You will be welcomed at registration by the PCR team, and start meeting other excited walkers and feel that pre-challenge buzz! You will be introduced to your Mountain Leaders for the all-important safety briefing, before getting laces tied and taking a group photo to mark the start of the day ahead. 

Then it’s time to set off into the mountains!

  • 07:30 | Arrival and welcome at the registration point
  • 08:00 | Challenge begins! You will be out in the hills for approximately 10 hours
  • 18:00 | All hikers are likely to be finished by this time
  • 18:00 to late | Celebratory after-party with evening buffet and awards

Fitness level

The Multi Peak Trek is tough so you'll need an adventurous spirit and an open mind. The more you exercise before the challenge, the more you will get out of the big day.

Guided challenge

You will be accompanied from start to finish by fully qualified Mountain Leaders, who are highly experienced, knowledgeable and entertaining! The leaders will be ultimately responsible for the running of the itinerary and the safety of your group, whilst ensuring you have fun on your challenge.

They will be carrying full safety equipment and mountain first aid kits at all times and will be in radio communication throughout. There will be approximately one Mountain Leader per 12 participants for that small-group feel and optimum mountain safety.


This challenge is a great adventure that will have you trekking up and down the highest mountain in Wales at a mighty 1,085 metres, therefore requiring a good level of fitness. The ideal training for this challenge is hill walking or stair-climbing. Most training should be part of an ongoing lifestyle, but if this is not the case then you should begin training at least one month prior to the challenge and gradually build up.


Remember to train in the clothes, equipment and especially the boots that you will be wearing on the challenge in order to get them worn in.

It is important that you come prepared with the correct kit for this challenge including:

  • Waterproof jacket
  • Waterproof trousers
  • Footwear should also be waterproof and most importantly should have good grip (sports trainers are not suitable)
  • Warm layers, including a hat and gloves

  • Accommodation
  • Bar
  • Cafe
  • Camping
  • Free parking
  • Mountains
  • Paid parking
  • Restaurant
  • Rural
  • Toilets

Why support PCR?

Did you know that prostate cancer is the most commonly diagnosed cancer in men?

1 in 8 men in the UK will be diagnosed in their lifetime, and that increases to 1 in 4 for black men. Prostate Cancer Researchis determined to provide a better future than this; what is needed is breakthrough treatments, and research is the only way this hope can be turned into reality. Thatโ€™s why PCR funds world-class scientists and their pioneering research to fight for the best possible chance and outcomes for men.

Patient focus is crucial. People with prostate cancer are involved every step of the way to ensure your fundraising powers research that is important to them, whilst also spear-heading innovative projects with patients at their heart. For example, it is known that diagnosis is an overwhelming time for many, with important choices to be made and real consequences to understand. Thatโ€™s why Prostate Cancer Research is launching a brand-new website next year, providing clear and accessible information about treatment options and side effects, based on hundreds of real stories from people who have experienced prostate cancer themselves.

Join this challenge and you'll be supported in your fundraising every step of the way, with an expert team on hand throughout and access to loads of materials and ideas to help.

Together, we can create a world free from the impact of prostate cancer.

The walk up and down Snowdon is invigorating and the place is stunning. The sense of achievement is beyond belief and it is a really great way to help eradicate prostate cancer. Jonathan Chorlton, two-time Snowdon challenge participant

The leaders were magnificent. The young Welsh lad had an amazing knowledge of Snowdon and the surroundings. Jon, Gray and Kev

Most enjoyable walk. I thank you for the opportunity to assist in this vital work, getting up from the chair and boring comfort zone into a healthy and challenging experience with my grand daughter.

Its really enjoyable to meet up with old friends and make new ones, especially in such spectacular surroundings. The walking fraternity are always great to be around and the atmosphere at these events is always first rate. John

There was no doubt that this was a truly amazing experience. Every corner had a new view, and another challenge. Getting to the peak was the ultimate, knowing then that the monies raised would truly be safely donated. Lee
