'Monster Mountain': Former Merthyr Tydfil coal tip to host motocross race

A former coal tip on the outskirts of Merthyr Tydfil will this weekend play host to round two of the MX Nationals - a British motocross championship.

A 94-acre site situated on top of a spoil tip above Cwm Bargoed has been transformed into the biggest motocross track in the United Kingdom.
