Today our marchers began the 11 mile route from Cardiff to Newport.
The crowd gathered in Gorsedd Gardens, opposite Cardiff's great City Hall, whose postcode is CF10 3ND - is it a coincidence that CND appears in this very first postcode?
Frankie Armstrong and the amazing Cor Cochion Caerdydd Womens Choir brought their golden voices to Gorsedd Gardens this morning to start proceedings off.
Today's march is expected to take around five and a half hours to reach their destination in Newport, The Riverfront in Kingsway.
Talks were given by original Greenham Women, including Ann Pettitt, Jill Evans and Sue Lent will be digitally broadcast from 6.30-8.30 this evening.
