100k running and 100k walking in January

Over Christmas my nan who has been suffering with dementia for years was taken into a care home as my grandad who himself is in his 80's couldn't cope anymore. This is the first time in 60 odd years of marriage they have been apart, even when my grandad was deployed in the army, they found the local phone box number so he could arrange to call there and stay in touch.
With this horrible virus he can't visit her or see her, which is hard for both of them to understand, but the care home and carers are looking after both of them. 
I wanna try and raise a bit of money to help with this horrible disease, I know we're in hard times, so if you can donate please do, anything will be something ☺
