Event Organiser - Ellen Wood

Our day of trail running will be held in the beautiful national park of South Wales - the Brecon Beacons. The weekend will be full of trail running, sports therapy, camping, and much more including  freshly brewed coffee from our very own Emma - Moon & Back coffee.  The vibrant village of Llangynidr means that you will have everything close enough on hand to ditch the car for the whole bank holiday. Bring the kids, wellies and dogs and let them explore the local trails and hidden gems. Canicross very welcome ;)

What you can expect from this event 

Friday evening the Team will welcome you to Race HQ at Llangynidr – camping locally  and parking will be available for those not camping. Registration and kit check will be available for an easier pre-race morning. For those unable to attend Friday please do not worry as there will also be registration available from 6am-7am Saturday morning. Transport to the start will be arranged. 

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 team 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 50/26 miler 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  Check Points and water stations,  but to go that step further we will be providing hot food where possible. 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 of physiotherapists on site to offer any light relief.

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

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.
