A group of top riders from across Britain are visiting Drumlanrig Castle in Dumfriesshire for the Scottish launch of the 2013 Tour of Britain.

The riders will visit the Scottish Cycle Museum at the castle, where staff will show them the huge comparisons between the build and speed of vintage bikes and modern race bikes.
