[3] Between 1957 and 1973, Wolfshohl took part fifteen times in the World Cyclo-Cross Championships where he won twelve medals.

[4] The first time that he reached the podium in the World championships of cyclo-cross was the bronze medal in 1958 behind the Frenchman André Dufraisse and the Italian Amerigo Severini.

The UCI instructed that the course be made tougher but Wolfshohl was in great form and spent most of the race alone at the front.

In 1968 Wolfshohl had to return his silver medal at the Cyclo-cross World Championships because of a positive doping test.

At that time Liège–Bastogne–Liège and La Flèche Wallonne were run on successive days as "Le Weekend Ardennais."

Wolfshohl came seventh in La Flèche Wallonne and as a result won Le Weekend Ardennais in 1962.

In the World Championships road race of that year, Wolfshohl finished fourth behind Jean Stablinski of France.

Wolfshohl showed himself to be the strongest in the race and kept the leader's jersey to the finish where he won with six minutes advantage over Poulidor.
