From Jubilee Park out via Horsington-Minting-Hatton-Panton-to Belmont TV ariel then down into Donnington out through Goulceby returning via Hemingby and Horncastle through Old Woodhall
Stiff climb out of Goulceby to what is arguably the highest point in Lincolnshire so you will need to be fairly fit for this one.
If the weather is bright it's a superb winter ride seeing trhe best of Lincolnshire countryside.
