Cycling is a popular amateur sport, with 99 clubs throughout the country, from the Shetland Wheelers to the Stewartry Wheelers. At the elite level, Scots have been more successful at track cycling rather than road racing, although Scotland has a long history of time-trialing on the road. The lack of road races within the country, with not a single UCI-ranked event, is largely to do with the refusal of Scottish local authorities to close public roads to allow road races to take place safely. Scotland has three velodromes, one at Meadowbank Stadium, in Edinburgh, another at Caird Park in Dundee and a third, the Sir Chris Hoy Velodrome, which was built in Glasgow for the 2014 Commonwealth Games. The governing body is the Scottish Cyclists' Union.
