I have a question for the gurus of letsrun.
Early in the season more general endurance workouts are the focus but as the competition season gets closer and into the competition season endurance workouts should become more specific to the demands of the race and for the 1500 become primarily at 3k-5k paces.
What I'm stuck on is how to structure these workouts for the most benefit.
1. Short intervals, 200m-800m, with short recovery, 30-90 sec.
The advantage I see of doing this is that the heart rate is kept high throughout and would almost be kind of like a fartlek.
2. Long intervals, 600-1600m, with longer recovery, 2 min - 5 min.
The advantage of this is that it will help the runner develop more resistance at that pace. However, will such long recoveries hinder the aerobic development?
