Shape is a training planner for runners, cyclists and triathletes. It pulls in your workouts and recovery data, shows how your training is going, and lets you plan ahead in the calendar or with Claude and ChatGPT. TODAY See your readiness each morning, from your sleep, resting heart rate and HRV. Training load balance, fitness, fatigue and form, all including what you've planned, so a heavy week shows up before you're overtraining. CLAUDE AND CHATGPT Shape works as an MCP connector. Ask how your last block went, why a run felt hard, or to plan the next four weeks. Claude and ChatGPT read your workouts, sleep and HRV, and write the plan straight into your calendar, and it syncs to your devices. CALENDAR Every sport in one calendar, planned and done, with your weekly load on top. Plan on your phone or the web, and sync your plan to Google or Apple Calendar. BUILD WORKOUTS BY TYPING Type "5x1km at threshold, 2 min easy" and Shape turns it into structured steps, ready for your watch. WATCHES AND APPS Garmin, Apple Watch and Apple Health, Wahoo, Polar and Intervals.icu. Completed workouts, sleep and HRV sync in automatically. Planned workouts go to your Apple Watch, Garmin or Wahoo. WORKOUTS Each run and ride shows the route on a map, charts for pace, heart rate, power and cadence, your laps and time in zones, whichever watch or app recorded it. WHY I BUILT IT I'm Samuel. I ran the Stockholm half marathon with a cold, ended up with pneumonia, and spent months working back from 15-minute walks. I built Shape to plan that comeback and now use it every day to help me train smarter. Terms of Use: https://shapecalendar.com/terms Privacy Policy: https://shapecalendar.com/privacy
