She told the BBC that she tries to do something for the Thames Valley Air Ambulance every year. Usually, she holds coffee fundraisers, but the pandemic made that impossible this year. 

The centenarian initially just wanted to keep active, so she decided to start going for walks around the block. That gave her the idea: "While I was going round I thought what am I doing this for? I know. Thames Valley Air Ambulance. So that's how I started raising money for them."

Her granddaughter Katie told BerkshireLive that Ruth has always been fiercly determined: "When she puts her mind to something there is no stopping her.”

Ruth joined the ranks of British 100-year-olds walking for a good causes. In April, Captain Sir Tom Moore broke fundraising records by doing laps in his garden. The war veteran raised more than 33 million pounds ($43 million) for the National Health Service. 

Ruth and her granddaughter are now planning the next challenge and BrekshireLive reported that Ruth is thinking about swimming the British Channel or parachuting.
