In addition to Senior 1st and 2nd XV teams the club also has a thriving youth rugby section with players at every age group ranging from Primary 1 through to under-18.

During those first seasons notable results were achieved with the likes of Craigielea, Glasgow High School FP, Bishopbriggs, Lenzie and Bellahouston Accies all failing to defeat the newcomers.

Following such a promising start, and having established themselves on the ‘circuit’, the Great War brought matters to a temporary halt with play not resuming until 1922 when the club were members of the West District Union League.

Langrish, later to gain 4 caps for Scotland, were involved on the playing side for Uddingston and normal service was quickly resumed.

P. Laurie Duff was to go on to become Uddingston's most successful player, moving to Glasgow Accies from where he earned 6 Scottish caps between 1936 and 1939, and achieved the ultimate rugby accolade when he was selected to tour South Africa with the 1938 British Lions.

Things were looking good, but the departure of a number of key players over the next few seasons saw fortunes dip once more with exception of one notable fixture in 1962 against Hamilton.

With Hamilton leading 6–0 at half time Uddingston stepped up several gears to secure an 8–6 victory, their first against their local rivals, Douglas Steedman scoring the winning try.

By 1981 Uddingston had once more climbed into the National Leagues reaching Division 6 in 1983, narrowly losing 16–6 to Heriots FP in the final of the Kilmarnock 7's that same season.
