Great Scottish Run

The Great Scottish Run is a series of mass-participation road running events, held annually in the streets of Glasgow, Scotland in October. The event began as a full marathon in 1979, but later changed to a weekend of shorter events. The weekend now includes short events for children, a 10K roadrace, and a half marathon. The 2013 event, which was sponsored by the Bank of Scotland, featured over 30,000 competitors. It is the largest mass-participation sporting event in Scotland.

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 15 ¹⁄₂ miles (24.9 km), 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.

After the running of the 2016 event, a number of runners raised concerns that their GPS watches reported the route was shorter than the prescribed distance. The race organisers, The Great Run Company, later confirmed that the course was 149 metres (163 yd) too short; the inaccuracy came from both a setup error in one section and errors measuring the route when roads (which are closed to traffic during the race) were in normal operation. The 2016 men's event winner, Callum Hawkins, had broken the Scottish half marathon record, but the non-regulation distance invalidates this record.

The half marathon begins in George Square and immediately heads steeply up St. Vincent Street, going west through the city's commercial centre and Anderston. Runners then join a sliproad of the M8 motorway and cross the River Clyde on the Kingston Bridge, part of which is closed to vehicle traffic for the Sunday morning of the event. The next portion of the race takes place in the city's south side, heading through streets of the Kinning Park area, and then on paths through Bellahouston Park and heading back northeast toward Pacific Quay and the river. The course then crosses the Clyde again, this time on the Clyde Arc. From there runners head west along the river side, past the Scottish Exhibition and Conference Centre before doubling back around the Riverside Museum to head east along the Clyde, and back through Anderston, with runners entering Glasgow Green through the McLennan Arch for the finish.
