This March my Mum and I are running the London Landmarks Half Marathon to raise money for The Addison's Disease Self-Help Group. This will be my Mum's first half marathon following her smashing two 10k races last year. I have previous with this distance and an inability to listen to my own knees. It should be fun.

Addison's is a rare, endocrine condition where the adrenal glands cease to produce certain hormones essential for life. Continuous, daily treatment with replacement steroid hormones is required and medication must be taken several times a day at carefully timed intervals. With the right balance of daily medication, and good medical support, most people can lead long and active lives. However, they are also likely to need emergency medical treatment to prevent a near-death adrenal crisis at some stage.

The Addison’s Disease Self-Help Group (ADSHG) is a registered charity in England & Wales (number 1179825) who work to support people with adrenal failure and their families and to raise medical awareness of this rare, endocrine condition. The group publishes a quarterly newsletter, runs an electronic discussion group, holds an annual medical lecture, regional seminars and social meetings. The ADSHG has provided my Dad, who has Addison's, and our family with support and guidance for over twenty years.

Any small donation you can make will be great for the charity and will also help motivate me and my Mum during our respective training runs. Thank you for your time and generosity.
