I'll be running the Stockholm Marathon on 3 June to raise money for the Haematology Unit at University Hospital of Wales, Cardiff, whose care for my wonderful and much missed Mam remains deeply appreciated.

The Haematology Unit became a second home to Gaynor, and the meticulous care and friendly support she received undoubtedly contributed to her remarkable quality of life living with blood cancer for over two and half years. In recognition of the excellent care and treatment provided by all staff throughout Gaynor's illness, I want to raise donations in memory of a beautiful Mam and wife, to assist others facing a similar experience.

It would have been Gaynor's birthday on 4 June, so the Stockholm Marathon seemed as good an opportunity as any to get fit and raise some funds! I've been training for more than three months and feel just about ready...

Ar 3 Mehefin, byddaf yn rhedeg Marathon Stockholm er mwyn codi arian ar gyfer Uned Haematoleg Ysbyty Athrofaol Cymru, Caerdydd. Rydym ni fel teulu yn parhau i fod yn hynod werthfawrogol iddynt am y gofal a roddasant i Fam hyfryd. Mae yna golled enfawr ar ei hôl.

Roedd yr Uned Haematoleg fel ail gartref i Gaynor, ac, heb os, cyfranodd y gofal diwyd a'r gefnogaeth gyfeillgar a gafodd at ansawdd bywyd rhyfeddol tra'n byw gyda chancr y gwaed am ddwy flynedd a hanner. I gydnabod y gofal a'r driniaeth ragorol a ddarparwyd gan yr holl staff drwy gydol salwch Gaynor, hoffwn godi arian er cof am Fam a gwraig hyfryd, i gefnogi eraill sy'n wynebu profiad tebyg.

Byddai wedi bod yn benblwydd ar Gaynor ar 4 Mehefin, felly roedd Marathon Stockholm yn ymddangos fel cyfle perffaith i ddod yn heini a chodi arian! Dwi wedi bod yn hyfforddi'n drylwyr ers dros tri mis, a dwi'n credu mod i bron yn barod...
