km loop around inside of the iconic park. The surface is a gentle mixture of gravel and packed dirt. This is an officially measured, IAU Silver label event. It is one of only two Australian Selection Races for the IAU World 50km Trophy.

Electronic timing, kitchen facilities, refreshments, competitor bags, and lots of fabulous prizes from our sponsors will be provided.

There will also be thousands of dollars in prize money, plus heaps of spot prizes.

The 100km event starts at 0600; the 50km starts at 0700. Both events will conclude at 1800.
