Entries for IRONMAN UK 2021 will open to all athletes this Thursday (July 16) at 1pm.
The gruelling triathlon - made up of a 2.4 mile swim, a 112 mile bike ride, followed by a marathon - will take place in and around Bolton on July 4, 2021.
The borough has proudly hosted the IRONMAN event since 2009. Unfortunately, this year's event could not take place due to the coronavirus pandemic.
Leader of Bolton Council, Cllr David Greenhalgh, said: "Ironman is a huge test of endurance and one of the ultimate challenges anyone can take on.
"Our borough has been hosting this brilliant event for many years now, and we are looking forward to welcoming all our athletes and spectators.
"We hope to see everyone who was going to take part this year, and we will be working with IRONMAN to make next year's events the best yet."
IRONMAN UK Race Director, Sam Brawn, added: "We have been working hard to make sure that next year's race is even bigger and better.
"We cannot wait to once again experience the thrill of racing and to welcome all the athletes and supporters to the 2021 race!"
