Hi Daniel, sorry to hear of your loss last year and think that you have got a wonderful frame of mind to want to help PC generally.
Welcome to this forum, it is here to give help and support to those affected by PCa where it can. There are people on here that will suggest ways of helping further and help with ideas, I am sure, all forms of fundraising will ultimately help with research and hopefully allow those that have the worst forms of PCa to get better types of treatment and give longer quality of life.
Have you tried contacting your local PCa support group as there will be some organised fundraising events already planned and they will help you in yours as well.
Well done for taking positive steps to help others.
Keep posting on here to update us on your progress.
Best wishes, Chris/Woody
