"Rather than do that [wait at the finish line] now I'm out there in the course and he is well and truly finished so I don't have to worry about him," she says, relishing the role reversal of him waiting to greet him at the finish line.
"I'm about surviving and he's like competitive," says Wendy who flirts with the five-hour mark these days, content to take in the scenery and not feeling the urge to be wired for sound.
But the convivial Napier couple's marathon marriage will reach a milestone when they compete in the Air New Zealand Hawke's Bay International Marathon the following Saturday.
On completing the marathon here, the Beverlys will mark their 45th wedding anniversary with family members, including Wendy's brother, Peter Raisher, of the Bay, as a couple who have simply run 42.2km rather than gingerly building from shorter distances.
"We're just self-trained and whatever," she says of their amazing journey to keep up with the big dogs rather than lounging on the balcony.
"We've been very slack in our training because it's been a little while since we've done a run," says Wendy although walking and biking is part of their repertoire while they renovated their Napier home for selling.
It seems a healthy dose of sense of humour also has been crucial in keeping them keeping on to ensure the countless micro threads of matrimony remain intact.
"That's why I married her. I grabbed her because I wanted a cheap farmer's worker, didn't I," says David when asked about how Wendy feels running marathons has kept the matrimonial flame burning in the game of life.
"We've lived our lives together and, like everybody else, we've had our ups and our downs but we'll be together for 45 years in a few days," he says.
The former Waikato dairy farmers sold up and moved in 2001 to the Gold Coast where David drove public buses before returning in 2012 to settle in Opunaki but found the ideal climate in Hawke's Bay where they resettled in Napier for two years.
"We had to find somewhere warmer to live so Hawke's Bay would be our ideal place to live."
They sold their Napier home in last November and are now travelling around the country in their motor home but return to the Bay whenever they can.
The couple have three children - Diana, of Palmerston North, Christine, of Cambridge, and Annemarie, of Charlotte, in the United States - eight grandchildren and a great-grandchild.
That gives the great grandparents an excellent excuse to choose a nomadic existence, escaping this part of the world as heat hogs to capture the northern hemisphere summer from July to September.
"As you get older you need the warmth, don't you?'
If it makes you sigh to think anyone can do back-to-back marathons then be prepared to shake your head in disbelief that they have racked up a rash of four marathons in five weeks.
The first one took in Europe before taking in the US.
In the San Francisco coast leg they met Hollywood star Tom Hanks, of the Forrest Gump fame, in 2004.
"We didn't get a prize from him but we got a photo when we completed our run," she says after ticking off Paris, conquering London before jetting New York then on to Big Sur in San Diego.
Recalls David: "He just asked, 'How the heck can you do that?' He was really great. I hear he's still running [as Forrest Gump]."
That was the first time the couple embarked on an around-the-world package tour over five weeks.
They always planned their trips but these days, as pensioners, it requires a little more forethought to embark on journeys.
David used to play night tennis with neighbours in a four-person team in Cambridge when one day a yawning poster on a 25th Rotorua Fletcher Marathon.
"I went home and said to Wendy I'm going to run a marathon next year," he says, making his way to a club in Cambridge where he joined a group of about 10 were training for the marathon.
"I went to my first marathon in 3h 14m 53s later I ended up in a recovery tent for three-quarters of an hour," he says with a laugh.
He hovered around that running time until three years ago and over the entire duration he's only had one year off because it took him 18 months to recover.
"The only bad injuries I had were stress fractures on both legs when I got to the 10th round of a Rotorua Marathon."
As a youngster he loved running around but there's no pedigree runner in his lineage.
"When we were growing up there were always community things so no television. We just had the radio so we had to make our own fun," he says.
David, his brother and a mate from the neighbourhood used to make their own bow and arrows to go hunting and trapping eels in the countryside.
He echoes the sentiments of Wendy that taking in panoramic views of what they already think what the world is.
"Our second daughter, Christine, will be running with us in Hawke's Bay and our youngest would probably do it with us but she can't come back from Charlotte just now."
David intends to clock up another half a dozen marathons each year to make the 150 mark.
The Bay marathon also has a New Zealand Sotheby's International Realty Half Marathon, a 10km run and a children's grade.
