Gwen McEwan from Arncott strolled from her house in the town to Ambrosden, an overall of 7 miles.
The money raised is being contributed to Maggie’s Oxford, a cancer charity that provides assistance to anybody with the illness and their households.
She provided the £1,850 cheque to charity agent Kathy Talbot on Saturday (April 22).
Ms McEwan said: “I simply wish to let everybody understand where the money is going.
“I have this little dog called Pebbles and my grandson walked behind me just in case I had an accident”
The 81-year-old was influenced to raise money for charity after her other half died from cancer in 1995.
