Last Sunday I ran through St Kilda in my underwear.

Possibly I should add more details to this story!

Running through St Kilda in my underwear was for the Cupids Undie Run which is a fundraiser for the Children’s Tumour Foundation of Australia. This foundation supports families impacted by Neurofibromatosis (NF). This is the disorder my eldest son has – he has NF2 which is the rarer form.

The fundraiser raises much needed funds for treatment, family support and research.

Many people have asked if I was embarrassed to run in my undies or said how brave I was. What they don’t understand is that as a parent you feel helpless when you can’t help or fix what is wrong with your child. So the thing I can do is help with funds. And if embarrassing myself for a short time helps raise funds then I am in. This is the second year I have done this and I will continue every year until a cure is found.

Bring on the embarrassment – I am going bigger and better every year. Because I would do anything to take away the stress and pain my beautiful boy suffers.
