I always loved swimming in open water. There is something about swimming in cold water that gives it a meditative quality I love.

I pledge to swim every day in open water at Lake Constance until january 1st 2011 to raise money for charity water.

I live in Konstanz and I feel priviliged to be able to swim every single day in such an amazing natural environment while so many people are struggling to find clean water.

I will be reporting about my progress on twitter (@francis_dierick) and at http://www.coldwaterswimming.com. I'm using the quantt hashtag syntax to describe my daily efforts, so on my twitter profile you will see things like #swim:20min
