The crowning achievement of his career was winning the Men's Singles at the 1997 IBF World Championships in Glasgow, Scotland.

It was the first time a Dane and a non- Asian player captured that title since Flemming Delfs won at the first-ever IBF World Championships held in Sweden in 1977.

This is not only due to his playing style which featured speedy footwork and powerful jump-smashes (typically a hallmark of Chinese badminton players), but also because of his spiritual interests.

Rasmussen suffered a career ending foot injury on 25 September 2004, during the Men's Singles Final of the 2004 U.S. Open (badminton).

Denmark and Indonesia were tied 2-2, and Peter Rasmussen vs Simon Santoso would decide who advanced to the finals against China.

Peter claims that the reason why he was so successful on the badminton court was because of his studies of Bushido, an ancient Japanese philosophy and his mentor, Miyamoto Musashi, a great samurai.

At age 35, Musashi sheathed his sword to become a mentor, an artist and finally a writer, who penned one of Japan’s most influential pieces of literature – “The Book of the Five Rings.” Rasmussen had to face the fact of losing before he can entertain the thought of winning.

Denmark took the first two Men's Doubles matches, but Peter Gade crumpled under the pressure of Indo first singles player Sony Dwi Kuncoro.

Kenneth Jonassen followed suit by losing to future Olympic Gold and World Champion Taufik Hidayat.

He beat the youngster from Indonesia, Simon Santoso in front of 12,000 screaming Indonesian fans in straight sets, 15-3, 15-12.

Apart from all the tournament victories Peter has accomplished, he and finalist of the IBF World Championships in 1997, Sun Jun hold the longest game record at 124 minutes.
