Workout Writer vs RunBuilder

Type a running or cycling workout in plain English, then send the structured session to Apple Watch, Garmin Connect or Intervals.icu. Got a session from a coach, club, training plan or group chat? Instead of rebuilding every warmup, interval, recovery and target in a watch app, paste it into Workout Writer - or type your own. The structured workout forms as you write, ready to send to your watch. For example: 10 min easy 6 x 800m at threshold, 90 sec easy 2 km cool down Workout Writer turns that into a watch-ready session in seconds. What you can do: • Write workouts naturally Create structured running and cycling sessions from plain text. Warmups, intervals, repeats, recoveries and cooldowns take shape as you type. • Set your targets Use pace, heart rate, power or cadence, plus reusable effort tags such as Easy, Tempo and Threshold. • Send to Apple Watch, Garmin Connect or Intervals.icu Schedule a workout for a specific date or keep it ready to use whenever you need it. Intervals.icu can sync workouts onward to Garmin Connect, COROS, Suunto, Wahoo and Zwift. • Plan your training See upcoming sessions in Schedule and check the weather before heading out. • Reuse and share workouts Edit saved sessions and share them by link, QR code, image or text. Perfect for sending an interval workout to your run club, sharing a coach's session, or giving training partners the same structure with effort tags that adapt to each athlete. • Use Apple Shortcuts Create and schedule workouts from text, list saved workouts and tags, or check what is planned for a day. • Work with compatible AI agents on Mac Use the new MCP and CLI integration to connect compatible AI agents to Workout Writer on macOS. • Generate workout ideas Use Workout Writer AI when you want a starting point for a run or ride, then edit the generated session before sending it to your watch.
