The Charlton Chase is widely considered as the premier night navigation team exercise in the South East of England.
Teams of four young people (aged 15 to 21) undertake a course through the South Downs National Park, requiring navigational skills and team work if they are to succeed.
The Charlton Chase event is run by Seaford College.
"Thank you are too small words to express our immense gratitude and respect for you and your team for the ingenuous organisation of Charlton Chase, providing a unique and engaging opportunity for young people to challenge themselves, extend their boundaries, redefine possible, develop endurance, learn teamwork, and find out that they can achieve beyond their expectations... among many other benefits. We fully appreciate all the hard work involved in running this event and are very grateful".
