The City of Glasgow Regatta is one of the oldest annual sporting events in the country, and is now at about the 185th edition. I am no expert on rowing, in fact it seems to have little recorded history in Scotland, but in the 19th century this event was a major attraction in the city and drew huge crowds to the banks of the Clyde. 1829 was, of course, also the year the Oxford v Cambridge boat race started, which gives some idea of the Glasgow Regatta's antiquity and importance.
