Can Dave’s knees hold out?

At the age of 52, I have been entered (by my wife- as a surprise!) into the Cardiff half marathon. That gives me 3 weeks to prepare! I am raising money for a beautiful little girl, named Lexi. Her parents were close friends of ours through school. Lexi suffers with Migrating Partial Epilepsy of Infancy, a very rare and very severe form of epilepsy, and hugely life debilitating. Lexi will never walk, talk, or eat of her own accord,and requires 24 / 7 care for the remainder of her life. Lexi will need her own Wheelchair adaptive vehicle,will need to have the house adapted for her very special needs, and will need around the clock care . I am asking for your help in sponsoring me and enabling me to raise money to help them adapt their house for Lexi's needs.
