There were 17 participants from various nations and all walks of life. For example we had a small wind turbine dealer from Ireland, a vicar, an electrician from Sellafield, an architecture student, a formula one racing mechanic, a GP, a dutch group therapist, a danish energy consultant, an american engineer, a catholic church worker from Uganda, etc.... Matthew cycled all the way from milton keynes to be there.
