It's 100 years since the First World War ended with the Armistice of November 11 1918. Nick and Fiona Jenkins set out to walk the entire Western Front - from the Belgian coast to the Swiss border - to find out what scars remain. They didn't even know if it was possible to complete their walk, but they discovered that much remains to be seen along the old front line. Join them on their walk to find out what they learnt - and share in the pain, the exhilaration and the sadness that they experienced.
