Change Needed: SESSION FOCUS:
The focus of this session is on building your tolerance to intensities similar
to those during an Ironman triathlon. You will be working in the L3a-L3b
training zones. You should hope to see reduced HR drift within this zone as
you complete more of these sessions. From a physiological perspective, these
sessions help promote fat oxidation, and structural changes at a muscular
level, such as increased mitochondrial content and capillarization.

The road or indoor is preferable for this session. During the 35 min reps,
stay aero; focus on getting maximum speed for minimum effort.
