Ideas

What your AI builds for you

Memory.fit recommends nothing itself. These are words for your AI: copy one, paste it in, and your AI builds it in Memory.fit.

Plan training

  • Plan my next 4 weeks toward my next race in Memory.fit: a long run with climbing every weekend, one hill session and easy days in between.

  • Plan a back-to-back long weekend in Memory.fit: 3 hours on trails Saturday, 2 hours Sunday, with the climbing in the notes.

Race day

  • Write my race-day plan for my next race in Memory.fit: the two days before, race morning, gels per hour and a pacing note, with a checklist.

    You tick the checklist off in the app, from your race on You.

  • Plan what I eat at each aid station of my next race in Memory.fit, with the distance between them.

Fuel a session

  • Write a fueling plan in Memory.fit for Sunday's long run: gels, when to take them, and water.

    It shows inside that session on Plan.

  • Plan the fuel for my 5-hour trail run in Memory.fit: real food every 45 minutes and gels on the climbs.

Hydration

  • Sweat test: 72.4 kg before, 71.3 kg after a 60-minute run at 24 °C, drank 400 ml. Save it in Memory.fit.

    Memory.fit works out your sweat rate (You › Sweat and hydration).

  • Plan my water and electrolytes for Sunday's long run against my sweat rate, in that session's fuel plan.

Gym & strength

  • Add two short strength sessions a week to my plan in Memory.fit, away from my key sessions.

  • Plan a 30-minute strength session for runners in Memory.fit, twice a week: single-leg work, calves and core.

Recovery & sleep

  • I slept badly. Move today's hard session to tomorrow and make today easy.

  • Make next week a recovery week in Memory.fit: about half the hours, no hard sessions, and my sleep and HRV on Today.

Check-ins

  • Check Memory.fit for the run that just synced and tell me how it went against the plan.

  • Give me my morning brief from Memory.fit: what's new since you last checked, like last night's sleep, a weigh-in or a session that synced, and what's planned for today.

    If your AI can schedule tasks, ask it to run this every morning at 7.

Look back

  • Compare my planned and completed training over the last 4 weeks.

  • Look back at my last 8 weeks of running in Memory.fit: distance per week, my long runs and how my workouts went against the plan.

Your pages

Pages for trail runners

Layouts your AI builds on Today or Progress from your own data. Copy the prompt; Undo puts the old page back.

Progress page

Run focus

Running comes first: a marathon block, or fixing the run off the bike.

Example
Run distance this week
VO2max
Weekly run distance
Recent runs
Your race and goal
Training, Fueling, Body, Recovery, Strength
From your AI: reviews and insights
Read the prompt

“In Memory.fit, set up my Progress page for a run focus. At the top, two compact metrics side by side: my run distance this week and my latest VO2max with a 12-week sparkline. Then a featured bar chart of weekly run distance for the last 12 weeks, and a table of my runs from the last 14 days with date, session, duration, distance and average HR. Keep my race and goal and the pillars below, then the rest. Read Memory.fit's dashboard capabilities first.”

Today page

Fuel first

You want to get what you eat around training right, day after day.

Example
Next
Protein, 7-day average
Carbs, 7-day average
Energy in, last 14 days
Eaten vs your target
Still to come
Done today
Read the prompt

“In Memory.fit, arrange my Today page around fueling. Right under Next, put two compact metrics side by side: my 7-day average protein and my 7-day average carbs, each with a sparkline. Then a line chart of energy in per day for the last 14 days. Below them, keep what I've eaten against my target, what's still to come and what I've done today. Read Memory.fit's dashboard capabilities first, then tell me what you changed.”

Today page

Race week

The last seven days before a race, when every session and meal counts.

Example
Next
Days to race
Planned TSS, next 7 days
Race week
Eaten vs your target
Still to come
The week ahead
Done today
Read the prompt

“In Memory.fit, set up my Today page for race week. Right under Next, two compact metrics side by side: days to race and planned TSS for the next 7 days. Then a short race-week note in your own words with the key days (carb load, shake-out, race morning). Then what I've eaten against my target and what's still to come, a table of the next 7 days of sessions with date, time, session and duration, and what I've done today. Read Memory.fit's dashboard capabilities first, then tell me what you changed.”

Questions

Memory.fit for trail and ultra: good to know.

  • Yes. Give it the race's aid stations and the distance between them, and it writes the plan into Memory.fit, with a checklist you tick off in the app.

  • Do a sweat test: weigh yourself before and after a run and tell your AI what you drank. Memory.fit works out your sweat rate, and your AI plans hydration and electrolytes against it.

  • Yes. Structured sessions your AI plans go to Garmin, COROS, Wahoo and Suunto, and to intervals.icu, once you connect them in the Memory.fit app.

  • No. Your AI writes it. Memory.fit gives your AI your real data, keeps the plan your AI writes and shows it in the app with the AI's name on it. Any change can be undone.

  • One is enough: ChatGPT, Claude, Dots, Muse, Cue, Grok Bot, Gemini or any app that supports MCP connectors. Some need a paid plan from their maker.
