Sisters Katie and Sophie Richards used their new Fitbits to spur them on in a fundraising challenge.
The girls reached their daily target of steps to raise £290 sponsorship for East Cheshire Hospice.
Their grandad Stephen Jones died of bowel cancer at the Hospice in 1998, aged 47, while late great grandad Gordon Oldfield, also from Macclesfield, was treated there as well.
Katie (9) and Sophie (8) warmed up for their month-long challenge by walking or running 5,000 steps a day for the first week.
Their target increased to 6,000 steps a day the following week and the last two weeks they covered 7,000 steps, raising the total to 10,000 for the last day.
Mum Emma Jones said: “We got them a Fit bit each as an incentive and they wanted to do something for charity since the Hospice is part of our family.
“The care it provided when my dad and grandad passed away was amazing and we wanted the girls to take the money to the Hospice so they could see what it does.”
“They’re proud of their achievement and want to thank everyone for their sponsorship.”
