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.

Threshold running between stations

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

Use the research-backed prompt on this page: "I'm an advanced Hyrox athlete. Write me a 35-minute threshold running session to help me hold pace between stations. Warm-up: 8 min easy jog to ~70% max HR plus 4x20s strides. Main set: 4x4 min at threshold (comfortably …" 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.

Hold goal pace at lactate threshold so station fatigue doesn't blow up your splits. 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).

I'm an advanced Hyrox athlete. Write me a 35-minute threshold running session to help me hold pace between stations. Warm-up: 8 min easy jog to ~70% max HR plus 4x20s strides. Main set: 4x4 min at threshold (comfortably hard, ~88-92% max HR or the fastest pace I could hold for ~60 min) with 60s easy jog recovery between reps. To mimic race fatigue, add 10 air-squats or 5 burpees immediately before reps 2, 3 and 4 so I start each run slightly compromised. Cooldown: 5 min easy jog. Give me pace/HR targets per rep, tell me how the pre-rep squats should shift my effort, and a simpler 3x4 min version if I'm under-recovered.

Works with Claude, Gemini, Grok or any AI.

Why it's built this way

Threshold (lactate-threshold / sweet-spot) intervals raise the pace you can sustain before fatigue accelerates, which is the quality that protects Hyrox run splits. Polarized-training research suggests most volume should stay easy with a smaller dose of hard work, so this single threshold session should sit inside an otherwise easy week. The pre-rep squat 'fatigue' tweak is a practical event-specific add-on, not a separately validated method.
