"I didn't get a bike until I was 60," he said.
In 1994 Mr Boyden began organising the Manawatu Gorge Track and Tunnel event, which has raised $300,000 for the Arohanui Hospice in Palmerston North and other charities.
Mr Boyden said he never thought the Track and Tunnel walk would become such a huge event and admits the logistics of both fundraisers are "enormous".
So why does Mr Boyden continue?
"It's a challenge and a bit of pride too," he said. "I don't want to see either event fall to bits," he said.
Mr Boydon says he'll continue to organise both events for as long as he can. But while he believes it is the worthy causes which attract participants and wonderful sponsors to both events, he has a much more personal reason for wanting to carry on. "When our son Jason was battling cancer he was flown from Taupo to Palmerston North by the rescue helicopter service and spent time in Arohanui Hospice," he said. "We'd raised money for syringe drivers for the hospice, but I didn't know what they were until Jason was using them."
Jason passed away last year and while it would have been easy to hand over the organisation to someone else, Mr Boyden said the Coast to Coast and Track and Tunnel walk helped take his mind off what his son was going through.
"It's the one sad thing about this award, that Jason isn't here to share it with us."
