What 80/20 Running is about

80/20 Running, by Matt Fitzgerald, is built on one rule: roughly 80 percent of your weekly running at low intensity and 20 percent at moderate-to-hard intensity. "Low" means easy effort — conversational pace, roughly heart-rate zones 1-2, below about 75 percent of max heart rate. "Hard" covers tempo, intervals, hills, and races — zones 3-5. The science is about training distribution: most of the stimulus to build your aerobic engine comes from easy miles, done often enough to add up. A typical week is mostly easy base runs plus one or two quality sessions — a tempo, an interval session, a long run — with rest days in between. Plans progress phase by phase: base, build, peak, then taper before a race. Days can be time-based or distance-based, and every session carries a pace or heart-rate target.

Act as an endurance coach in Matt Fitzgerald's style, based on the 80/20 Running method.
Build me a weekly endurance plan. Follow these signature rules exactly: around 80 percent
of my weekly running must be at low intensity — easy, conversational effort, roughly
heart-rate zones 1-2, below about 75 percent of my max heart rate; the remaining 20
percent at moderate-to-hard intensity — zones 3-5, tempo runs, interval sessions, hills,
or races; build the week mostly from easy base runs plus one or two quality sessions (a
tempo, an interval session, a long run); structure the plan phase by phase — base, build,
peak, and taper if I have a race date; give every session a time or distance target plus a
pace or heart-rate target; include full rest or recovery days; progress week by week
without spike weeks.

My details: my max heart rate is approximately [NUMBER] BPM or I train by [EFFORT / PACE],
I run [DAYS PER WEEK I CAN RUN], my current weekly volume is [MILES/KM PER WEEK], my race
goal is [E.G. 10K in 12 WEEKS / MAINTENANCE], and I run [ROADS / TRAILS / TRACK / MIXED].

Write the full plan now:
- A phase-by-phase plan: base, build, peak, and taper for my goal, with the number of
  weeks in each phase.
- For every week a training table with columns: WORKOUT | DURATION/DISTANCE |
  INTENSITY/PACE | NOTES, laid out as a weekly schedule covering all [DAYS PER WEEK]
  sessions.
- Mark every session as easy (zone 1-2) or quality (zone 3-5) so the 80/20 split is
  visible at a glance, and state the running-total split for the week.
- The 80/20 rule in two sentences max: what counts as easy, what counts as hard.
- End your answer with exactly 4 bullet takeaways titled "Next session: 3 things to remember".
