I don’t often pester friends for good causes, but Sven Sorensen, my wonderful dentist in Haywards Heath, West Sussex has been extremely generous with my latest challenge – and I didn’t even ask him to sponsor me!

The last time I asked for sponsorship was when I was still working as a reporter at TVS in 1982 when I rather foolishly volunteered to run the Maidstone Marathon, and even the great Franz Klammer donated £50 (a tidy sum back then!). Now, in January, with my TV producer daughter Sam and her partner Nick I am taking on the Alpine Challenge, a charity event challenging our team to clock up 150km+ of GPS-tracked skiing over two non-stop days across the 15 resorts of the massive Portes du Soleil ski area in France and Switzerland, navigating to as many checkpoints as possible across each of the 15 ski resorts. The team that successfully visits the most checkpoints and clocks up the most kms will win!

We are raising funds for the youth charity Snow-Camp, which uses a unique combination of skiing, snowboarding and life-skills programmes to support inner-city youngsters. Through the combination of snowsports and life-skills, their programmes enable young people to grow in confidence and with self-esteem, develop as individuals and make positive choices in their lives. Thank you Sven! You can inflict as many fillings as you like on me from now on!
