On the podium he looked skywards, blew hard, doubtless thinking of all the months of work which went into this success.
Then there were his parents, Jason and Sandra, sitting high in the Chris Hoy velodrome, and his cousin Emma looking on.
He sang the national anthem, sandwiched between "two of my best mates". Dawkins gave him a playful tug on the shoulder before arms were raised aloft.
"It all catches up with you, how much work you put in and it's all worth it when you're on top of the podium."
These are salad days for the New Zealand sprint programme, and the key is their ages. They are only starting to suggest what they could be capable of.
