This workout focused on 15-30 second efforts. While the longer duration can get away from pure speed, we focus on high-quality (L1 / L2) distance training between each interval to prevent accumulating fatigue.
5 x 3 min intervals building from high threshold (L3) to maximum effort on the last effort, 3-4 minute recovery between each. We choose safe roads, and a gradual grade with smooth pavement to ensure high speed.
The US Ski Team uses rollerski agility speed test to push the athlete outside their comfort zone so that zone can grow that much larger. When that ice patch surprises you in on skis, you're ready for it.
When planning training the emphasis should not be on what you will do, but rather how your body and mind will react to what you do. The goal is not to fulfill training, but to elicit a positive adaptation in your body and mind through training.,
