Recently I have seen some training programs of some
top marathon runners and oftentimes training runs
are classified simply as “easy” or “moderate” or “hard”.
This made me wonder about the meaning of “easy” or “slow”.
There is “regeneration” pace which can probably be very very
slow since the sole purpose is to speed up recovery from
other training. But the meaning of “slow” is more vague to me.
Presuming that anything below aerobic threshold (AeT) can be
considered slow, there’s different degrees of slow. Let’s say
that AeT is at 82% of HRmax and say you have a 3hr “easy”
training session. You can now do this 3hr session at
81% of HRmax or at 70% of HRmax. While in theory both
intensity would be “easy” or “slow”, in my experience they
would have different feel and very different fatigue levels
after the training.
So, how do we distinguish between different levels of “slow”?
In running, there’s no point going slower than some pace, but
I am not sure if this is true for mountain running or
