It has been reported Pippa Middleton may participate in a gruelling Kiwi multisport event next year.
The younger sister of the Duchess of Cambridge said she has set her sights set on doing The Speights Coast to Coast race next February.
In a blog on The Spectator, Middleton said it will be a reason for her to lay off on the food and drink over the Christmas break.
"Next year I am hoping to do the Coast-to-Coast in New Zealand, which is a triathlon (running, cycling and kayaking) from the South Island to Sumner Beach on the Pacific," she said. The race actually runs across the South Island, starting in the Tasman Sea on the West Coast and finishing on Sumner Beach, Christchurch, on the edge of the Pacific Ocean.
"It's in February, so I'd better hold back on the food and drink, starting now. Happy Christmas everyone."
Coast to Coast creator Robin Judkins said he was "very excited" that Middleton had expressed interest in the race.
"We've saved her a place. I think she's got the right background and be right up to the challenge. If she wants to do it we'll make sure she finishes".
He said the race was very popular in England.
"Two years ago we got more entries from the UK then we did from Australia. I'm not surprised she has heard of the best race in the world and wants to take part."
Steve Gurney, a multiple Coast to Coast winner, had offered to train Middleton and race alongside her.
"He's volunteered to run with her during the event and look after her," Judkins said.
"Actually I think there will be a lot of men offering to run with her. She's a beautiful woman."
Judkins joked that many men may actually run behind Middleton, who is famous for her derriere.
"I'm sure some people might get out of the way to let her through."
Middleton has sailed the Atlantic and climbed Mt Blanc, activities she said were good challenges to provide some routine and discipline.
The Coast to Coast race involved 140km of cycling, 36km of running, and 67km of kayaking, and could be either a one-day or two-day event.
Top competitors take just under 11 hours to cover the 243km, while the slowest time ever recorded was 24 hours and 30 minutes.
Each year around 100 international competitors from about 15 countries enter.
