While there are fewer wipeouts in an average day of Nordic skiing than there are in Alpine, a cross country skier will occasionally strain a muscle or otherwise have to spend a day or two relaxing at the lodge. Then, of course, there are those summer days when a skier sits back and dreams of snow. For both of these occasions, a book about cross country skiing—on where to do it and how to improve their skills and conditioning for the sport—would come in handy.
