A 23-year-old man is attempting to break a world record by becoming the youngest person to traverse Mount Everest.

In April 2015, Rupert Jones-Warner, from Chichester will attempt to not only reach the summit of Mount Everest but then take on the descent down the mountain's Tibetan side via the north-east ridge.

Rupert's challenge will first entail a 45km climb, beginning on the Nepalese side of the mountain with an ascent via the south-east ridge, which is expected to take 57 days in total.

The descent should take three days but is considered to be the most dangerous part of the climb, with 80% of fatalities occurring on the way down from the 8,848-metre (29,029ft) summit of Everest.

As well as attempting the complex climb, which to date has only been accomplished by 32 people, Rupert is also aiming to raise £50,000 for Chestnut Tree House children's hospice.

Rupert said: "I am so pleased that my dream of climbing Everest is actually becoming a reality. It is amazing to be a able to support a charity like Chestnut Tree House and it is great to have them help support me and make this dream come true."

Linda Perry, director of children's services, said: "At Chestnut Tree House we are familiar with young people tackling the unimaginable: we help children and young people to make the most of their lives, however short. Everyone at Chestnut Tree House jumped at the chance to be involved in supporting Rupert's dream and endeavour."

The cost of Rupert's climb is being funded by his employer Darwin Property Investment Management, and other organisations including holiday company Hoseasons.
