<p>This summer&nbsp;I'm hoping to raise some money for&nbsp;MacMillan Cancer Support who do great work helping people afected by cancer</p> <p>On the evening of 21st August I'll be setting off on the epic Paris-Brest-Paris&nbsp;<a href="http://www.paris-brest-paris.org/pbp2011/index2.php?lang=en&amp;cat=accueil&amp;page=edito">http://www.paris-brest-paris.org/pbp2011/index2.php?lang=en&amp;cat=accueil&amp;page=edito</a>&nbsp;</p> <p>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.</p>
