Raising funds for Solaputi Kids Camp

I am going to be running in the 2024 Tokyo marathon. To do so I am running for the charity - Solaputi Kids Camp. It is a wonderful charity. It allows for children with terminal diseases to go to a camp with their families and have all their medical needs taken care of while they’re there. This allows them to have quality time together. So much of their time is spent in hospitals. Any help would be greatly appreciated. Thank you.
