"He was limping and favouring it that night, but it may have been a part pull and part spasm injury. He's hopeful of getting a race in late in the tour. He decided to go anyway because he'd already paid his fares."
O'Leary collapsed at the end of his 800m at the North Islands and was later diagnosed as dehydrated.
"We travelled by bus and it was a long eight-hour journey. Obviously Oliver had not drunk enough fluids. It took him a good 30 minutes to recover after the 800m and we pulled him out of the rest of the day's competition. After getting a medical certificate the next day, he ran in the relay and was back to his bubbly self and he looked pretty good," McNab said.
"His mission in California is to finally break Josh van Dalen's Collegiate junior 800 metre record. Josh's record is 1.59.80 and Oliver has run 1.59.90, so he's close."
Van Dalen is the brother of twins Lucy (Olympian) and Holly van Dalen.
The Richard Drabczynski-coached Dryden has been carrying a relatively minor shoulder injury, so sensibly didn't go to the North Islands. Conder, coached by his father Rob, also missed the North Islands. He is already at peak fitness.
Lennox ran a solid steeplechase race in Auckland after competing in the 3000m the day before.
"Jane ran well against good fields. Her strength is cross country, so she will get the challenges she's after in Hungary. Grace won her first medal ever at a secondary schools meeting. She finished second in the 400m in Auckland, so she is improving at the right time," McNab said.
"I think all six of them are right where they need to be at this stage of the pathways they are on."
McNab is manager of the New Zealand team in Tahiti and is chef de mission for the Kiwi Secondary Schools team gathering in London for a week before they head to Budapest.
