Plis plis plis wnewch chi roi rhywbeth tuag at yr elusen arbennig yma. Mae'n cefnogi plant hefo cancr. Tydi rhedeg Marathon Eryri ddim yn dod yn agos at beth mae rhai o'r plant yma'n mynd drwy. Mi fyddwn ni'n gwerthfawrogi pob ceiniog a fe fydd o'n cadw'n coesau ni'n mynd drwy'r elltydd yn y marathon.

Please please please donate whatever you can to this very special charity. Running the Snowdonia Marathon won't come close to what some of these children go through. Any donation will be greatly appreciated and will ensure that our legs carry us up those hills.
