Every Tuesday in September will be intensity night, with a session focused on training at or near race speed. Every Wednesday in September will be strength night, with a session focused on general and specific strength training.
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.
While running hill climb tests of 12-20 minutes are a good way to assess VO2max (high-end) fitness throughout a preparation period and career, a threshold test can be used as a way of seeing work efficiency from stage to stage throughout the entire test.
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.
