'Da ni fel chwiorydd wedi penderfynu mynd amdani i wneud her Tri Chopa Cymru ar gyfer achos sydd yn agos iawn i'n calonnau ni. Rydym ni eisiau codi ymwybyddiaeth o'r gwaith hanfodol mae'r elusen yn ei wneud a codi arian er mwyn galluogi'r gwaith barhau. As Sisters we've decided to attempt Welsh' Three Peaks Challenge and raise money for Parkinson's UK as it's a charity that's very close to our heart. We would like to raise awareness of the essential work that the charity does and raise money to ensure that this continues.
