Finland: Paradise for cross-country skiing

At the moment, Finland is a paradise for cross-country skiing. Lots of snow and thousands of kilometers of cross-country ski-tracks (in the capital region almost 1000 km, most of which are easy to reach by public transport). A 13 km circular track starts just in front of my apartment at the old city district (Vanhakaupunki), and the picture for this post has been taken from this track. My sister Claudia maintains an excellent blog about Helsinki (https://claudiashelsinki.com) which mainly targets tourists and her last blog post featured cross-country skiing in Finland (and specifically in Helsinki). Her blog is very informative for everybody who wants to visit Finland and specifically Helsinki. However, Claudia writes in German (https://claudiashelsinki.com/2019/02/02/langlaufparadies-helsinki-und-fi...), but of course, there is Google Translate, which makes the information available, albeit it sometimes hurts: https://translate.google.com/translate?sl=de&tl=en&u=https%3A%2F%2Fclaud...
