How do I actually follow this run once the AI writes it?

Paste the AI's reply into sweatcue. It structures the session into timed blocks with auto-starting rest timers and calls every set, rest and rep out loud, so you train hands-free instead of scrolling a chat window.

Easy aerobic base run

Q: What is the best ChatGPT prompt for a running workout like this?

Use the research-backed prompt on this page: "Write me a 45-minute easy base run. Almost all of it should be genuinely easy and conversational — heart-rate Zone 2 on a 5-zone watch — with an 8 to 10 minute easy warm-up jog, the main block at a relaxed aerobic effort…" Copy the full version with the button above — it wraps the request so ChatGPT, Claude or Gemini returns a clean, followable run you can run hands-free in sweatcue.

The run most runners skimp on — and the one that builds the engine. 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.

The prompt

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

Write me a 45-minute easy base run. Almost all of it should be genuinely easy and conversational — heart-rate Zone 2 on a 5-zone watch — with an 8 to 10 minute easy warm-up jog, the main block at a relaxed aerobic effort, and an easy finish. Add 4 relaxed 20-second strides near the end to keep my legs quick — these are smooth and fast, not sprints, with full recovery between. If I can't hold a conversation I'm going too hard. Give every block a duration and a target heart-rate zone.

Works with Claude, Gemini, Grok or any AI.

Why it's built this way

Successful distance runners spend roughly 80% of their training easy and conversational, and only about 20% hard — keeping easy days genuinely easy is what lets the hard days count. (On a 5-zone watch, that easy "Zone 2" is the aerobic zone below your first threshold.)
