Basically 332 south out of Carrollton to 164, 164 sucks due to road condition, to 115, to 151, to 250, to 800 south, last half of 800 rocks! but be careful there are no curve signs, turn left on 7 and there is a gas station and restaurant, then take the Fly Ferry across the river, $3 per bike, then 2 towards Marietta, which is boring and straight, then 807 across the river, then left on 7, sucks, straight and congested, to Marietta, then right on 60 north, boring and straight, to 83, which is always fun up till you get past 70, then to 93, then to 751 which is fun and ends at 77, then left onto Stone creek road which is a blast. 39 back to Carrollton. Slightly under 300 miles. http://g.co/maps/p39eh
