This Saturday, Dylan Carlyon is going to climb three peaks in the Brecon Beacons.

In one day he will scale Pen-y-Fan, the Sugar Loaf, and the Skirrid.

When he has completed this feat, Dylan will have ascended a total of almost 6,500 feet of steep terrain and scaled the tallest mountain in the southern part of Great Britain (Pen-y-Fan).

This challenge is far more than an easy trial for anybody, but what is even more impressive than the endeavour itself, is that Dylan is only six years old.

Dylan, with the help of a support and collection team, is undertaking this mammoth task to raise money for a specialised paediatric hydrotherapy pool for local children. He was inspired to do so after experiencing the need for such facilities in the case of his little brother Hari.

Hari was born 2008, and despite the beliefs of medical professionals who said he may not make it, but he defied doctors predictions, proving that he had a "hunger for life".

Soon, Hari began to display signs of delayed development and was found to have hyper-mobility in his joints, resulting in an inability to walk or crawl in the first years of his life.

During a course of hydrotherapy treatment in an adult physiotherapy pool at his local hospital, staff worked to build up his muscle strength and core stability in a series of sessions.

After the course of treatment, and to the delight of his parents David and Ceri, Hari took his first steps at the age of two.

Dylan supported his little brother through every step of his therapy, watching every one of his pool sessions and encouraging him throughout the journey towards his first steps.

It was during this time that Dylan and his parents noticed the shortage of facilities available for paediatric patients such as Hari.

Dylan was dismayed by the shortage of time that his younger brother was able to use the pool facilities.

The hydrotherapy pool that Hari was treated in was a shared facility, which was only available for paediatric physiotherapy for a limited amount of time a week.

The local area lacks a dedicated pool for children meaning that current paediatric patients have only one hour a week to use hydrotherapy facilities. This means that around 500 children a year are left without necessary therapeutic treatment they need.

One day, Dylan came home from school with a leaflet about the Noah's Ark Appeal, who have raised phenomenal support for the children's hospital, and through their Splish, Splash, Splosh campaign, are raising money for a dedicated hydrotherapy pool for children.

The campaign needs £500,000 to build a state of the art pool with changing rooms, showers and hoists to lift patients who may need help getting in or out of the pool.

These facilities will benefit a wide range of paediatric patients like Hari with delayed development, but also those who have suffered from traumatic injury, neurological conditions, bone cancer or respiratory problems such as asthma.

Dylan was enthusiastic to know what he could do to raise money for the Noah's Ark campaign to help his little brother and other children in the South Wales area who would benefit from the new facilities it would create.

To achieve this he decided to do a sponsored climb of Pen-y-Fan, the Sugarloaf and Skirrid with the help of family and friends on Saturday, August 6.

So far he has raised a fantastic sum of £1,560, but with help and support he could raise even more.

Throughout June and July, Dylan has embarked on preliminary hikes of the three peaks with his father David, mother Ceri and siblings Hari and Eleri.

News of the climbs on his fundraising website JustGiving.com speak of him racing up the mountains "like a whippet" only being slowed by his family trying desperately to catch him up.

On July 27 Dylan managed to scale Pen-y-Fan in just a few hours, receiving donations and encouragement from fellow ramblers on the way.

Three days later Dylan, along with Hari and Eleri dragged their father David up both the Sugar Loaf and the Blorenge managing to climb nearly 3800 feet in one day!

By all accounts it seems that Dylan has more than enough energy and enthusiasm to complete his challenge with time to spare.

Fundraising for his challenge is open now and will continue after the event so that anyone can help this enthusiastic and inspirational little boy achieve his goal.
