THE wait is nearly over for the highly anticipated return of Ironman.

The triathlon will return to Dorset this Sunday (September 17) and will see athletes from across the world swimming, cycling, and running in an epic physical challenge.

The annual triathlon race, thought to be the ultimate one-day test of endurance, is made up of three parts, a 1.2-mile swim, a 56-mile cycle and a 13.1-mile run.

Ironman 70.3 Weymouth race director Lewis Peacock, said: “We can’t wait to welcome back thousands of athletes to the Jurassic Coast.

"The support of the locals in this beautiful part of the world makes for an extra special race day atmosphere. Being able to race in such a popular UK holiday destination is a privilege, and one we’re sure any first timers to the race will love.”

Former female winner of Ironman 70.3, Natalie Lawrence is returning to Weymouth where she will race to reclaim her crown.

Niall McGloin will also be taking part in the triathlon in memory of his Dad, Ray McGloin, who sadly passed away in August last year.

Ray founded the triathlon club Tri-Rivington UK based in Bolton and was a fantastic ambassador for the sport of triathlon with his emphasis on community spirit, a balanced lifestyle, and support for members and athletes both physical and mental health.

Tri-Rivington UK has produced countless IRONMAN finishers over the years and will continue to do so into the future thanks to the solid foundations Ray built and the continuing work of all the fantastic members at the club.
