Sands of speed
This is the name of a 7 mile (11 km) stretch of sandy beach located on the south Wales coastline between Tenby and Swansea . The most impressive feature of this beach is its flatness and straightness at such a long length. You can see the satellite view below.
In the early 20th century the sands were often used as a racing course and later, in the 1920s, it was used for land speed records .
