from tamworth up m42 then onto a511 follow onto the a50 looking to pick up the a46 till saxondale (bingham roundabout) across to grantham on the a52 and out the back to ancaster. (aim for londonthorpe then at the highdyke (long straight road) turn left and go till you see a tank on the right thats ancaster paintball and karting.)
be warned this way has many average cameras and cameras dotted about grantham.
i can do grantham to tamworth snowdome in 1hour 15 ish this way.
