We are now entering a phase of higher intensity and Vo2Max building workouts. On tap this week; We try a new longer duration 6-minute L4 interval day. This time of year we want to focus on quality over quality during these intensity weeks. We also include one speed training day and a double-pole centric threshold interval session. For the Junior and Elite plans we will cut back on long over-distance training for the next two weeks while on the Masters side we continue with longer weekend sessions to continue our preparation for longer marathon races.
