I have always wanted to run a half marathon, but have always been prevented from signing up by fear.

That changed when the news came that turned our family upside-down... again. Danny's cancer had broken through the chemo.

My wonderfully bright, unique, Star Wars-loving nephew had been diagnosed with leukaemia just before his 5th birthday, a day memorable primarily for the horrors of steroid-induced diabetes and incessant needle-pricks. Insulin instead of a birthday cake: very Raymond Carver.

Danny, along with his sidekick triplet brothers, Thomas, Lukas, and Aaron (who have also had their lives saved by doctors at the JR), have coped phenomenally well with the rollercoaster journey that the family has been on. Their parents are incredible: providing for triplet toddlers with a very sick child in hospital is not an easy task.

Almost three years later, just at the end of his treatment plan when all eyes were fixed on a chemo-free world and normality for the family, the leukaemia was found again: a silent, lethal, lurking evil.

Within a day, though, Danny had a new treatment plan, with an upcoming bone marrow transplant as an aim. On the next, this fearless family were at the beach, and then hosting a picnic in the park: this is what Danny wanted on his last weekend before what was to be expected to be a protracted hospital stay.

Danny and his family are strong beyond belief, but they could not be where they are today without the expertise, kindness and patience of the doctors and nurses, their specialist equipment, or the space for parents to stay with their children.

Sadly, Danny is not unique in this respect. There are too many children undergoing painful and lengthy treatments at hospitals across the county, country, and world; their experiences, though, can be so much improved by the amazing work that hospitals like OCH do.

Danny and his family - supported by OCH - have bravely taken each step as it comes, so I need to follow their lead. Anything that you can give would be really appreciated.
