Last year and the year before I cycled a stage of Le Tour de France for charity; in the Pyrenees in 2005 and the Alps in 2006. Thanks to everyone's generosity I raised over £3,500 ($7,000) for Medecins Sans Frontieres. Despite last year's stage nearly seeing me off, this year I've raised the bar and entered "La Marmotte", amongst the toughest one-day cycling events in the world. While only 173km long it has over 5,000m (16,400 feet) of total climbing. The route basically fits in all the highest mountain passes in the area for a scenic route of torture through the French Alps. Starting with Col du Glandon/Croix de Fer (1,924m), then the Col du Telegraphe (1,566m), followed by the mighty Col du Galibier (2,647m) and a finish up the legendary 21 hairpin climb of Alpe d'Huez (1,850m).

Preparation this year has had the added challenge of the arrival of my daughter in January, when I normally start training. Giving up puddings to lose weight over the past 5 months has been much easier to cope with than giving up sleep.

So on Saturday 7th July as the pros start Le Tour de France pedaling past London's landmarks at over 60 km/h, spare a thought, pound or dollar for the complete amateur climbing the Alps at a painful 6 km/h that same day.

I am raising money for Medecins Sans Frontieres (Doctors without borders). Paula (my wife) & I have both been impressed with MSF's work and courage during our times working in Malawi and Pakistan respectively. Donating through this site is simple, fast and totally secure. It is also the most efficient way to sponsor me: Medecins Sans Frontieres UK will receive your money faster and, if you are a UK taxpayer, an extra 28% in tax will be added to your gift at no cost to you. The cost of this trip will be covered by myself so all money donated will go to helping the work of Medecins Sans Frontieres.

Many thanks for your support.
