I've raised £500 to help Guillem to visit London

Hi everyone WE need your HELP!
I would like to introduce you my Nephew Guillem, he lives in Perpignan - France and he will be 13 years old on April 23rd. He was diagnosed with Duchenne Muscular Dystrophy (DMD) which is a genetic disorder characterised by progressive muscle degeneration and weakness.
Since then all his family and friends have been helping him to fight this illness and make his live easier hence that a charity was created with the name “TOTS AMB GUILLEM (TOUS AVEC GUILLEM)” which means “ALL WITH GUILLEM”.
TOTS AMB GUILLEM (TOUS AVEC GUILLEM)
With the help of this charity Guillem and his friends have been able to participate in different events to show his support and raise funds to help Guillem to be closer to his dreams.
He has participated or being represented in different events, shows and sports activities.
One of his dreams is to visit London as he loves the City and everything related with England hence that we will be representing him this year in the Rightmove MK Marathon happening in early May.
Selene Lopez, Luis Flores, Julian Hidalgo, Gaby Salinas, David Puigdomenech and myself will be running and some others will be giving their support.
Our goal is to raise funds for Guillem to visit London and we have created an account in JustGiving where you can help Guillem to make his dream come true.

Thanks everyone for your help and support.
Kind regards,
