If you're looking for a classic ultra distance in a stunning setting, the Ultra X Spring Trail Series 50 Miler is a truly brilliant race. Set in the rolling hills of the South Downs National Park, this event is a proper runner's ultra: fast, beautiful, and exceptionally well-organised.
The race hub is based at the picturesque Cowdray Estate, which not only provides a great start/finish line buzz but also makes the logistics dead simple. You park right at the event village, which is a massive plus.
This 50 mile ultra marathon follows the Serpent Trail, a path that winds its way through the very best of the local landscape. You'll run through glorious woodland, across open lowland heath, and over gentle greensand hills.
One of the key features of this race is its runnability. The organisers rate the course low on technicality (1/5), meaning the paths are well-maintained and fast. While it's an ultra with all the climbing you'd expect, you won't be held up by treacherous terrain. It’s an ideal course for anyone stepping up to the 50-mile distance for the first time, or for a seasoned runner looking to post a fast time.
Ultra X has a reputation for its superb, supportive atmosphere, and this event is no different. The 50-mile race typically kicks off in the morning (around 7 am), giving you plenty of daylight for your adventure.
The course is fully marked, so you can switch off the navigation and just enjoy the run. You'll also be supported by: Full medical cover, Well-stocked aid stations, A drop-bag service to the halfway point, A fantastic finisher's medal
For a friendly, scenic, and brilliantly organised 50-mile race, the Ultra X Spring Trail Series is hard to beat. It’s a firm favourite on the UK ultra calendar for a reason. For full details, please visit the official Ultra X website.
