In July 2010 I will be departing on a 4 year solo bicycle expedition covering roughly 40,000 miles. My aim is to reach each of the 'four corners' of the old world (Europe, Asia and Africa).

Starting in my home village in the UK, my route will take me through several deserts (including the Sahara, twice), the Himalayas amongst other mountain ranges, the Arctic Circle twice (once during winter in far Eastern Siberia), the jungles of central Congo, the Middle East and much inbetween.

For more details of the expedition, please visit my website: www.charliewalkerexplore.co.uk

I am riding to raise money for the RNLI (www.rnli.org.uk) which provides an excellent 24-hour lifeboat rescue service in the UK and Ireland. The charity's 4,800 lifeguards are mostly volunteers and the charity relies on public donations to continue providing its invaluable service. Please give generously.
