He said the presence of Olympians, including hammer thrower Lauren Bruce, high jumper Hamish Kerr, long-distance runner Sam Tanner and others, was a huge factor for large crowd numbers.
“To see that crowd around by the high jump was just terrific – the atmosphere and the look on their faces when they had an Olympic champion jumping was one of the highlights for me,” McNab said.
“We had the largest numbers for some years for an athletics meeting in Whanganui.”
Paris Olympics gold medallist Kerr won the high jump with a 2.24m leap.
McNab said his presence and the atmosphere around the event resulted in the other jumpers breaking their personal bests.
Cooks Gardens is renowned as “the home of the mile” for Sir Peter Snell’s world record of 3m 54.4s, set there in 1962.
This year’s men’s open mile was won by Olympian Sam Tanner, clocking in at 3m 55.75s – his third consecutive win in the event.
In second place was Australian Jack Bruce, just falling short by 1.15s with 3m 56.90s.
McNab said the open men’s mile race “completely delivered”, with 45 entries.
“There is always a good atmosphere, particularly because of its reputation for the mile. It has been years since 45 have entered an event like the mile - it speaks for itself.
“Cooks Gardens really is the home of the mile.”
The stadium previously had 77 sub-four-minute mile times – it has increased to 79 with Tanner and Bruce’s performances.
