The younger sister of the Dutchess of Cambridge has said she has set her sights on racing in the 243km race from Kumara Beach on the West Coast to Sumner in Christchurch.
Writing on a blog in The Spectator, Middleton said it would be a reason to lay off the Christmas excess in the coming weeks.
“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, somewhat erroneously.
“It’s in February, so I’d better hold back on the food and drink, starting now. Happy Christmas everyone.”
She has previously sailed the Atlantic and climbed Mt Blanc, saying they were good challenges to provide routine and discipline.
The 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.
