When Celtic FC was founded they signed up several Harriers including Tom Maley and his brother Willie, who went on to become one of their greatest managers of all time and incidentally President of the Scottish Amateur Athletics Association (SAAA).
As far as racing was concerned, John Wright won the national Junior Cross Country Championship twice and the Senior Men's team was third in 1955.
Between 1960 and 1985, the club performed well in all the endurance events with athletes including Phil Dolan, Robert McWatt, Allan Faulds, Ian Leggett and Doug Gemmell all representing Scotland at various levels.
In track and field the sole internationalist was Ian Logie, who competed in the pole vault for Scotland three times in one year in the mid-1960s.
There were four GB representatives at Under 20 or Senior level (Des Roache, Ewan Calvert and Grant Graham at 800/1500 and Jason Allan in the high jump) as well as 20+ Scottish internationalists.
In 2003 Graeme Reid won the Scottish National Senior Men's Cross Country Champion to be the first Clydesdale to win it since Dunky Wright exactly 80 years earlier.
