I live in Pinewood, and commute to the town centre... it's about 3 miles as the crow flies... but i never could read maps and find myself leaving an hour early for work every day and taking a ride out into the countryside...
Next time I go out at the weekend, I'll take that route, I know the one you mean... you can also take the road out towards coddenham and ride through the lanes out there... it's a nice quiet lane all the way to woodbridge as far as I remember...
My aim is to hit 6000 miles this year too, reckon I should hit it... just about.
