Garmin Edge 850 GPS Cycling Computer with Advanced Training Metrics & Navigation

The Garmin Edge 850 sits above the Edge 840 in Garmin's cycling computer lineup, bringing a colour touchscreen with tactile button controls, up to 24 hours of GPS battery life, and an expanded suite of performance analytics designed for cyclists who want the deepest possible insight into their training and racing.

Navigation is powered by multi-GNSS technology (GPS, GLONASS, and Galileo) for reliable, accurate positioning across all terrain types and environments. The ClimbPro feature previews upcoming climbs with full gradient profiles, remaining ascent, and real-time effort data — essential for pacing yourself intelligently on hilly routes or sportives. Beyond navigation, the Edge 850 tracks VO2 max, lactate threshold, recovery time, and power zones when paired with compatible sensors, giving you a genuinely comprehensive picture of your fitness and fatigue over time.

A standout addition on the Edge 850 is fuelling guidance and calorie tracking, which monitors your energy expenditure and prompts you to eat and drink at the right intervals — a feature that makes a real difference on rides of three hours or more. Post-ride, everything syncs seamlessly to Garmin Connect™ for analysis, social sharing, and structured training plan management. Compatible with Strava, Komoot, and TrainingPeaks®. Browse the full Garmin range, our computers and GPS collection, or explore compatible power meters and heart rate monitors to unlock the full analytics suite.

With 24 hours of GPS battery life, the Edge 850 is equally at home on a two-hour training ride and a full-day sportive or ultra-endurance event. Select your preferred option above and add to basket.

What It's Good For

• Cyclists wanting a step up from the Edge 840 with expanded analytics and longer battery life
• Advanced training metrics including VO2 max, lactate threshold, recovery advice, and power zone tracking
• ClimbPro ascent planning with gradient profiles and real-time pacing data on every climb
• Fuelling guidance and calorie tracking for optimal nutrition management on long rides
• Reliable multi-GNSS positioning (GPS, GLONASS, Galileo) across all terrain types
• Up to 24 hours of GPS battery life for extended rides and multi-stage events
• Seamless sync with Garmin Connect™, Strava, Komoot, and TrainingPeaks®

What It's NOT Good For

• Casual riders who don't need advanced training analytics — the Edge 540 or Edge 840 may be more appropriate
• Riders without a power meter or heart rate monitor who want the full analytics suite — compatible sensors are required for metrics like VO2 max and lactate threshold
• Those specifically wanting a larger display — the Edge 1040 offers a larger screen
• Non-cycling activities — the Edge 850 is optimised specifically for cycling performance and navigation

Frequently Asked Questions

How does the Edge 850 compare to the Edge 840?
The Edge 850 builds on the Edge 840 with a longer battery life (up to 24 hours vs the 840's standard GPS mode), expanded analytics including fuelling guidance, and additional performance metrics. If you ride long or want the most comprehensive data set, the 850 is the stronger choice.

What sensors do I need to unlock the advanced metrics?
For VO2 max, lactate threshold, power zones, and cadence analysis, you'll need a compatible power meter and heart rate monitor. The Edge 850 supports ANT+ and Bluetooth sensors from a wide range of manufacturers. Browse our power meters and heart rate monitors for compatible options.

How does fuelling guidance work?
The Edge 850 monitors your calorie expenditure in real time and provides on-screen prompts to eat and drink at appropriate intervals based on your effort level and ride duration. It's particularly useful on rides of three hours or more where nutrition timing has a significant impact on performance and recovery.

Can I use the Edge 850 without pairing any sensors?
Yes — the Edge 850 works fully as a standalone GPS cycling computer, providing speed, distance, elevation, navigation, and ClimbPro data without any additional sensors. Pairing a power meter and heart rate monitor unlocks the deeper analytics and coaching features.
