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
