Pacing: Run Coach & Tracker

Design your run in ChatGPT, then go run it. Pacing takes the workout or training plan you put together in conversation and turns it into a real, coached session on your phone, so nothing gets lost copying splits into a notes app. Ask for whatever you're training for: a 6x800m interval session, an easy long run, a threshold tempo, or a full multi-week build from couch-to-5K to marathon. When it's ready, Pacing hands it off with a card, code, deep link, or QR scan. Open it in the Pacing mobile app and it becomes a live workout, with real-time voice cues that talk you through every interval, nudge you when your pace drifts, and give you a heads-up before each change. Prefer to train by feel? Turn on heart-rate zone guidance, including live heart rate from AirPods Pro 3 on supported iOS devices. Review the session, adjust the paces, save it, schedule it, or just hit start. No GPS watch needed.
