Intermediate · 25–39 · 4-week plan · 3 days a week

Four weeks of mostly-easy running that builds to a continuous 5k. Below is a research-backed prompt for ChatGPT, Claude or Gemini, copy it, paste the reply into sweatcue, and run the whole run hands-free.

This is how sweatcue structures the session once you paste it in, timed blocks with auto-starting rest and spoken cues. Figures are read from the prompt itself.

The prompt

Copy the complete prompt (it wraps the request below so the AI returns a clean, runnable session).

Build me a 4-week plan to run a continuous 5k, training 3 days a week. Keep most of the running easy and conversational (heart-rate Zone 2), gradually increasing the time spent running versus walking each week, with one slightly faster session a week and a rest or cross-training day. For each training day list the week, and the run as a duration with a target effort or heart-rate zone. Include the rest days.
Works with Claude, Gemini, Grok or any AI.

Why it's built this way

Building up to a continuous 5k works best by keeping most running easy and conversational and gradually increasing the running time week to week, with only a small amount of faster work, the mostly-easy distribution endurance training is built on.

Who this plan is for

Built with one person in mind: 30s, run a few times a week, training toward a strong 5k to half-marathon.

  • You’re an intermediate-level trainer and you want a bigger aerobic engine.
  • You have access to the kit it calls for: just you (a watch helps).
  • You want a structured, progressing plan rather than a one-off session.

Who should adapt or skip it

  • It’s low-risk for healthy adults. Scale the loads and reps to your own level rather than copying the top of every range on day one.
  • As with any new routine, check with a clinician first if you have a medical condition, are injured, pregnant, or returning from a long lay-off. This is general information, not medical advice.

What a 2-week plan looks like

This is a multi-week plan that progresses as you go, the AI builds the later weeks harder. Here’s the rhythm of the opening fortnight, at about 3 sessions a week:

Week 2●·●·●··

● This session· Easy cross-training or rest

Keep session days apart where you can, and adjust for how you feel. When you paste the AI’s reply into sweatcue, each session runs hands-free with spoken cues and timers.

Run it hands-free in sweatcue

sweatcue is an AI workout dashboard: paste the AI's reply and it runs the whole session on screen and out loud, auto timers, spoken cues for every set, rest and rep, and your live numbers. The AI writes it; sweatcue runs it.
