Limitless Trails are very excited to be offering our very first Ultra marathon 50 mile / 80 km - on the Beautiful Black Mountains deep in the heart of the National parks.

This long distance challenge is one that will fulfil the elite and seasoned runner besides also offering amazing support for the less experienced trail runner who may be looking to step up a gear and attempt a greater challenge with the knowledge that they will be receiving incredible support and checkpoints throughout the duration of the run. Support crews and supporters will be most welcome during the event.

What you can expect

Friday afternoon the Team will welcome you to Race HQ – camping and parking will be available close to the start of the race. Registration and kit check will be available for an easier pre-race morning. For those unable to attend Friday please do not worry as a gentle start time of 8am will allow everyone a stress-free race morning. Registration will be open @ 6am – race briefing will be 7.30am

There will be a drop bag zone – items left at your own risk


This Trail Challenge is a self- navigation experience however we will be supporting certain areas that may lead to some confusion with flags and signs. Our pledge not to use tape stands. Participants will be tracked by our team throughout the entire race. Family and friends will be able to monitor and support each and every one of you. A GPX file and a map will be provided.

Each competitor will pass a stringent kit check during registration and at the main CP Zone on route. Mountain Rules set by the Local Mountain Rescue Team must be obeyed.

There will be incredible support on your challenge, first class Medical support by Nomad Adventures and mountain medics on the route. Our aim is to ensure that your experience will inject confidence with the knowledge that  the Limitless Trail Team will do everything to make this challenge an amazing achievement and experience, whether it’s your first attempt at a 50miler or not, hopefully it will inspire you to achieve and fulfil future goals and aspirations that you may have to push that bit further.

On route we will be supporting you with 4 Check Points plus 2 water stations,  but to go that step further we will be providing hot food at mid-way approx. 25miles – 40km – Longtown .Medical advice given to any runner not to continue must be followed, if not then the organisers do not accept any responsibility if the participant  continues. They do so at their own risk. We will have a team physio on site to offer any light relief.

At this point you will we welcomed with hot & cold homemade delicious food, all dietary requirements catered for, hot and cold drinks and homemade cake. A chance to rest and recover.

Support crews, friends and families are more than welcome to attend the Eat Zone however we do ask that runners take president over all. Please keep noise down to a minimum due to this being a small residential area and be considerate when parking.

During the event you will also be supported by a full mobile medical unit, support runners will be on the course at various locations if needed for vital support – both experienced within this Mountain Range.

Brief route outline

Starting at Perth y Pia Llanbedr the route takes you straight up to the Black Mountain ridge- descending into the valley, forest trails before you begin to climb Mc Namaras pass to scale the summit of Waun Fach. Leaving this behind you then follow the ridge to Lord Herefords Knob taking in some spectacular views before heading down to your first Checkpoint at the base of Hay Bluff!  Refuelled and energised you once again climb to the The Offas Dyke Path and head towards the stunning Cats Back Ridge, leading you into the Olchen Valley and your next Eat Zone based in Longtown (approx. 25miles) when ready and refreshed you will once again cross the valley and climb back onto the Offas Dyke Path. Following the path, you descend into the breath-taking Abbey of Llantony where you will collect a band and fill up your water. Following the Beacons Way, you will then head back up to finally drop down over the famous Hattteral Hill and enjoy yet another small check point. Leaving here you once again start a climb towards the Sugar loaf Mountain – this will be your final check point. You continue up heading over the summit of the Loaf where you will once again descend to find trails that traverse the mountain before once again heading back towards the summit. Here you will see your final destination in the distance! The Black Mountains, after heading back down to cross the valley you then have a small road section before your last vicious hill, glorious to the finish (50 miles). After recovering with some delicious well-deserved hot food & a shower you can marvel at your incredible achievement.
