Llantwit Major 10k


The Llantwit Major 10k was set up to honour the late David Synan's love of running.

After the first trail event of August 2015 was such a success the committee and volunteers decided to make this an annual event. The 2nd LM10K in 2016 built on the success of the event, and doubled the field of runners.

This event was organised by people who are passionate about running who wish to encourage all generations to get active and just maybe 'enjoy running'. This event was made possible by the amazing support of local businesses.

The course is mainly off road, through ancient woodland, public footpaths and farm lanes, taking in the Glamorgan Heritage Coast and offering cliff top views across the Bristol Channel to Somerset and Devon and inland across the beautiful Vale of Glamorgan.

10km Race
The 10 kilometre race is the headline event. Starting near the centre of the historic town of Llantwit Major the route includes a very fast downhill start which takes competitors off tarmac within 1500 meters when it leaves the road and goes into the nature reserve. 

The course remains off road for the majority of the distance, through ancient woodland, public footpaths and farm lanes, taking in the Glamorgan Heritage Coast from Castle Ditches to Summerhouse Point with stunning cliff top views across the Bristol Channel to Somerset and Devon and inland across the beautiful Vale of Glamorgan. 

Turning back inland past the water stop, it remains almost entirely traffic free until the last 800 meters when a shallow but challenging gradient tests the front runners tactical and sprinting abilities back to the finish line.

5km Race
The 5 kilometre race is intended for those who are new to running, unsure about running or simply prepared for a challenge but not confident of doing a full 10k race. It will not be formally timed so you will need to take a watch. 

The route is chosen to offer a challenge so it will start at the same spot as the 10k event and use tarmac roads, all downhill for the first 1500meters until it levels out across a meadow along the beautiful Colhugh Valley, eventually turning at Llantwit Major Beach before retracing the route back to the finish line. 

On the last section some competitors may find themselves being passed by the front runners of the 10 kilometre race! Do not be demoralised! Give them a cheer. It does not mean you are slow! They are just quicker than you; it’s all about taking part, challenging yourself and feeling a sense of achievement at the end.

1km Race
This 1K race is sponsored by FitM8 and is not intended for elite or serious runners. It is open to children, families and individuals of all abilities and disabilities. 


Anyone can enter the 1K race but it is intended for children and older competitors, to help them realise there is more to life than X.box, PS4 and day time TV. Adult entries who blast around the course, finish first and break the tape with arms aloft and a Mo Farah grin will be missing the point somewhat. 

If we can convince one child or non-athlete to get off the sofa and become active the race will have served its purpose. Parents and Grandparents are welcome to run with their children and you too will get a number for posterity to show you did it! The course is entirely enclosed within the rugby club field with no exposure to traffic whatsoever.
