Duration: 40 minutes
Start your running journey by alternating short easy runs with walking breaks.
Start the session and follow the audio cues: the timers advance automatically, so you can keep your phone in your pocket. Run at an easy, conversational pace. If you cannot speak in full sentences, slow down.
Calistree gradually lengthens the running intervals from session to session. After about 3 weeks (9 sessions), move on to Phase 2.
