Diolch am fy nghefnogi gyda'r her yma o gerdded 26 milltir o gwmpas arfordir Gwyr. O fod wedi bod trwy cancr fy hun ddwywaith yn y blynyddoedd dwetha, dwi wedi penderfynu fy mod am osod heriau rheolaidd i fy hun a cheisio casglu arian at achosion da yn gyson a dyma fe am eleni!!! Felly mae Heledd, fy chwaer, a finne am gerdded 26.2milltir ar y 9fed o Orffennaf! (Gobeithio!) Croesi bysedd am ddiwrnod sych.
