The plan

Run the first 10k easy, the second 10k at threshold pace, around 4:15/k. Total
time somewhere around 45 minutes. Treat it like a workout, not a race.

The first 10k

Easy, smooth, feeling strong. Mile three a group of three runners passed me,
steady, looking like they knew what they were doing. I sat about fifty metres
back, relaxed, watching them work.

The middle

By the second 10k marker the threshold pace felt good, which is the signal
that you can go faster, which is the signal that a race is starting, whether
you meant it or not. I moved up and caught the trio at 12k.

They were running 4:10. I sat in for two kilometres at that pace, which was
faster than the plan, which was fine.

The moment

At 14k I did not feel terrible. I felt good. The other runners were still
there. The finish line was six kilometres away and the body was saying yes.

That is when you move.

The last six kilometres

Five kilometres faster than planned, at 3:55, the legs still responding. The
three runners stayed close for five kilometres and then fell back one by one.

The last kilometre was alone, which is where you learn if the pace was real or
if the crowd was carrying you.

The pace was real.

The time

39 minutes and 12 seconds for 20 kilometres, 3:56 per kilometre, which is a
marathon pace of about 2:44, which means the training worked and the body does
what you ask if you ask it correctly.

The plan that survived

The plan to run the first 10k easy did not survive the starting line. The plan
to run threshold pace did, even though the pace got faster. The part of the
plan that matters, the weekly pattern and the monthly cycle, survived
everything.

The plan is a skeleton. The race is the body it hangs on.

The signals

You have enough rest when

• The first kilometre feels smooth, not like wading through water
• Your resting heart rate is normal for you
• You want to run, not like an obligation but like a thing you enjoy

You need more rest when

1. The first kilometre still feels heavy at the end of the first week
2. Your resting heart rate is elevated by ten or more beats
3. You do not want to run; you are doing it because it is on the plan

The third one is the most honest. The body lies about everything except
desire.

The cycles

A four-week cycle, hard-hard-hard-easy, is the pattern most runners use. The
fourth week, the easy one, is where the adaptation actually happens. The
hard weeks build the stimulus. The easy week lets it take.

What you cannot know in advance

How much hard is too much for your body in your season. You can only know by
trying and by paying attention.

The runner who never risks fatigue never finds their limit. The runner who
finds their limit every month is broken by June.

The decision that matters

When do you ignore the plan and rest anyway?

• If you are sick or injured, always rest
• If you are emotionally exhausted, always rest; running is a body activity
  done by a mind and the mind comes first
• If the body is clearly asking, almost always rest; the body is usually right

The only time the plan wins is when the doubt is small and the plan is recent
and the workout is short.

The week I learned this

Weeks four through six of a nine-week training cycle, I was running on empty.
The resting heart rate climbed to 58 from 52. I ignored it. Week seven I ran
the hardest workout on schedule and it felt flat. Weeks eight and nine I ran
well but not great.

The next cycle I took an extra easy week when the heart rate told me to. The
hardest workout felt the best. Everything that came after was faster.

Rest is not a gift you give yourself. Rest is a part of the training you
do.

The first kilometre

The legs feel heavy. Everything feels wrong. This is normal and it passes.

The mistake is stopping.

The middle

The discomfort is consistent. You are not getting better and not getting
worse. The pace feels achievable if you do not think too hard about how much
is left.

The trick here is anchoring: pick a runner ahead, catch them, move to the
next one. Do not think about the finish line. Think about the next person.

The moment where it breaks

Usually around the 20k mark in a marathon, or the 3k mark in a 5k. The
accumulation of effort tips into something harder and the body tells the mind
it is done.

The mind has one move here: it is a feeling, not a fact. Feelings pass.
Run through it, do not stop in it. The 200 metres of discomfort become
200 metres of accomplishment if you do not pause.

The finish

The relief is real. The accomplishment is real. The sense that the body
betrayed you halfway through is also real, and also false.

What the body did was run a race. What the mind did was convince itself it
could not, during the moment it mattered most.

What changed in training

The only way to know you can run at the edge is to run at the edge in
training. One hard workout per week is where the mind learns what it can take
and the body learns what comes next after “I cannot.”

The workout that changes everything is the one where you hit the wall in a
safe place, and find out the wall is made of paper.

Recovery pace

Easy runs between harder workouts, keeping the blood moving while the legs
rest.

Five minutes per kilometre and slower. Talk easily. The point is low stress and
high volume. Do not go faster because you feel good.

Long run pace

The long run teaches the body to burn fat and to run for hours. It is not
fast.

Only five to fifteen seconds faster than recovery pace. A long run and a
recovery run are the same pace on different days.

Threshold pace

The fastest pace you can hold as a conversation dies, usually around 4:15
per kilometre. The first workout where speed matters.

This is the pace of a 10k race, and training at threshold is how you move
that pace faster.

Interval pace

Short, hard repeats at the pace of a 5k race, recovered with easy jog, done
when the legs are fresh.

Three kilometres at 3:50, recovering with a kilometre at 6:00, repeated six
times. The body learns to tolerate lactic acid and the mind learns that it is
not fatal.

Race pace

The pace of the distance you are training for. Everything else is either
building to this or recovering from it.

For a marathon, about 4:30 per kilometre. For a 5k, 3:50. The week has one
workout at race pace, once the base is built.

The training week

One long run at long-run pace, one workout at threshold or interval pace, and
three or four days at recovery pace is the week that works for most of the
season.

Speed is specificity: the body does what you ask. Ask it to run fast in a
workout and it learns. Ask it to run fast in easy runs and it learns
that too, and then the workout is already hard before it starts.

The month at a glance

Base building is simple: easy runs stay easy, the long run grows, and
speed comes later. The only number that matters is the long run and it
climbed from eight to twelve in a month.
