Merthyr Tydfil Half Marathon 2020


Are you looking for a challenge in 2020? In 2019, over 650 people ran the Griffin Mill Merthyr Half Marathon, making it the biggest race since it launched in 2014.

The half marathon is organised solely by volunteers who represent Merthyr Running Club.

Entries are now open for Griffin Mill Merthyr Half Marathon 2020 and close on March 18, 2020 at 10.45pm.

The event starts and finishes at Merthyr College, where there will be a baggage drop and toilet facilities. The course utilises the Trevithick Trail and the Taff Trail, so it is predominately run on road.
