A Glasgow road-race began in 1979 as the Glasgow Marathon, and was run over the full marathon distance, over four loops around the centre of the city. This initial event set the challenging qualifying standard of 3 hours, which limited participation to 62 runners in the first year and 144 in the second. The third year dropped the qualifying standard and encouraged mass participation, with over 7,000 runners competing in the first Scottish People's Marathon. The race continued over this distance until 1988 when, faced with diminishing participation and little engagement from TV and sponsors, the event was run over a half-marathon course. The following year the distance changed again, this time to 25 kilometres, and for the first time the event was named the Great Scottish Run. This unusual distance proved unpopular with the elite athletes who the organisers had hoped to attract, and so two years later the race returned to the half marathon format.
