Building upon the previous Sub-Threshold XX session, this time, we are decreasing the time between surges and increasing the number of surges. By challenging your ability to process lactate at near-threshold power, you will increase your exhaustion time and endurance.

All this is achieved with a 30min steady state effort that dips briefly into the realms of VO2max.
