Upon reflection, for a man with an ever-growing trophy cabinet, Brown says this honour ranks "right up there".
"I'm extremely happy to receive the award, it's pretty unexpected you know, all you're trying to do everyday is swim, bike and run to your best ability and you never think of getting this award so quite an honour," Brown told Radio Sport.
Brown has also been commended for his work with cystic fibrosis.
"It's nice to support those charities that have been alongside Ironman for many, many years.
"It's [triathlon] an individual sport, you're thinking about yourself a lot of the time but there's a lot of other people and athletes and organisations that can use valuable help and money."

Brown hopes he has followed in the footsteps of his heroes, Rick Wells and Erin Baker, who found success in the 80s and 90s.
"I'm just trying to help the sport of triathlon and get it back on top in a country where we're thriving in swim, bike and running every year."
44-year-old Brown still hopes to win a few more Ironman titles after recording his fastest New Zealand Ironman time at this year's event.
"It gets harder and harder with age, you know, 44, 45 in March so it's going to get tougher and tougher.
"Hopefully there's something left still in the tank but I know at some point retirement will be round the corner so I'll hold off as long as I can."
