The Fenland region has undergone some of the most radical environmental changes of any landscape in Europe.

Looking at its mosaic of ruthlessly rectangular fields and carefully cultivated crops, its long straight dykes and roads, it is difficult to believe that this area was once a wetland maze of 'black waters overhung by fog', 'wooded islands', and the 'windings of tortuous streams'. But this is the landscape, already very ancient, that St Guthlac's biographer described in the 8th century, and which Fenmen of the 18th century would have recognised.

This cycle route will take you through 150 million years of landscape change, from monstrous marine reptiles to medieval marshes and the bricks that rebuilt London.
