Updates for February 12, 2026

  • Fixed Garmin/Wahoo workout sync showing intervals without power targets — cycling workouts are now converted to structured Intervals.icu format before upload, ensuring head units display correct power targets for each interval
  • Fixed regenerating weekly plan resetting periodization cycle position — if you were 2 weeks into a 3:1 Build/Recovery cycle and regenerated, the plan would schedule 3 more build weeks before recovery instead of 1; the plan now respects your current position in the periodization cycle
  • Added recommended RPE and feel indicators to post-workout feedback form — after completing a workout, the feedback form now shows the expected RPE range (based on workout stimulus type) and recommended feel (based on your recovery score), helping you calibrate your perceived effort
  • Fixed weekly plan workout durations deviating significantly from configured availability — workouts that are too long or too short (beyond ±10%) are now caught and replaced with correctly-timed templates, so a 2h target won't produce a 2h58m or 1h30m workout
  • Fixed weekly plan assigning unrealistic pure Tempo workouts for long rides — rides over 2.5 hours are now automatically set to Endurance intensity, preventing physiologically impossible sessions like 4 hours of continuous tempo
  • Fixed weekly overview in daily email showing "Rest" for days that have scheduled workouts — today's planned workout now correctly appears in the week overview
  • Fixed post-workout analysis flagging normal heart rates as "quite high" — the AI now knows your LTHR and Max HR from Intervals.icu settings and interprets heart rate relative to your personal thresholds, not absolute values
  • Fixed race day email showing literal backslash-dash characters instead of line breaks in pacing and warmup sections
  • Fixed "Reset Calendar" not clearing existing workouts before regenerating — previously, resetting your plan would create duplicate workouts alongside the old ones instead of replacing them
  • Fixed weekly plan showing "Peak" phase while the dashboard shows "Taper" — near phase boundaries, the weekly plan and training plan timeline were calculating the phase independently from the dashboard, ignoring hysteresis. All surfaces now use the same central phase calculation
  • Fixed dashboard readiness status badge flickering between different labels during page load — the label now shows a loading state until the AI assessment is ready, then displays once with the final result
  • Fixed intermittent crash on Settings page on Mobile Safari caused by a hydration mismatch when swapping the theme picker skeleton for the actual dropdown — the page now waits for full hydration before rendering settings content
  • Fixed intermittent crash on TrainNow page on mobile browsers — simplified tooltip rendering to eliminate cascading state updates during page load that could overflow the call stack on devices with limited memory
  • Fixed stale eFTP used for athletes who train both indoors and outdoors — Intervals.icu maintains separate eFTP models per sport type, so the app now uses whichever was updated most recently instead of always defaulting to outdoor
  • Fixed AI thinking/reasoning text leaking into workout descriptions — internal chain-of-thought like calculation notes and self-corrections are now filtered out before displaying workouts
  • Fixed fitness trend chart showing tomorrow's date for athletes in western timezones — the dashboard now uses your local timezone instead of server UTC time to determine today's date
  • Fixed workout profile chart sometimes showing phantom intervals (e.g., Sweet Spot blocks) that don't exist in the actual workout text — when the AI generates a workout in a format the chart parser can't recognize, the chart is now hidden rather than showing misleading template-based intervals
  • Fixed Sweet Spot and Tempo power targets being 3-5% lower than expected — the wellness-based intensity reduction was incorrectly applied to all zones; it now only reduces threshold (Z4) and above, keeping moderate-intensity targets at their correct values
  • Fixed post-workout analysis overwriting your activity description in Intervals.icu — the IntervalCoach analysis is now appended below your existing notes instead of replacing them, and re-analyses update only the IntervalCoach section
