When using a Running Dynamics Pod or HRM-Pro monitor, the Forerunner 255 watch measures crucial running metrics such as cadence, stride length, ground contact time and balance, and more — while comparing to others in the Garmin Connect app.
VISUAL RACE PREDICTOR
Based on your running history and overall fitness level, get an estimate of what your pace could be for a 5K, 10K — or even a marathon. Plus, trend data highlights your training’s impact over time
WRIST-BASED HEART RATE
The watch constantly samples your heart rate with our latest-generation heart rate sensor and will alert you if it stays too high or too low while you’re at rest. It also helps gauge how hard you work during activities — even while swimming.
BODY BATTERY ENERGY MONITORING
Track your body’s energy levels so you can find the best times for activity and rest.
PULSE OX SENSOR
This wrist-based Pulse Ox sensor monitors blood oxygen saturation levels to support advanced sleep monitoring and altitude acclimation.
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.
SAFETY AND TRACKING FEATURES
If you feel unsafe or if your watch senses that an incident occurred, the Assistance and incident detection features send your location to emergency contacts. Incident detection is enabled by default for select activity profiles only.
