A daughter's promise to a dying father will be fulfilled when she competes in the London Marathon on Sunday.

Six years ago as Briony Craven-Russell's father lay dying of cancer, he held his daughter's hand and asked her to raise funds for the St Nicolas Hospice in Bury St Edmunds in Suffolk.

Briony says she does not really mind what times she makes. She just wants to finish to keep the promise, and then feast on the foods that have been forbidden during her training.
