It was a bitter-sweet end to the race for the Te Awamutu Athletic Club member who got a sympathetic hug from Hawke's Bay teenage runner Shannon Gearey after the latter had set a scorching 400m pace-setting time for the middle-distance pack under the Canterbury University banner before pulling out to watch the finish.
For someone who had played bridesmaid five times here to Petty, a Cantabrian who last year claimed her eighth crown before revealing plans to join the stable of American coach Danny Mackey in Seattle, Camp dug deep in the second lap but no cigar.
"It was my last opportunity to get the [standard games] time so it's disappointing but, you know, it's how it goes sometimes," she said.
Having run 2:02 in 2016, Camp felt it was do-able but she would have to wait to make her Commonwealth games debut as an individual athlete.
"I knew it would have been within my reach but difficult especially by myself but I'm happy," said the Hamiltonian who has moved to Christchurch to work with Petty's former coach, Maria Hassan.
No doubt, she felt the games-qualifying time would have been more attainable because Petty had pushed her through fast times before.
"Yeah we've had a good battle, Angie and me, over the years and I'm sure it would have been the same if she was here again but, yeah, I've finally got the title she's had for eight years so I'm pretty happy," she said, revealing she had beaten Petty twice in her career.
The 2014 Glasgow Commonwealth Games 4x 400m relay team reserve said she would take a lot of confidence from yesterday's run despite her season's plan going awry.
Camp, who thanked the classic organisers , is now turning her attention to the world championship in October.
"Every year I love coming here because it's a great event and it always has good weather and I run well."
