I am running the Manchester Marathon this Sunday the 27th of April for Narcolepsy UK. This is something close to my heart as Kim suffers from this condition and has done all her life. There are 30,000 people who suffer from this in the UK. Narcolepsy is a rare neurological condition that affects the brains ability to regulate the normal sleep wake cycle. This can lead to symptoms such as disturbed night time sleep, excessive day time sleepiness and cataplexy.
