"It was a personal best by 45 seconds," Babe said.
"Looking at where she was in terms of her training, we agreed on a predication that she was capable of running [and she surpassed that].
"We could see that if the conditions were right, and a top-class field was competing, that she could do pretty good."
Babe said that two kilometres from the finish line Davies was in eighth, before she powered ahead and pegged one runner back at a time. "That performance was special, it's only early in the season.
"The European season is only just starting [and at this early stage] she's ranked in the top 10 in the world."
He said the Ottawa International was part of a series of races going into the worlds that he and Davies would use to get the 30-year-old runner in the shape she needs to be in.
Meanwhile, three more athletes have been added to the Athletics New Zealand team for the world championships.
Brent Newdick (decathlon), Jake Robertson (10,000m) and Kim Smith (10,000m) were named yesterday by the Athletics New Zealand selectors.
All have reached the Athletics New Zealand B performance standard.
Newdick is currently in Europe preparing for a decathlon in the Czech Republic while Robertson is training in Canada and Smith continues her preparations from her base in Providence, Rhode Island.
They join four previously announced team members: Valerie Adams (shot put), Davies (marathon), Quentin Rew (50km walk) and Nick Willis (1500m).
