They take their sport dead seriously at Collegiate - it is part of the various codes mandatory curriculum that athletes enter local events on weekends, such as the fun run, with such support bringing a healthy and gratefully received boost for entry numbers.
Unsworth's name has come across my desk a few times in the past three years - a handy batsman for the school's First XI who played age grade for Whanganui, and a strong winger who made the tournament team at the Hurricanes Regional competition from the Whanganui Under 16s, thereby earning the right to take part in that Super Rugby franchise's youth development camp.
In the running stakes, he is a contemporary of schoolmates like international cross country representatives Christian Conder and Jane Lennox, former school star Geordie Beamish, and the likewise world-travelling Harry Symes.
Therefore, it's safe to say 'holding back' would not be two words commonly found in the Unsworth vocabulary.
However, on May 22 when 10-year-old St George pupil Oliver Jones came puffing up beside him on the Dublin St Bridge and proceeded to "hit the wall" as it's known in running - adrenaline drains away and the mind begins to tell the body it can't keep going - Unsworth chose to abandon personal goals and guide the young lad home.
Unsworth stayed with Jones, encouraging him, drafting alongside him, and creating quite the inspirational sight as the pair approached the Kowhai Park finish line together.
Mum Lesley Jones describes the moment better than I could.
"Oliver catches up to this Collegiate (Giant) and says 'will you run with me and help me through to the finish?'
"The Collegiate boy, steps up to the request and says 'Keep going, you can do it. Don't give up, come on, you can beat me'.
"He puts his own race on hold to support this small guy who is giving his all, putting others before self."
It was fantastic to have a home-grown version of a similar story that went viral a few years ago.
In the small town of Charlevoix, Michigan, competitive 19-year-old US Marine Myles Kerr had entered the town's annual race with his local unit when distressed 9-year-old Boden Fuchs came to his side.
"Sir, will you please run with me?" Fuchs asked, struggling badly after losing the group he had started with in the 5km event.
Everyone knows if you give a Marine a mission, he sees that mission through to the end.
Kerr stayed with the boy for the remainder of the race, letting him finish ahead of him in around 34 minutes and well behind the rest of his unit.
If you look above, you cannot help but notice the symmetry between the two photographs - the picture of Kerr went global with over 200,000 'likes' on Facebook.
"After that he came up to me, hugged me and said thanks. It was cool," Unsworth modestly understated this week.
Strong athletes setting aside desire for personal success in order to encourage a young fellow to achieve something that they felt was beyond them.
We have our new definition of winning.
