How can a simple walk in the park turn into thousands of dollars for cancer care at leading non-profit Chris O'Brien Lifehouse? By adding up:

• 28 kilometres walking Royal National Park's Coast Track
• 8 hours of effort
• 35,000 steps (you can do that, can't you?)
• Then equate every step to a mere 2 cents to reach your $800 target ($3200 in your team of four).

We're proud to partner with Walk with Lifehouse, the inaugural coast trek challenge benefitting Chris O'Brien Lifehouse. We're working closely with Lifehouse on all things walk-related, to ensure 100 walkers have the best route, most thorough preparation and safest experience. Ian and I will be walking, along with our team of professional hiking guides, to support and encourage you on the track. We've got your back, so that Lifehouse can do what they do best: world-class patient focused cancer care near Royal Prince Alfred Hospital.

It's also your chance to join Gail O'Brien, wife of the late Professor Chris O’Brien (AO), who'll be walking on the day. Gail's personal story of how she found meaning in her life after the devastation of her husband's illness is inspiring.

The walk will start at Otford lookout, down through Palm Jungle, and pausing at Garie Beach for morning tea. Then we'll re-fuel at Wattamolla with lunch and re-energised, set off for Bundeena, going via Wedding Cake Rock. It's definitely going to be challenging – we usually suggest this 28km track as a more relaxed two day walk – but that's the whole point. Your sense of achievement and of making a difference will skyrocket with the effort. I recommend bringing a camera as the views (and camaraderie) will keep you going.

Join the Walk with Lifehouse challenge (and if you're quick, you'll save with Early Bird Registration before 1 August)! We look forward to seeing you out on the track.
