[EX Q]: Question: For how many years did Williams compete with the ACBB in France? Passage:In 1979 Williams won his first British National Hill Climb Championships setting a new course record that still stands to this day. A rival, Andy Hitchens, who remembers it well, said: "Williams looked like he'd been on starvation rations for months — he was built like a sparrow. Some people assume that there was a howling tailwind that day, but there wasn't. It was sunny, but cool.” In 1980 Williams joined the Manchester Wheelers' Club and was expected to win International honours during the next two or three seasons. Later that year he won his first stage in the Sealink International finishing four minutes clear. However Williams was left disappointed in the National Hill Climb Championships that year beaten into second place by Malcolm Elliott by only one fifth of a second after being knocked off his bike whilst warming up and receiving a broken nose and severe bruising. At the age of 21 Williams competed for Great Britain in the individual road race at the 1980 Moscow Olympic Games. He was sponsored by Harry Hall Cycles. Williams finished 47th, alongside Stephen Roche. At the end of the 1980 season Williams publicly declared his intention of living and racing in France for the 1981 racing calendar with a view to turning professional therefore joining the French club ACBB (Athletic Club de Boulogne Billencourt), Europe’s most successful sports club.
