Jack Woodcock, who first joined the Harp Cycling Club at Cookstown, County Tyrone in 1918, was one of the greats in the Irish cycling scene throughout the 1920s, known in particular for his sprinting power. In addition to representing Ireland at the 1928 Olympics in the road race event in which he finished 44th, he was also a member of the Irish cycling team (alongside fellow 1928 competitor Bertie Donnelly and non-Olympian J.J. Masterson) that competed at the 1931 Road World Championships in København (Copenhagen), Denmark. He was also a founding member of the Ireland National Cycling Association (NCA). Retiring from competitive cycling in 1932, Woodcock later worked at a post office in Dublin until retiring in 1963.
