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 they leave the road and enter 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, Devon, and inland across the beautiful Vale of Glamorgan.

Turning back inland past the second water stop there is a tantalising glimpse across country of the finish line, still 3 kilometers away. The race remains almost entirely off road until the last 600 meters when a shallow but challenging gradient back towards the town tests the front-runners tactical abilities.

A sharp turn into the rugby club fields and less than 200 meters to the finish beneath the western rugby posts. An opportunity for a sprint finish and a welcome drink.

5K Route Info

The 5-kilometre race is for those new to running, unsure about running or simply prepared for a challenge but not confident of doing the full 10k race.

The race is not formally timed so you will need your own watch.

The route is chosen to offer a challenge. It starts at the same spot as the 10k event and is on tarmac, all downhill for the first 1500 meters until it levels out across a meadow along the beautiful Colhugh Valley. Competitors turn at the water stop at Llantwit Major Beach before returning up the valley, avoiding the narrow beach road, and retracing the route back to the finish line.

On the last section, some competitors may find themselves being passed by the 10-kilometre race competitors! Do not be demoralised! Give them a wave and a cheer. It does not mean you are slow! They are just quicker than you are; it is all about taking part, challenging yourself and savouring the sense of achievement as you finish, triumphant, under the posts.

The 1k race is intended for children and those who don't feel confident enough to run the full 10k. The route is entirely within the confines of the rugby club field for a safe, traffic free route. Adults running the race will have missed the point if they win the race and cross the line with arms raised like Mo Farah.
