FOUR York friends are to undertake an epic hike through the Yorkshire Dales to raise money for anti-poverty charity Oxfam.

Gemma Robinson-Wilson, Casee Wilson, Steve Cooper and Greg Reynolds, who call themselves The Unbreakables, are taking part in the Trailtrekker challenge, which covers 100 kilometres (62 miles) in 30 hours.

The distance is equivalent to almost two and a half marathons and the ascent is equivalent to climbing Ben Nevis and Snowdon.
