For a change, I did my running training last weekend on the Baltic Sea. After two weeks of Siberian cold here in Helsinki, I reckoned that the ice cover on the Baltic Sea was thick enough to be safe for running. That's one of the few attractions of the Helsinki winter. If you want to get to know more about Helsinki and Finland, have a look at my sister's blog. Unfortunately, the blog is in German, but maybe I can convince her to make it bilingual: https://claudiashelsinki.wordpress.com/
