Starting out at Cafe 53 head towards the Sidmouth road (A3052). Follow the road until you reach Lyme Regis, before joining the A35 and stay on this road until you reach Chideock. At Chideock turn right and follow the lane down towards Seatown and the Coast. Once you reach the picturesque beach you'll find the Anchor Inn which is an ideal stopping point before you head back along the route from which you came.
If the sun is out and you are going for an afternoon blast be sure to take Sunglasses, travelling out to Seatown (west to east) you'll be riding directly towards the setting sun. The roads for this route are in relatively good condition, however, sections of the Sidmouth are aligned with trees - so take care.
