My Mum, Lynne, who has to tag along with me as a 'responsible' adult is a Director at CAAS.  I know how much work she and the team she works with do to support families like ours.  They are an amazing charity who do a huge amount of work on a small budget.  I wanted a challenge that seemed fun, and it made sense to do it for a cause that means a lot to my family and I.
