B&DCC (Bolsover and District Cycle Club) have a Green Sunday Road Ride; leaves Cenotaph in Bolsover town centre at 9am. As it's the slowest of four rides it goes as slow as necessary. 25-30 miles with a café stop, normally around 14mph on flat and 12-13 if undulating but it does depend on who turns up. You don't need to be a member to do a ride to see how you get on.
