Early career

Zülle (centre) during the amateur race at the 1990 UCI Road World Championships

Zülle was born and brought up in Wil in the canton of St. Gallen, son of a Swiss father, Walter Zülle and Wilhelmine, from Brabant, Netherlands. As a child he wanted to be a skier but at 18 he was injured in an accident. He began cycling in the Netherlands for rehabilitation before giving up because it was too windy.^[1]

His father, having bought cycling equipment, persuaded him to give cycling another go when they returned to Switzerland. After several years as a successful amateur, Zülle turned professional in 1991. He approached the former sporting director of the Swiss team, Helvetia, Paul Köchli, but Köchli signed Laurent Dufaux instead.^[1]

Zülle then approached Manolo Saiz, but was rebuffed because, among reasons, he did not contract riders who wore earrings. Eventually, Saiz softened and Zülle rode for ONCE as a stagaire or apprentice in the Volta a Catalunya. He attacked frequently and finished third. Saiz relented and Zülle signed his first professional contract in September 1991.^[2] He remained with ONCE until 1997.^[3] Most of its riders were Spanish. Zülle spoke only Swiss-German when he joined but at the end of the Vuelta a España he answered journalists in Spanish.^[4]

Festina affair

In 1998, Zülle joined Festina. The team was banned from the 1998 Tour de France amid doping allegations which later became known as the Festina affair. Five Festina riders including Zülle admitted taking EPO.^[5] Zülle said he took it to satisfy his sponsors. He also said he was deprived of his spectacles during the police interview.^[6] On 28 November 1998, Zülle's haematocrit was found to be 52.3%, 2.3% over the limit.

1999–2004

His career coincided with that of Miguel Indurain, five-times Tour de France winner. Zülle was second in the Tour in 1999. He also won the Vuelta a España and Tour de Suisse, and stages in the Giro d'Italia. Following financial problems for his employer, Team Coast, Zülle transferred to Phonak on 27 March 2003 in a rare mid-season switch.^[7]

Zülle retired in 2004, and held a party for his fans in Wil in October that year.^[8]
