Route description
Route description

All 4 races will take in the best the region has to offer. The coastal Gower 10K, half, marathon and ultra courses are set against an awe-inspiring natural backdrop of cliff tops, downland, woodland, sand dunes and world famous beaches. It will be a run to remember.

Did the Marathon in 2018
Nothing out of the ordinary for a coastal trail event. Course was more or less as expected. I keep going back-and-forth on whether I would've preferred to run in the other direction. The majority of the muddiest spots were towards the end when legs were quite wobbly already. Saw a few people slip and fall. Advice to future runners - shoes w/ excellent traction.
Did the Ultra Marathon in 2018
All was great , location , organisation, route. Only problem we had was my super supporter wife couldn't get to all the recommended view points, roads inaccessible, no parking etc.
Did the Half Marathon in 2017
Stunning views of Gower peninsula, bit wet and wild but worth it!
Did the Half Marathon in 2017
Stunning course around the Gower peninsula, albeit pretty tough on a long windy stretch of beach. There's a (mediocre) pub with a great view over the course to reward you at the end!
Did the Marathon in 2017
This is an epic course and a really well run series. Definitely worth doing!

We will be asking all registered participants to check in online approximately two weeks from the event. The Check-in process will result in a simpler event experience for you by removing the usual on-the-day administration. Within the Check-in process we will ask you to confirm your preferred postal address to enable your participant number and electronic timing tag to be posted and to watch the mandatory event safety video. There will be a baggage area for those that have come without a car.


This event is located in a remote and exposed location with little shelter. Do not underestimate how cold and wet it can get. Bring warm and waterproof clothes with you.
Starts will be conducted on a time-trial basis and there will be an online leaderboard running throughout the day. You will be released in ability order from the fastest to the slowest thereby keeping overtaking to a minimum on the trails. There are exceptions to the starting order where we have identified individuals with specific needs.

The briefing and start windows are as follows: Ultra - 8.00 to 8.30am, Marathon - 8.30 - 9.00am, Half Marathon - 10.00 - 10.30am, and the 10k - 11.00 to 11.30am. We recommend arriving at least half an hour before your race briefing starts to allow time to park and register. Registration closes 15 minutes before your briefing and start window.
What is the cut-off time for the Endurancelife Coastal Trail Series – Gower?
There are cut-off times for the Marathon and Ultra races only. All Ultra and Marathon participants must reach CP3 (at 19.4 miles) by 14:00, and ultra runners must reach the end of the Marathon route (at 26.4 miles) by 15:00.
