With your back to the Clanfield Arms turn left to walk away from the main road. Stay on the pavement to nearly the end of the village. Turn right onto Marsh Lane, by the dog waste bin. Pass a farm and water treatment unit, and then it's pretty safe to let your dog off-lead, depending on how reliable the recall is of course. Short walk When you see a turn to the right, this is the one for you if you're looking for a short walk (1 mile/20 mins). Long walk Otherwise go straight on along an unsurfaced road, past some farm buildings and with a drainage channel on your right. After 30 mins walking (from the start) you'll be near to the Radcot Cut bridge and the start of a series of water channels. It feels a bit like a mini-Somerset levels. This is a good place to turn round for a 60 minute/3.5mile leg-stretch. You could also drive to Marsh Lane at the start of the walk and park politely by one of the field entrances. This would miss out the on-lead stretch at the start. The track is very pot-holed in places so this depends on your vehicle.
