Sam became the youngest person in history to beat a four-minute mile (about 1.6km) with a time of 3m 58.35s.
“I guess I didn’t really understand that what I was doing was different to other people until things went a bit crazy after I broke the four-minute mile,” he said.
In the past year, running has brought Sam a Nike deal, national records, world records and the chance to compete across the globe – from Los Angeles to Tokyo.
The Year 11 Tauranga Boys’ College student told the Bay of Plenty Times about the very first time he started running somewhat competitively.
“I was 5 years old and in my first three weeks at Pillans Point School in the school running race.”
He said he remembered loving it but also getting beaten by some of the other kids.
In just the past year, running has brought Sam a Nike deal, world records and the chance to compete across the globe – from LA to Tokyo.
“I have always really enjoyed running, and I’m lucky that hasn’t really changed since.”
As a college student, with a couple of years still ahead of him, Sam said it was quite hard managing school and travel.
“It’s mainly because all of the fastest times in the world are run in the opposite hemisphere and in the opposite season.”
Before breaking the four-minute mile, Sam first broke the 15-year-old world best for 3000m in November 2024, then lowered it twice more – running 7m 56.18s in February 2025.
He beat the previous mark, set by former Commonwealth Games runner Richard Potts in 1989, by eight seconds.
A day later, on December 7, he set a new 800m record with a time of 1m 46.81s in the final at the New Zealand Secondary Schools Track and Field Championships.
The teen has running in his genes.
Sam’s grandma Rosemary Wright (nee Stirling) was a champion 400m relay sprinter and 800m Commonwealth Games gold medallist in 1970.

“I remember him running laps of the tent at Ohope Beach when he wasn’t even 2; he just ran around and around and loved it right away.”
Ruthe said in the early days, Sam had a “float to his run”, where runners maintain a fast but relaxed pace during a run, which he said was rare from the start.
“It’s partly because of that we didn’t let him train until he was 13.”
Ruthe said both he and Sam’s mum, Jess, felt fortunate they could help Sam on the path he had chosen.
“It’s something special to be able to understand his sport. He’s just a genuinely enjoyable person to spend time with, and it’s a privilege to help him.”
Ruthe said he didn’t think anyone in the world could do what Sam had done.
“I wouldn’t have believed it if you told me a few years ago that a 16-year-old would be doing what he’s done.
“Getting to see it all unfold up close is a privilege.”
