Hardeep begins his journey along the Mersey beside the River Goyt in the Peak District, the main tributary of the Mersey.
He visits Stockport, which is the official beginning of the Mersey, and spots the plaque which announces that fact hidden behind a Sainsbury's store.
From there, Hardeep ventures on to the Manchester Ship Canal and eventually reaches Liverpool's Albert Dock.
