The challenge

Trek for loved ones and bring help and hope to everyone living with dementia. Trek in the heart of Brecon Beacons through wild moorland, past tumbling waterfalls and sweeping mountain slopes.

‘The whole day was one of the best ever experiences, there is such a feel good, happy atmosphere. Seeing the finish line and hearing the music, the MC and the cheers from the crowd lifts you up and all your aches & pains disappear and you literally float over the line and the pride in what you have just achieved is exhilarating’ 

- Dave Trek26 participant 2022

The route

The 26 mile route begins with a steep climb up Cefn Cyff to reach the peak of Fan Y Big at 717m. Then the route turns on to the Beacons Way in the forest above Talybont Reservoir. On reaching the small village of Talybont on Usk, the route then joins the Monmouthshire and Brecon Canal tow path, and edges around Brecon town centre alongside the Usk River before the final uphill section to the finish.

The 13 mile route begins in the little village of Llanfrynach. You will ascend Pen y Bryn before following the Beacons Way to your lunch stop. From there, you'll continue along the Beacons Way to the top of Fan Y Big, before descending to the finish line.

Fundraising Target

Your fundraising will ensure that people facing a dementia diagnosis won't be alone. The money you raise will pay for vital services and research into treatments to improve people's lives. 

13 miles

  • Registration fee: £20
  • Fundraising target: £200

26 miles

  • Registration fee: £25
  • Fundraising target: £300

Your fundraising target covers the cost of your place on the event and still have plenty of money left to help us get closer to a world without dementia.

It's always best to hit your target early, so once you sign up you'll have access to our exclusive online event hub packed full of helpful fundraising tips and tools. Plus, by hitting your target, you'll bag yourself a FREE trekking top to wear with pride on the day.


The route is designed to be challenging but is achievable for most people provided you train well in advance. When you sign up we’ll email you a training guide to help you prepare.

The minimum age limit for the Trek26 series is 14. All participants must be at least 14 on event day. 

If you're under 18 you'll need an adult to take part with you, who also needs to sign up online and fundraise.

Absolutely! You can create your team when you register by clicking 'Create'. To join an existing team click on the ‘Find’ button and type either the team name or the name of the team captain. Every member of the team must register for the trek via the website (joining a team on Just Giving is not a valid entry for the trek).

Your fundraising target is still £200 per person for the 13 mile route or £300 per person for the 26 mile route, but you're welcome to combine your targets into one team total. 

When you register as a Team Captain, your team members will receive 20% off their registration fee when they sign up. Details of the discount will be supplied to the Team Captain upon registration.

You will need to be able to carry all essential kit required for the challenge e.g waterproofs, layers, water (minimum 2 litres), sun cream, snacks. Check the kit list to be sure of everything you will need.

Make sure you have trained with your backpack, carrying everything you need, so that you are used to trekking with your pack at full weight.

This route is categorised as Very Tough and the terrain is reflective of that. This is a hilly route, with a total elevation gain of 932m on the 26 mile route, and 1070m on the 13 mile route. You'll undergo some steep ascents and descents on rocky and uneven mountain pathways so you may want to bring walking poles for extra support. 

The 26 mile route begins with a steep climb, scaling Fan Y Big to a height of 717m, but we promise the views over the Brecon Beacons will be worth it! You will then head to more gentle, undulating terrain mostly on farmland and the canal towpath for the second half. The 13 mile route begins with a steep climb, scaling Pen y Bryn. You'll walk along well trodden but uneven mountain pathways as you head along the Beacons Way, before descending Fan Y Big on a steep decline to the finish.

We'll have members of the team spread along the route, and a back marker walking at the rear. The route will be well-marked with brightly coloured marker arrows and there will be extra marshals at any sections that are less straightforward. 

There'll also be staffed rest stops along the route – usually one halfway lunch for the 13mile route and one in the morning, one in the afternoon, plus a lunch stop for the 26 mile route. We’ll be on hand to provide help and plenty of encouragement and there will be first aid support, as well as toilets.

This event is not a race; everyone should be able to trek at a comfortable pace. In order for the event to be managed safely, there will be a cut-off time.

The 26 miles should take approximately 9-10 hours but can take some walkers up to 12 hours. The 13 miles should take approximately 5-6 hours but can take some walkers up to 8 hours. 

There will be facilities at the event hub (where you start and finish) and each rest and lunch stop along the route.

We provide food, hot drinks, and water re-fill stations for every participant on a Trek26 event. We plan these rest stops every 6-7 miles to ensure our trekkers are fully supported, with lunch at the halfway rest stop for each distance.

• The start line - A breakfast snack, hot drinks, and water re-fill stations.

• Rest stops - A selection of snack bars, chocolate, fruit, crisps, hot drinks, and water re-fill station.

• Lunch - A selection of sandwiches, snack bars, chocolate, fruit, crisps, hot drinks, and water re-fill station

If you smash your fundraising target one month before your event day we’ll send you out a free trekking top. You don't need to get in touch to claim it - as long as you have hit your target on your JustGiving page or paid in cash donations, we'll send out your top automatically. 

If you hit your target after the one month deadline you can still claim your free trekking top on the day (visit our merchandise stand)

If you are fundraising in a team, please let us know by creating a team when you sign up so we can make sure you all receive your tops.

We carry on! Do make sure you check the kit list and come prepared for all types of weather.

No, we’re afraid not, everyone taking part needs to be fully registered and fundraising to beat dementia.

Unfortunately, dogs are not permitted to take part in the trek due to safety issues and due to us trekking on privately owned land.

They are welcome to be on the event hub with friends and family but must be kept on a lead and the person looking after them is responsible for cleaning up any mess. 


Not a trekker? You can still do something incredible and make a difference to people affected by dementia.

We are looking for enthusiastic volunteers to cheer our trekkers over the finish line. We'll kit you out with an Alzheimer's Society t-shirt and provide you with everything you need to give our trekkers an amazing event day experience.

You'll help to set them on their way to raising even more money to change the lives of people affected by dementia. And we can guarantee you'll have a great time!
