It's getting cold outside and the marathon season is not coming until another couple of months. However, if you enjoy running it is very unlikely that you will stop doing so during winter time. On the contrary, you will probably see it as a challenge and go running even more :)

But without further ado I want to recommend the following video to you that has been amazingly helpful to me.
