I have been getting into Nordic Skate skiing the last few years and have my first ski marathon coming up this winter. I am looking for a book, website, magazine, etc that can help me prepare. In particular I am looking for a resource to cover 1 or all of the following:
-workouts -nutrition -advanced technique -overall training program
Does any one have any good suggestions of a resource I can use to guide my training? Most books I have found so far are over 30 years old and therefore I'm not sure if they are still relevant.
