The weight on Colin Thorne's shoulders must feel immense - not that he would be too phased.
The Whangarei nonagenarian has made it across the finish line of his 100th half marathon in one piece, thus successfully ticking off another box to hang yet another weighty winners medal around his neck.
The 91-year-old ran the Air New Zealand Queenstown International Marathon's 21km race on Saturday, and completed it in a time of 3:16:52.
"I suppose there's plenty done more, but I don't know if there's many at my age," he said.
Enduring a mainly flat course, with some undulations to keep it interesting, and a unique mix of running terrain including smooth, hard-packed trails and road, Thorne said he was aware of the dangers on the offroad parts of the course heading into the event.
