Share ‘Walk to Cambodia’ challenges volunteers to cover over 7,000km to raise money for charity Tue, 4 May 2021 The distance from Siem Reap to Sydney, Australia, is 7,252 km. The flight takes more than 13 hours, but if someone could somehow walk the entire distance and traverse the oceans on foot it would amount to around 9,572,640 steps and you’d need to take about 319,000 steps per day to make it in one month. The Walk to Cambodia is an annual fitness challenge where participants are encouraged to collectively walk a distance equal to the distance from Australia to Cambodia. “We do that by tracking our steps every day in April, and along the way we collect fun badges with info about the different landmarks and cities we have walked to in Cambodia,” said Sally Hetherington, the CEO of Human and Hope.
