Protest

In October 2014, mountain bikers, walkers, horse riders, climbers and conservationists held a protest against Derbyshire County Council maintenance work on the byway that runs along Rushup Edge. They were upset at the insensitive nature of the work, the cost, the environmental impact and the apparent lack of consultation with them before works began. Derbyshire County Council halted the work to speak with protesters in December 2014.
