Vo2 Max intervals are short to moderate length intervals performed at a high level of power; power you could sustain for maybe a 8-16 minutes max effort (read: pain cave). We’ll break this effort up into much smaller chunks of 2-4 minutes, with relatively short rests of equal duration, to make the effort more manageable and allow you to get between 15-30 minutes worth on work at your Vo2 Max power. HR will lag behind on these efforts since they are short, but will likely climb to a very high level, a little short of max HR, by the end of the last few intervals. RPE on these intervals is a 9 on the 1-10 scale. I like to do these on the trainer (controlled environment) or outside as hill repeats (6-8% grade) to allow for steady power output.
Vo2 Max intervals allow you to train above your race day steady state effort and get you more comfortable with digging deep to drop a competitor, bridge a gap, or get over a steep climb with power and then recover without blowing yourself up.
