The 15th Ironman WA is underway in Busselton with triathletes from around the globe swimming 3.8 kilometres, cycling 180km and running 42.2km.
Terenzo Bozzone claimed his third title at the event crossing the finish line in 7 hours and 56 minutes, Caroline Mizumoto was the first female to finish in 8 hours and 49 minutes.
Athletes were given 17 hours to complete the course, which meant anyone who had not crossed the finish line by midnight would be disqualified.
This year’s event saw duo Kevin Fergusson and Sid James team up to bring their own special brand of mateship, loyalty and devotion to Ironman WA.
Jame’s dream to race Ironman was shattered 25 years ago when he knocked from his bike during a training ride near his home at Victor Harbor, south of Adelaide, leaving him quadriplegic.
Fergusson, who has finished more than 30 Ironman races, including five world championships, wore a harness and towed an inflatable kayak containing James on the 3.8 kilometre swim leg.
He towed Sid for 180 kilometres in a trolley attached to his bike and on the marathon he pushed his mate in a specially designed wheelchair 42.2 kilometres to the finish line on the Busselton foreshore.
