I've raised £600 to Shetland Kidney Patients association

Hello,
I am planning on doing the London 2 Brighton walk for charity.
It's 100km walk for about 22-25 hours!
I am going to be raising money for Shetland kidney patients association, which help families and people struggling with kidney related illnesses. Such as cancer/dyalasis/transplants.
This charity is close to my heart as my mother died of kidney cancer in 2019 and my dad is currently on dyalasis and has been for nearly 5 years. They were very good, helpful and supportive with both my parents when/if they needed it and I would just like to give something back to help as they don't get alot of funding.
Any amout you want to donate would be amazing.
I appreciate your support, thank you.
