Update: Mission Complete! After 7 hours in the saddle, we finally finished the 100k through the streets (and hills!) of London. Thank you so much to all those that sponsored me...overwhelmed by the support and thank you so much on behalf of Brain Tumour UK. 

-----------------------------------------------------------------------------------

So I am sure that right now you are laughing at the prospect of me attempting a 100km bike ride through the night!! (Dont worry, I dont blame you!) On June 9th, I will do my first ever challenge and will be putting all those spin classes to the test. 100km through the streets of London starting at 01.35am at Alexandra Palace - supporters are of course welcome :)

I will be raising money for Brain Tumour UK. As most of you know, my gorgeous brother died 18 months ago at the age of 35 from a brain tumour. The charity provides support, funding and research and rasies awareness of this horrible cancer.

BSKYB will match what I raise pound for pound up to £300, so please dig deep! I can hardly pull out once I have already started raising money so no going back once those first donations are made!

Thanks everyone, and wish me luck
