And it isn't just her and Nigel - plenty of supporters are following her progress; since setting off on September 1 she had raised $600, adding to the $11,000 raised before she set off.

Ms Ladd was anxious to raise awareness of MS as she went. It was an illness that predominantly afflicted women aged 25 to 30, of Caucasian descent and further from rather than closer to the equator. It was prevalent in the UK, Scandinavia, Australia and New Zealand, she said, for reasons that no one could explain.
And while she had been covering significantly more than the 20km per day that she was targeting, she was taking the time to reacquaint herself with the beauty of her homeland.
"I had forgotten how beautiful this place is," she said.
"We are so lucky to grow up in a country like this. Now I've got some beautiful hills to look forward to. They are much bigger than your average Australian hills."

She was amusing herself on the trail with songs retrieved from her childhood.
