SESSION FOCUS:
The focus of this session is to spend as much time as possible at and above
~90% of your VO2max. The priority is on maintaining high power/pace during the
work intervals. These sessions are highly stressful but great for generating
adaptations that will improve your oxygen-carrying capacity and therefore top-
end aerobic capacity. For long-distance triathletes, these sessions can also
serve as an effective precursor to longer interval sessions.
