Understanding the Garmin Forerunner Lineup

The Forerunner Philosophy

Garmin positions Forerunner watches across three distinct categories:

• Best for: Elite athletes, data enthusiasts

Model Numbering System Explained

Garmin's numbering system follows a pattern:

• Lower numbers (55, 165, 255) = Smaller case size, lighter weight
• Higher numbers (65, 265, 965) = Larger display, longer battery
• "Music" suffix = Onboard music storage (300+ songs)
• "S" suffix (older models) = Smaller variant

Current Active Models (2025):

• Forerunner 55
• Forerunner 165 / 165 Music
• Forerunner 265 / 265S

Future Forerunner Releases: Predictions for 2025-2026

Expected: Forerunner 165S

Predicted: Q3 2025 Predicted Price: $249-299 USD / £220-270 GBP / €270-330 EUR / $429-499 AUD

The FR 165 has been wildly successful, but there's an obvious gap: no small version.

Expected features:

• 39mm case (vs 43mm)
• Lighter weight (36-37g)
• Slightly smaller AMOLED (1.0-1.1")
• Same features as FR 165
• 17-18 hour GPS battery

Why it makes sense:

• FR 255S and 265S exist for small wrists
• FR 165 is "medium" sized at 43mm
• Huge market for compact AMOLED watches

Likely: Forerunner 955 Successor

Predicted: Q2-Q3 2025 Predicted name: Forerunner 975 or 1075 Predicted Price: $549-649 USD / £479-569 GBP / €599-699 EUR / $899-1,049 AUD

The FR 955 launched in 2022, making it due for an update.

Expected features:

• Updated heart rate sensor (Elevate v5?)
• Improved battery efficiency
• ECG functionality (rolled out globally)
• Better solar charging efficiency
• Same MIP screen (not AMOLED)
• Training Readiness added

Why MIP will stay:

• Battery life is the selling point
• AMOLED exists in FR 965
• Market differentiation
• Ultrarunners prefer MIP readability

Possible: Forerunner 365

Predicted: Q4 2025 or 2026 Predicted Price: $599-649 USD / £520-570 GBP / €650-700 EUR / $999-1,049 AUD

A potential new model slotting between FR 265 and FR 965.

Hypothetical features:

• 1.3" AMOLED display
• Full mapping (like 965)
• 28-30 hour GPS battery
• 16GB storage
• Premium materials
• Fills the "AMOLED + maps but not $700" gap

Why it might happen:

• $200 gap between 265 ($500) and 965 ($700)
• Many want maps but not $700 price tag
• Would complete the AMOLED lineup

Wild Card: Forerunner 1065

Predicted: 2026+ Predicted Price: $799-999 USD / £699-869 GBP / €849-1,099 EUR / $1,299-1,599 AUD

A halo product pushing boundaries.

Speculative features:

• Massive 1.5"+ AMOLED display
• 40+ hour GPS battery (on AMOLED!)
• Advanced blood oxygen monitoring
• Skin temperature sensor
• Premium titanium construction
• Advanced coaching AI
• Satellite communication (like inReach)

Why it could happen:

• Garmin Epix 2 Pro exists at $1100

• Competition from Apple Watch Ultra
• Technology is advancing rapidly
