Tackle Sydney’s Steepest Hill for a Great Cause: The 25th Anniversary Balmoral Burn Pet & Owner Race
Registrations are officially open for a significant milestone in the Sydney event calendar—the Humpty Dumpty Balmoral Burn.
Returning on Sunday 24 May 2026 to Awaba Street, Mosman, this year marks the 25th anniversary of the iconic charity challenge.
Bringing together thousands of participants to tackle Mosman’s infamous 420-metre incline, the Balmoral Burn is more than just a test of endurance. Every step taken on that 1:4 grade hill helps the Humpty Dumpty Foundation provide essential, and often lifesaving, medical equipment to more than 520 hospitals and health services across Australia.
A Milestone Celebration for Pet Owners
While the event hosts over 20 race categories, for the Australian Dog Lover community, the highlight remains the Pet & Owner race. This dedicated category offers a unique opportunity for Sydney dog owners to help "pets with paws" do their bit for a vital cause.
Whether you have a seasoned canine runner or a pup happy to enjoy the atmosphere at a slower pace, the sight of hundreds of dogs and their owners conquering Sydney's steepest street together is an annual highlight of the program.

The Humpty Dumpty Balmoral Burn was founded in 2001 by Wallabies great and Humpty Ambassador Phil Kearns AM. In the 25 years since, the event has raised an incredible $36.5 million. These funds have a direct, tangible impact; the Humpty Dumpty Foundation is the largest charitable supplier of children’s medical equipment in Australia. In 2025 alone, two-thirds of the hospitals supported were in rural or remote communities, ensuring every Australian child has access to quality healthcare regardless of their location.
Event Essentials
The atmosphere at Balmoral is unmissable, featuring delicious food, live entertainment, and activations for the whole family (and their dogs!).
