CRY- cardiac risk in the young

My brother died 12 years ago from sudden adult death. I would like to try and help raise money towards other young people having tests,  to assist in preventing this happening to other families. 
On the 24th June me and my bestie Rach will be taking to London with lots of others to raise money for this very worthy cause. Walking near on 11km around many points of London. So please dig deep to show your support. 
Thank you
