I am running the Cambridge Half Marathon this Sunday as part of 'Team Tom'.

My friend Debs lost her son Tom (who was 10) to a brain tumour in 2010, and since then she has set up Tom’s Trust which funds psychologists to help families deal with the mental health challenges that come with the loss of a child in these circumstances.

I have worked in this area academically and clinically. Such funds support my work/training and my ability to help such families in this situation.

Tom's Trust is a charity, started in Cambridge, which provides vital clinical psychology to children with brain tumours and this year we are running through history to change the future for those children.

I will be pounding the pavements this Sunday to raise money for vital clinical psychologists, who will support families following a child’s devastating diagnosis of a brain tumour. Tom's Trust are the UK’s only charity dedicated to this mission, with hundreds of families being helped every year thanks to you, our generous donors.

Tom's Trust children will each be representing a different landmark along the route. I will be thinking of them every step of the way while we change these children's lives.

Please give generously to support us, your help means we can change the future. Thank you.
