Beacons Waterfalls Marathon / 1/2 Marathon Trek

Trek Adventure

A beautiful marathon and/or 1/2 marathon trek taking in up to 10 of the Brecon Beacon's very best waterfalls on some very special scenic trails. You will begin by getting up close to the Sychryd Waterfall before stepping into the Mellte gorge to follow the classic Four Falls trail, (Sgwd Yr Eira, Sgwd y Pannwr, Sgwd Isaf Clun-gwyn, Sgwd Clun-Gwyn). Here you will witness the mighty power of these falls stretching right across the river. You may even want to experience standing behind one of them! Upon reaching the huge cave entrance of Cwm Porth we will cut across to the Beacons Way trail to reach our half way point at the historical Craig-Y-Nos Country Park and Castle for a spot of lunch. We then begin the trail Southwards to reach the highest Waterfall in South Wales, Henrhyd Falls before tracking back over to reach the Nedd Fechan decent with the final two falls of Horseshoe Falls and Sgwd Gwladys. This will be one awesome challenge!

The total ascent for this challenge is 900m over 26 miles so will be a full on day! There is also an 8 mile loop or 5 mile family friendly route to work in sync with the marathon trek for large scale events.

What is a Level 4.0 Trekking Challenge Like?

You are now moving into the realms of serious challenges - where you are likely to encounter rough and steep terrain, sleep deprivation – ie very long days, or even high altitude. In any case - be prepared for an event which is going to take you well past the limits of your comfort zone. Trekking days will be up to 13 hours, or slightly less if the event stretches over several days. The severity of the challenge may be magnified by various factors - and you will need to be more resilient - variable weather conditions, simple food and maybe camping – these factors forms a part of the challenge. You need to be in good shape to undertake any of these events, and you need to be training regularly. The height gain each day is greater than for level 3 - so expect plenty of hills! A level 4 challenge would involve a very long day (in excess of 28 miles) or some serious hill climbing (multiple peaks in one day) - or possibly both!


How Fit Do I need to be to join a Level 4.0 ‘Trek’?

To participate in these events you need to be in very good fitness. You enjoy taking exercise, and do it regularly (a couple of times a week minimum). You may well partake in several different types of activity, possibly including the gym, swimming, running, or circuit training. You probably are capable of running up to 5 or 6 miles, but in a good steady speed (around 9-10 minute miling). If you do not run - you should be regularly undertaking challenging walks or other strenuous exercise. You should be comfortable walking 17-19 miles in the English lowland countryside.


Medical Issues

Please note, it is extremely important for this physical challenge that you are in good health. If you have any pre-existing medical conditions, please consider carefully whether you should be joining the challenge. Please ensure you fill in the booking form accurately and honestly, this is important. In the case of serious conditions (epilepsy, diabetes, heart conditions, recent illness or operations), please discuss the challenge with your GP. Please also ensure you notify us of any allergies or similar.

You should be used to walking reasonable distances each day to contemplate this trek. It requires stamina and good aerobic fitness - but good willpower will also come in handy! Failure to disclose medical conditions is a serious omission - that could have serious repercussions on any of our challenges.

Safety Information

By nature all activities contain an element of risk.Your leader will be first aid qualified and will carry the appropriate safety kit for the activity, such as mountain safety shelters, walking rope and from time to time mobile radios. Safety equipment carried will be appropriate to trip. The leader's primary role is to ensure your safety, but it is your responsibility to listen to their guidance and instructions.



At most times of year the weather can go either way from warm temperatures to freezing cold – so be ready for anything – make sure you pack according to the list! Remember that layers are the key, allowing you to adjust your level of warmth more easily. We will almost certainly experience a little rain during the weekend, so make sure you have suitable waterproof gear—both jacket and trousers.
