I'm going to be stepping out on to a glass walkway at the Tottenham Hotspur Stadium, 46.8 metres above the football pitch and then finishing off with a controlled drop abseil.

It's all in support of Children's Air Ambulance.

The Childrens Air Ambulance is changing the face of paediatric care through the high speed transfer of critically ill children.

Right now, this free of charge service works alongside NHS transport teams to help fly paediatric patients to specialist treatment.

It is the first and only dedicated paediatric helicopter emergency transfer service in the country.

Please spare a few pennies to support this excellent cause if you can.
