The Marathon de Gwyr (MdG) is our summer challenge (the wintry image at the top is just to add an appropriate sense of foreboding). And it’s a magnificent one. It consists of 3 consecutive days of fell-running across the stunning Gower peninsula, covering a total distance of 58 miles. Unlike The Darth Mannion there are no sea-dips or river runs, just beautiful landscapes and stunning coastline. Local ales are tested every evening.

You can find write-ups of some of the previous Marathons de Gwyr here (sorry the latest ones aren’t yet here; we’re still reminiscing):

MDG I Write-up

MDG II Write-up

The MdG takes place each summer and will consist of 4 stages:

Stage 1: Day 1 Afternoon – 19 miles

Stage 2: Day 2 Morning – 12 miles

Stage 3: Day 2 Afternoon – 9 miles

Stage 4: Day 3 Morning – 18 miles

Each day finishes on a beach giving runners the option to cool off in the sea. Participants are encouraged to run the full distance; however you can just take part on the final day (and endure the disdain of the 3-dayers).

Internationally recognised Darth Peloton System

Similar to The Darth, the MdG is an inclusive challenge and not a race. It will utilise a peloton system and there will be no static marshals. As such runners will be expected to run together, and not faster (or slower) than their designated peloton. Multiple pelotons will be utilised at the half way point of each stage to cater for different abilities.

Accommodation and Clothing

Campsite accommodation will be organised for all runners. A two-course meal will be provided each evening at the campsite pub. Warm breakfasts and lunches will also be provided. Participants will be expected to bring their own camping equipment, as well as sufficient warm clothing. Equipment will be transported by MdG vehicles.

MdG Summer Party

The post-run social is an extremely important part of the MdG. After the final stage runners will be invited to a BBQ at South Gower RFC and then in the evening to The Valley Hotel, also in Bishopston. Food throughout the day is free for participants.


The full cost to take part in the 2019 event (likely in late-June) is around £225.  This includes:
