The 400m win was more straight forward and came just a month after another major victory over that distance in the Wairarapa College colours at the national secondary schools track and field championships in Timaru.
Going into the long jump, however, Starzynski was not anticipating anything special as he had done no training for the event. But he took away the gold medal with a best leap of 5.93m, which was 70cm further than he had managed before.
"I was really stoked with that, I had no idea how I would go. It was just a case of giving it everything and hopefully things would work out."
There is a possibility now the long jump will become a more regular part of the Starzynski training regime as the youngster is keen to develop his skills in that discipline.
It is sure to become part of conversations with his Wellington-based coach, former Fijian Olympian Autiko Daunakamakama, who was a 400m specialist, both on the flat and over hurdles. Daunakamakama sets out the programmes for Starzynski to follow and Mikael's father, Andrew, is invariably on hand to ensure his son does what is required of him.
The presentation of the Willis scholarship to Starzynski was made by 2016 Colgate Games ambassador and New Zealand champion 1500m runner Julian Matthews who said it was grounding to see kids competing at such an intense level.
"I was impressed by the amazing talent and dedication and I'm sure there were some future stars in the making."
The Colgate Games are in effect New Zealand's national junior athletics championships for children aged 7 to 14, and have been running for 38 years. This year more than 2000 young athletes from more than 100 athletics clubs across the country competed at the two events in Palmerston North and Nelson.
