Half Marathon



Age 17 & over

  • 13.1 miles trail running


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 of 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. The marathon has approximately 1300 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 but some navigation skills will be required (the course is marked but signs have been moved in the past and we don't want you stranded miles from home!) The winner's time is normally around 4hrs 50 so please expect to be out for longer than you would for a road marathon.

This event is part of Radyr and Morganstown Trail.
