Can AI prepare my marathon?

Partly

Partly. It calculates your paces and builds a plan, but it can't feel your legs.

What I do

I run on the road and a lot on trails. I built myself MARMOTT, a small AI coach for split times, cut-off times and aid stations. But my training plan comes from an app made by coaches, not from AI.

Section 02 · step by step

How you do it

  1. Step 2.1: Give your latest 10 km, your runs and the race date.
  2. Step 2.2: Ask for a week-by-week plan with paces.
  3. Step 2.3: Paste what you actually ran each week.
  4. Step 2.4: See a physio or a doctor for any lasting pain.
Plan BIf you get stuck

If the plan ignores an injury or your real volume, stop: give it that info before going on. Pain that lasts is for a physio, not for AI.

The prompt to copy
I'm training for a marathon on [date].
My latest 10 km: [time]. I run [3] times a week, on [Tuesday, Thursday, Sunday].
Make me a week-by-week plan, with paces in min/km for each session.
First, ask me the questions you need: injuries, current volume, elevation, time goal.

Section 03 · no sugar-coating

The limit

It can't feel your fatigue or your injury, and doesn't know if you slept badly. Follow the plan with your body, not against it.
