Thomas was born to a rector from
Bettws, Bridgend, but moved to England when he gained a place at
King's College, Cambridge after winning a choral scholarship. At Cambridge, Thomas studied History and was a keen sportsman. He played cricket for the Cambridge seconds, represented the athletics team and won a Blue at rugby. While playing for Cambridge he was first selected to represent Wales in 1912 in a game against the
touring South African team. When Thomas was selected for the South African game he was chosen against a stipulated agreement, that stated that no Welsh player could be chosen to represent the country if they played within the London area, but did not play for
London Welsh. Eight selectors travelled to Cambridge to watch Thomas play in a Varsity match which saw Cambridge victorious for the first time in seven years. The Thursday before the game, Thomas was named in the squad at a conference at the Queens's Hotel in
Cardiff. Wales lost the game 3–0, but at one point after Thomas attempted a drop goal, the crowd mistakenly believing that the kick had succeeded, cheered thinking that Thomas had won the game for Wales. Thomas would play only one more game for Wales, under the captaincy of
Tommy Vile, in the team's opening match of the
1913 Five Nations Championship against England. Wales lost the game and Thomas ended his international rugby career without a win. Thomas left Britain to take up a post in
Calcutta. While in Calcutta he joined and later became captain of the Calcutta Football Club.
