Hugo Koblet was the son of Adolf and Héléna Koblet (pronounced Kob-lett), bakers in Zürich.
He lived with his mother, a widow, and with an elder brother.
His brother baked bread and cakes and Hugo was restricted to sweeping the floor and making deliveries by bicycle.
He left the bakery at 17 and worked as a trainee mechanic at the Oerlikon velodrome in the city.
His first race was a 10 km hill-climb, which he won.
That caught the attention of Léo Amberg, a former Tour de France rider who had come second in the Tour of Switzerland.
Amberg insisted he ride the track and Koblet became national amateur pursuit champion in 1945.
He turned  professional in 1946 and won the New York and Chicago six-day races.
It was after the races that he developed a love of the United States, driving to California and Florida.
He had learned English by watching American and British films.

He won the Swiss pursuit championship every year from 1947 to 1954.
In 1947 he finished third and in 1951 and 1954 second in the world championship.
