COROS Spring 2026 Update: PacePro, ClimbPro and Hyrox Mode Explained
COROS has released its biggest firmware update of the year, bringing three headline features to its existing watch lineup. The Spring 2026 update adds PacePro-style race pacing, Garmin ClimbPro-rivalling hill alerts, and a new Hybrid Fitness mode — all via a free over-the-air update for current and previous generation watches.
Pace Strategy: Smart Race Pacing
The new Pace Strategy feature lets you load a specific course or target distance, then provides real-time pacing guidance both in the COROS app and on your watch. It accounts for terrain elevation, and you can configure positive or negative split strategies. For ultra-distance events, it automatically adjusts for pace decay over time — a thoughtful touch for IRONMAN athletes who know that holding the same pace across 180km on the bike is rarely realistic.
Hill Alerts: Real-Time Climb Guidance
Hill Alerts is COROS’s answer to Garmin’s popular ClimbPro feature. When approaching a significant ascent or descent, your watch displays the remaining distance, elevation gain, and average gradient. This is particularly valuable for hilly bike courses and undulating run legs where managing effort on climbs is the difference between a strong finish and blowing up.
Hybrid Fitness Mode
The new Hybrid Fitness mode targets multi-discipline workouts with automatic activity detection when switching between stations. While designed primarily for Hyrox-style events, triathletes doing gym-based cross-training sessions will find it useful for tracking transitions between strength work, rowing, and running without manually switching modes.
Which Watches Get the Update?
The Spring 2026 update rolls out to the COROS Pace 4, Pace Pro, APEX 2, APEX 2 Pro, Vertix 2S, and Vertix 2. Previous-generation models receive the update alongside current hardware, which is a strong commitment from COROS to supporting older devices. Update via the COROS app on iOS or Android — the firmware should appear automatically when you sync your watch.
Should Garmin Users Be Worried?
This update narrows the gap between COROS and Garmin significantly. Pace Strategy and Hill Alerts were two of Garmin’s strongest differentiating features, and COROS now offers comparable functionality at a lower price point. For triathletes weighing up a COROS Pace 4 (around £230) versus a Garmin Forerunner 265 (around £380), the value proposition just got even more compelling.
