The Ironman countdown clock has started ticking again in Lichfield and Burntwood.
It is now less than 100 days until the second Staffordshire event.
Competitiors will swim at Chasewater, cycle through parts of Lichfield and finish off with a run at Shugborough on June 12.
Entries sold out in days and competitors from around the globe are expected to compete. Among them are chef Gordon Ramsay and his wife Tanya, who will be raising money for Great Ormond Street Hospital.
Cllr Mark Winnington, Staffordshire County Council’s Cabinet member for economy, environment and transport, said: “The event is a huge opportunity to showcase our wonderful county once again and we are looking forward to welcoming the event back this summer.
“As we get into the 100 day countdown we are confident that in this Olympic year our sporting event will be a fantastic one for the area, for competitors and for local communities.”
It was estimated that the 2015 race boosted the local economy by around £1million.
Kevin Stewart, Managing Director of Ironman UK & Ireland, said this year’s event promised to be another big one.
“Ironman Staffordshire has proved incredibly popular,” he added. “Once again individual places sold out almost immediately and everyone is really is now gearing up to returning to the county once again this year.”
Places are still available for the Ironkids race on June 11, which sees children aged three to 14 taking on runs of between 500m and 2km.
