One of Australia’s steepest residential streets will become a sea of colour, laughter and sweat as the Humpty Dumpty Balmoral Burn 2025 brings thousands together in Mosman for a race that raises vital funds for children’s health.
More Than Just a Race
Set for Sunday, 25 May, the 23rd Humpty Dumpty Balmoral Burn will see families, schools, athletes and even pets tackle the 420-metre Awaba Street climb to raise funds for vital children’s medical equipment.

More than a fun run, the Balmoral Burn is a community event backing better care for sick kids, with over $35 million raised since 2001 for 500+ hospitals nationwide.

While elite runners chase King and Queen of the Hill titles, many others join simply to be part of the day. Events cater to all levels, from family relays and the No Burn Walk to the always-popular Pet and Owner Race.
A Morning Packed With Colour and Character
This year’s program features over 20 races from 8:10 a.m. to midday, including the crowd-favourite Run Baby Run, where participants tackle the hill in inflatable baby suits to honour premature and sick newborns.

Other favourites include the colour-filled Celebration Run and Corporate Relays, where local teams compete in friendly rivalry. Adding to the energy are appearances from event founder Phil Kearns AM, Nine’s Amber Sherlock, and Mosman distance runner Ed Goddard.
Giving That Goes the Distance
The Balmoral Burn is all about impact, with fundraising rewards like race entries, merchandise, lunches, and even a visit to the Humpty Dumpty Foundation. Those who raise $10,000 or more earn a personal thank you from Phil Kearns.

Every dollar helps place urgently needed equipment into hospitals, from portable oxygen machines to neonatal monitors, changing the lives of sick children and their families across Australia.
