The Radyr Trail Half Marathon &amp; Trail Marathon starts in Wales' capital city, Cardiff, but you'll soon feel a million miles away as you leave the hustle and bustle behind you for idyllic trails and scenery.
​
The half marathon is an excellent trail run for new runners and veterans alike. You'll enjoy mountain views, woodlands, forest, and great camaraderie as you explore a range of trails and countryside paths. The highest point is the Garth mountain, the real star of the film An Englishman who Went up a Hill but Came down a Mountain (sorry, Hugh!). The last couple of miles finish in a flat nature reserve where you'll be rewarded with plenty of birdlife and squirrels darting around you.
​
This event is part of the Radyr and Morganstown Festival, with proceeds going to local charities. The route will be fully marked, with two checkpoints to help you on your way. The route is not easy; the winners came in at 1hour 45 minutes in our first race, however, don't be put off by the challenge. Our sweepers walked the entire route well within the cut of times, we will do everything we can to get you around.
​
A full description of the route can be found here.
​
 
The marathon has approximately 1,300 meters of climb, taking in the half marathon route above and adding an additional 13.1 miles of trails. This course is described by past runners as beautiful and brutal. A gpx and map will be provided.
​​
The winner's time is normally around 3hrs 30 so please expect to be out for longer than you would for a road marathon.

Navigation
​
Half Marathon
The course will be signed and should not require map reading or navigation skills. However, due to the length of the race, and wishing to keep the ‘exploring’ feel of being in the countryside, runners should expect some stretches where there may be no signage. Signs will be at junctions and pathway choices.

Despite the best laid plans, some runners may still lose their way. For that reason, people download What 3 Words. This will help us get you back on track ASAP.
​
The race contains 2 checkpoints with water and light refreshments.
​
The race will be fully supported by a professional medical team.​
​​​
​
​Marathon
The course will follow the route of the half marathon for the first three miles, which will be well marked. After this, there will be three circular sections that veer away from and then rejoin the same route as the half. Where the half route is well marked, the marathon sections will be not be marked though we will have marshalls at critical junctions to help you on your way
​
There will be  maps and brief description for the sections that are not on the half marathon route. There will be an expectation on runners to be able to navigate, partly because despite best efforts, we cannot check the whole route for sign damage on the morning of the race.

A map and gpx file will be provided with the marathon route.
