Disciplines

   * Navigation with topographical map and compass
   * Snowshoeing
   * Cross country skiing
   * Postholing (on foot without snowshoes)
   * Tyrolean traverse

Keep in mind that these disciplines can occur in any order, and you could have multiple sections in the course for each activity. You do not need to have done a tyrolean before to compete in this race; but it doesn't hurt to try it beforehand if you happen to get the opportunity.
