Tindall has been running 60 kilometres a day – and is around a third of the way through his ultra-marathon from Warragul in Victoria to the Sunshine Coast in Queensland – since starting 13 days ago.

He will finish his 35-day run on October 27.

Tindall and his support crew will be at Subway Dubbo at the Riverdale Shopping Centre from late morning on Friday.

Organisers have encouraged Dubbo locals to support Billy and his crew by donating online and cheering them on as they arrive in Dubbo.

Tindall will arrive at the Sunshine Coast for the 13th annual “Walk for Daniel” in time to kick off the Foundation’s National Day of Action on Child Safety – “Day for Daniel”.

Billy said he is doing Ultra Marathon for Daniel because “as a father, child safety is something which I feel very passionate about.

“I believe all children should be safe and feel safe, and the work the Daniel Morcombe Foundation is doing, is helping to make that possible.

Bruce Morcombe said: "A run of this magnitude is hard to comprehend. We wish Billy and his support crew the very best of luck. Protecting children is everyone's business. Get behind this bloke and support him as he will make a difference to keeping kids safe."
