All three women were a bundle of excitement as Roe arrived at Mahurangi River Winery.
"I just wanted to cry," Barbara said.
She is the same age as Roe, and remembers when the marathon legend was at her prime.
"She wasn't just doing it by a few seconds, she was smashing records."
Her daughters, however, were "in nappies" at the time, but they knew the famous name and were equally inspired by her.
Victoria said the main piece of advice they got from Roe was to talk to yourself and use positive visualisation.
"She was saying you can't control the weather, you can't control the temperature, and she said she used to say to herself 'I'm feeling refreshed," regardless of what the conditions were."
On the Great Wall run, Victoria will also battle her fear of heights, after facing it gradually over the past year. "I've been up Mt Manaia three times."
Lucie is the only one of the three to have been to China before, on her OE in 2010.
