The Cylchfordd Dewi Sant/Circuit of Saint David's (formerly Launch Energy Motorpark) a 2.38 mile (3.808 km) road course near Llanrhystud, Wales that hosts the Round of Wales in the TM Master Cup Series. The inaugural event was held due to the success and popularity of Alan Hodges and Michael Sykes, and has been held annually since.

The Circuit of Saint David's ("Cylchfordd Dewi Sant") was a club level circuit that Launch Energy invested heavily in redeveloping for TMMC level races, so much so that it was named as "Launch Energy Motorpark" by the time the trucks had arrived for first practice. The track is also a prominent round of the National Touring Car Championship.

At the end of Launch's naming rights the original name was originally put back to "Olhrain Dewi Sant" by those at Launch, however the proper Welsh for "Circuit" ("Cylchffordd") was successfully restored to the official name by locals.
