This summer I'm hoping to raise some money for MacMillan Cancer Support who do great work helping people afected by cancer

On the evening of 21st August I'll be setting off on the epic Paris-Brest-Paris http://www.paris-brest-paris.org/pbp2011/index2.php?lang=en&cat=accueil&page=edito 

I'll attempt to ride from Paris to Brest and back in a maximum of 90hours, a total of 1200km/750miles. This is a very tough event which is at the very edge of my ability as a cyclist. The main problem is likely to be lack of sleep, covering 200miles each day means there will not be a lot of time to sleep. After 4 days this is likely to become a serious problem.
