DAILY SUGGESTED WORKOUTS

Gain a deeper understanding of your overall health, recovery and training performance through heart rate variability while you sleep, based on technology developed by Garmin's Firstbeat Analytics™ team.
Get ready for your next race with training tips, personalized daily suggested workouts and completion time predictions based on course details, weather and performance.
Free adaptive training plans include 5K, 10K and half-marathon programs, featuring guidance from expert coaches that adapt to you and your goals.
WRIST-BASED HEART RATE
When using a Running Dynamics Pod or HRM-Pro monitor, the Forerunner 955 watch measures crucial running metrics such as cadence, stride length, ground contact time and balance, and more.
Using new indicators such as HRV status, your recent exercise history and performance, get an easy insight into your overall effort — and whether you’re training productively, peaking or strained.
IMPROVED SLEEP MONITORING AND SLEEP SCORE
Understand how your body is recovering — and get ready for training — with our improved sleep monitoring feature. After waking up, you’ll receive a sleep score, as well as breakdown of your sleep stages, Pulse Ox3 and respiration, alongside detailed insights for improved sleep quality.
SAFETY AND TRACKING FEATURES
If you feel unsafe or if your watch senses that an incident occurred, Assistance and incident detection features1 send your location to emergency contacts. Incident detection is enabled by default for select activity profiles only.
Receive emails, texts and alerts right on your watch when paired with your Apple® or Android™ smartphone. You can even respond to texts if you have an Android phone.
MULTI-BAND GNSS SUPPORT
Access multiple global navigation satellite systems, and get access to multiple frequencies sent by navigation satellites for improved accuracy in areas where GNSS signals are reflected, weak or typically don't penetrate — giving you superior accuracy for how far and how fast you’ve run — even in challenging environments.
