When asked about the secret to his longevity and success in the sport, Gade said, "I have big motivation, big determination to do well against my opponents."

"This is a tough sport, a tough category, and I always have the motivation to practice hard every day. I wouldn't be here if I hadn't been working real hard, every day, for so many years," he added.

His trademarks include a shot to the back of the court while drawing his opponent towards the net, and reverse forehand shots where the shuttlecock meets the racket at sharp angles.

Experts praise his mental composure, tactical ability and team spirit as much as they admire his deft footwork, drop shots and fast attacks.

"Peter has been a wonderful ambassador for Danish sports and particularly badminton for so many years," said Jesper Frigast Larsen, Denmark's Head of Mission at the 2012 Olympics.

"This is his last Olympic games as an athlete, but I have a feeling Peter will continue in this sport as a trainer and coach, and hopefully be on the Olympic team in future in another capacity," he said to Xinhua.

Gade himself told Danish media late last year that coaching could be his new calling after the Olympics, and that he is interested in both national-level coaching and in developing new badminton talent.

Whatever he does, the glorious memories of participating in the Olympics in the company of great athletes will remain with him.

"The Olympics are always very special ... I am with the rest of the Danish team and it is always special to be part of this team. I don't think that feeling is going to change. I will enjoy it and take what I can from this Olympics," Gade said.
