At the age of 98, Whangārei's Colin Thorne celebrated finishing his 100th parkrun - eight years after giving up marathons.
Thorne took up running late in life, yet still managed to complete 50 marathons from the age of 64, and lost track of how many half-marathons.
"If I'd been a bit younger when I started, I might've done a few more," he told the Advocate.
He continued with parkruns after running his last Rotorua Marathon in 2014.
Despite arthritis and age-related aches and pains that mean his speed is down to a walk and he uses a stick to help with his balance, he said he wanted to keep doing the 5km parkruns as long as possible.
