There's a new bike trail along the Tamar valley, so it might be worth going across Dartmoor to Tavistock and then down the river to Plymouth.
Mr Tom the tamar valley is a bit further west. You probably mean the Plym Valley (trail). I did part of it earlier this year when on the Devon Coast to Coast it provides a good downhill traffic free run into Plymouth from Dartmoor
