Based in the local YMCA, the club was founded in 1921 and was then known as Port Talbot YMCA Harriers Club.
Under the guidance of Arthur Williams the Harriers were ranked third best club in Wales for many years. One of the early stars was long distance runner Ike O’Brien.
Early in 1961, after being denied the facilities of the YMCA, Arthur led a movement to form an independent club. At a public meeting held in the Municipal Buildings on February 9th, 1961 Port Talbot Harriers and Athletic Club was born.
Then based in Dyffryn grammar School, the winning tradition was carried on from father to son when, within a few days of the formation of the new club, Jim O´Brien won the Welsh Cross Country Championship at Seven Sisters.
An enthusiastic administrator, Arthur Williams was President of the Welsh AAA for seventeen years and remained a leading light at the Port Talbot club right up until his death at the age of 90 in 1983.
