Hereford Expedition Group (HEG) is a voluntary organisation dedicated to providing young people with a transformative and fulfilling experience in a challenging environment. Founded in 2005 by Giles Smith and Andy Preedy, inspired by their own expedition to Everest (Kala Patthar) in 2004, HEG has been creating life-changing opportunities ever since.

In 2007, HEG organised its first expedition to coincide with the 50th Anniversary of the Duke of Edinburgh's Award. Sabah, Malaysia was selected as the destination due to its cultural diversity, challenging environment, and communities in need of support. This expedition marked the beginning of HEG's commitment to offering young people from all walks of life the chance to participate, regardless of their gender, social/economic background, cultural background, or religious affiliation.

HEG operates on the core principle that any young person aged 16-18 living in Herefordshire can embark on an expedition. The group values teamwork, individual and team fundraising events and activities, and a shared dedication to personal growth and development.

The expedition itself encompasses four key elements: a physical challenge, a community project, a cultural experience, and a focus on conservation. These components combine to create a holistic and enriching journey, where participants can push their limits, make a positive impact, and gain a deeper understanding of the world around them.
