AI marathon plan :)

So, I dived in to ask AI to craft a plan for getting to NY marathon injury free, and manage my knee flare up. I haven’t been really mindful of my knee issue. When I feel good, I just keep running. Then I over do it, or forget that lunges are not my friend, and knee complains. Sigh…. I need to be more mindful going forward and limit my just-because longer runs.

Here’s AI’s suggestion with my comments

“Arrive healthy and finish feeling good” is the most New-York-appropriate mindset there is 🗽💙

Below is a clear, realistic roadmap to November, built around:

  • Saturday long runs
  • 1 spin day/week
  • Knee load management
  • Zero heroics, lots of consistency (love this!)

BIG PICTURE: NOVEMBER BACKWARD

NYC is unforgiving on the knees (bridges + camber), so the priority is durability over peak speed.

Phase 1: Calm the knee & rebuild tolerance

Now → end of May

Goal: Make symptoms disappear and stay gone

Phase 2: Marathon-prep foundation

June → mid-August

Goal: Strong aerobic base + gentle specificity

Phase 3: Marathon block

Mid-August → Race

Goal: Arrive confident, uninjured, and happy


PHASE 1 (Now → End of May)

4 runs/week | 30–38 miles

Weekly structure (example)

Monday – OFF or easy spin

  • Optional 30–45 min very easy

Tuesday – Easy run

  • 6–8 miles

Wednesday – Strength + spin

  • Spin 40–50 min (easy/moderate)
  • Knee-friendly strength

Thursday – Medium run

  • 8–10 miles steady

Friday – OFF

  • This protects Saturday

Saturday – Long run

  • Start where you are (10–12)
  • Build gradually to 14–16
  • Easy, flat, no workouts

Sunday – Easy run

  • 5–7 relaxed miles OR OFF if knee feels “heavy”

🔑 Rule: if the knee feels heavy after Saturday → Sunday is OFF.


PHASE 2 (June → Mid-August)

4–5 runs/week | 35–45 miles

What changes

  • Long runs reach 16–18 miles
  • Introduce light quality every 10–14 days
  • Possibly add a 5th run only if symptom-free

Long runs

  • Mostly easy
  • Occasionally:
    • Last 2–3 miles steady (not marathon pace yet)
  • No downhill focus yet

Quality examples

  • 3×10 min steady (comfortably hard)
  • 6×20 sec strides post-easy run

If heaviness returns → pull quality immediately.


PHASE 3 (Mid-August → NYC)

Peak: 40–50 miles max (only if knee allows)

Long runs (Saturday)

  • 18–20 miles max
  • 2–3 marathon-pace segments total, not continuous
  • Practice fueling, NYC shoes, pacing

Very important for NYC

  • Avoid excessive downhill training
  • Strength focus on:
    • Quads (controlled)
    • Glutes
    • Calves (bridges are calf killers)

SPINNING: WHERE IT LIVES

Once a week is perfect.

Best options:

  • Wednesday (as listed)
  • OR Monday if legs are tired

Keep it:

  • Seated
  • Light–moderate
  • Cadence > resistance

Spin replaces junk miles — it does not stack on top.


STRENGTH: KEEP IT BORING (love this!)

2×/week until August, then 1×/week maintenance.

Think:

  • Step-ups
  • RDLs
  • Bridges
  • Core

No ego lifting. No deep knee pain.


YOUR PERSONAL “STOPLIGHT” SYSTEM 🚦

🟢 Run

  • Knee feels normal later + next morning

🟡 Modify

  • Heavy feeling, pressure, stiffness → reduce frequency

🔴 Stop

  • Pain with stairs, sitting, or swelling

This system is how you arrive at NYC smiling.


REAL TALK ABOUT YOUR GOAL

A healthy 3:57 runner finishing NYC feeling good is a massive win.
If the knee stays calm, a PR-adjacent day can still happen — but we never chase it.

New York rewards patience and punishes bravado (love this!)


I find this plan reasonable given my previous training cycles. I will probably get coaching for the marathon block but phase 1 is what I want to focus on. MAKE KNEE BORING AGAIN is my goal! 🙂

Q: have you tried AI for workout/coaching plans?

One thought on “AI marathon plan :)

  1. A very good idea! AI can be very useful if we use it wisely.

    Your plan looks sensible – it includes all the important things and leaves out excessive speed training, which would probably get you injured in not time. Love the “make knee boring again” mantra!

    A running buddy of mine here in Cape Town trained for and successfully raced a half marathon on a ChatGPT plan. He showed it to me beforehand for feedback and it looked solid and reasonable.

    I’m so excited for you!! Have you heard back from the tour operator?
