- Hiromu Inada, from Japan, was first awarded the Guinness World Record in 2018
- He is showing no signs of slowing down and continues gruelling training regime
- Inada only began swimming, running and cycling at age 69 after retirement
World's oldest ironman has said that he will continue competing into his nineties.
Hiromu Inada, 87, was first awarded the Guinness World Record for the oldest person to complete in the world championship ironman in 2018.
But despite the accolade he is showing no signs of slowing down as he continues his gruelling training schedule at a sports facility in Chiba, east of Tokyo.
In 2018, at the age of 85 years and 328 days, Inada went to Kailua-Kona in Hawaii and set a new mark for the oldest person to complete in the competition - a feat beyond most people decades younger than him.
The cancellation of this October's Ironman, due to the coronavirus pandemic, has not dulled his ambition.
He said: 'My goal is next year's world championship in Hawaii.
'I will absolutely participate in it, and I absolutely want to break the world record of completing the race at the oldest age again. This is my current and biggest goal.'
An Ironman race is widely considered one of the toughest endurance events in sport as it requires athletes to swim 3.86 km, cycle 180.25 km and run a full 42.19 km marathon.
Inada only took up the sport in retirement after working for public broadcaster NHK.
He began swimming, running and cycling at age 69 and completed in his first triathlon a year later.
Inada's wife died soon afterwards and Ironman competitions then became something of an obsession for him.
In 2015, at age 82, he took part in the Hawaii Ironman, bidding to become the oldest finisher on record, but he fell just short: his time was five seconds too slow to be officially registered.
Inspired by support from the Hawaiian public, Inada returned and completed the race in a qualifying time, earning his Guinness World Records certificate.
'Until then, I had thought I would give up if I felt I had enough of it,' Inada said.
'But since then, I have in my mind that I absolutely cannot give up, and I absolutely must complete (Ironman races), otherwise I feel sorry for those who support me.'
Inada continues to train every day, waking up at 4.30am and hitting the swimming pool by 6am.
Inada sees the extended lead-in to his next trip to Hawaii as on opportunity to rest a sore knee and tweak his preparation technique.
'I hope I can try new things to build my fitness,' he said.
'I hope I can adjust my physical peak to the postponed race. So, I would rather think it was good that it was delayed.'
