The Great Scottish Run is a series of mass-participation road running events, held annually in the streets of Glasgow 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 road race, 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.
