Colleagues from a housing association in Chester-le-Street have signed up for a challenge to walk 100km in 30 hours.
Esther Windass, Peter Hewitson, Arshia Bhatti, and Craig Ball from Cestria Community Housing will join the Oxfam Trailtrekker 2013 challenge to raise money for the charity.
The team, known as Blister Blasters, will join more than 300 other teams to walk 100km through Yorkshire between June 1 and 2.
A back-up team, also from Cestria Community Housing, will support the group along the way by providing first aid, encouraging words and preparing hot meals.
Money raised will make a difference and change lives by providing clean water and sanitation during emergencies, funding long-term projects in areas such as health or education and help towards campaign work in developing countries such as Africa.
