More than 100 beautiful women from across the globe will vie for the Miss World crown in the Chinese resort of Sanya on Saturday in a pageant sure to deliver sex appeal and glamour.
William Hill listed Birkedal's odds of winning at 6/5 late Friday, followed by Alexandria Mills of the United States and Yara Santiago of Puerto Rico, both at 7/1. Serbia's Milica Jelic is fourth in the running.
"I really can’t believe I’ve been chosen best model out of so many wonderful girls here," said Birkedal.
"It’s a great honour for me and, of course, I’m delighted to be in the top 25. Now I can look forward to the final."
After a month-long tour of China, from visiting the striking Bird's Nest stadium in Beijing to shopping in Shanghai, the 115 contestants have now invaded Hainan island's pristine beaches for the main event.
The competition, which was first held in 1951 and is being staged in Sanya for the fifth time in eight years, annually rakes in a global television audience of about a billion viewers.
"Miss World has a special relationship with Sanya and there is no better place to begin our 60th year celebrations," the pageant's co-chairwoman Julia Morley said on the official website.
There are currently no plans for the event to be broadcast live to China's huge homegrown audience of 1.3 billion people.
The glittering final competition, to be judged by seven former Miss Worlds including 1953 winner Denise Perrier Lanfranchi of France, will see the reigning glamour queen, Kaiane Aldorino of Gibraltar, relinquish her throne.
The event rivals the Miss Universe pageant owned by US tycoon Donald Trump. This year's winner of that title, awarded in August, was Mexico's Jimena Navarrete.
The Miss World competition emphasises the importance of charity work. Miss 'Beauty with a Purpose' is one of several contestants who have earned "fast-track" spots in the finals by winning mini-titles.
Along with "Top Model" Birkedal, Santiago booked her place with the Beach Beauty title, and Ireland's violin-playing Emma Waldron won the talent contest.
Lori Moore of Northern Ireland, a 20-year-old hockey and netball enthusiast, also secured her spot by taking the Sportswoman crown.
In 1951, Sweden's Kiki Hakansson became the first Miss World. Oscar-winning American actress Halle Berry was a finalist in 1986.
Venezuela and India have produced the most Miss Worlds, with five titleholders each. Bollywood star Aishwarya Rai took the crown in 1994.
In 2002, the pageant was moved from Nigeria to Britain after more than 200 people died in clashes sparked when a newspaper suggested the Muslim prophet Mohammed would have chosen a wife from among the contestants had he been alive.
