<p>Finally, I'm getting off my arse and doing something good - namely getting <em>back</em> on my arse, but on a relatively uncomfortable saddle rather than a nice soft sofa, for <em>54 miles of gruelling cross-country, trans-alpine extreme cycling</em>. &nbsp;OK, so it's London to Brighton, by road, and there aren't any alps, but there are the South Downs, which are pretty close I think you'll agree. &nbsp;And those pretty little Sussex villages can be more dangerous than you'd think...</p> <p>&nbsp;</p> <p>So, really, I need all the encouragement I can get - please dig deep and donate now.</p>
