Miller has run 10.38s on the Tauranga track and holds the New Zealand record of 10.32s.
Later in the 200m French caused an upset by running 21.20s to just beat Millar in 21.26s. Goldie again ran well for third place in 21.72s, with club mate Mathew Connolly fourth in 22.11s. Another young Tauranga Rambler Ethan Holman showed good form to win his 200m heat in 23.72s.
Rising women's sprinting star from Tauranga Abby Goldie won her 100m heat in 12.04. Tauranga's Brooke Somerfield was third in 12.36.
Julian Oakley won the 3000m men's open race in 8m 38.42s ahead of Jonathan Jackson 8m 39.75s and Tauranga's Ben Ruthe 8m 42.71s. Oakley is home from his US base where in June he ran 3m 58.89s to break the magic four-minute mile in Massachusetts, beating current 1500m Olympic silver medallist Leo Manzano.
Meeting organiser Malcolm Taylor says the races showcased how good the track is for fast times.
"The heat warms the track up and gives the runners a bounce," he said. "It is brilliant. It does have issues with wear but on a day like (Thursday) with extreme heat that is when Mondo tracks are at their best," Taylor said.
"I think it will still be several years before the track is replaced. We will continue to have meetings on it until it is replaced. We had some very talented athletes here and they were running fast."
