On Saturday 13th September I will be participating in the 25km Thames Bridges Trek to raise money for the Redthread children's charity. Redthread works with children and young people affected by violence, mental and physical health issues, grooming and exploitation. It does this through supporting them in hospitals, training NHS staff and other professionals to identify and support those at risk, and campaigning to improve services and change policy. Last year, the charity supported over 1,200 young people to lead healthy, safe and happy lives.
