Every month,
a stronger stride.

Drop your Garmin data export ZIP as is, or its folder: every run plus years of sleep, nightly HRV, stress, Body Battery, SpO₂, steps, weight and VO₂max in one upload. Other sports and device files are skipped before upload. Runs edited in Garmin Connect no longer import twice.

Drop the Zepp export ZIP, password-protected too, or its folder: runs, sleep stages, steps, weight and minute heart rate in one upload. HR is matched to each workout and night, checked against the hour before, and DST-safe. Re-imports enrich, never duplicate; Garmin data keeps priority.

Amazfit resting HR uses Garmin's definition: the lowest 30-minute average of each day's minute HR. Overnight HR uses only staged sleep. Sparse or workout-skewed days are skipped, not guessed. Both feed recovery, readiness and AI insights.

New Health charts: overnight HR, time awake during sleep, steps, movement distance and body weight. Plus deep/light/REM split, awakenings and bedtime/wake-time consistency.

New Health cards for all-day and sleep stress, Body Battery peak and low, lowest overnight SpO₂ and intensity minutes. The HRV chart shades your personal baseline range, and nightly HRV from the export takes priority over Sleep.csv's 7-day average.

Runs from the Garmin export show your RPE and how you felt, plus session load (RPE × minutes).

AI summaries can run on Claude (Anthropic), OpenAI or NVIDIA Nemotron. Opt-in; providers receive only calculated training facts, never your name, email or password.

Stored per-run stream summaries and incremental running load make Overview, records and intensity load faster on years of history. Large imports use less memory and keep the app responsive.

Evidence-based 5K and 10K guides plus one-page cheatsheets: routes by current race time, weekly structure, key workouts, block progression and race week.

Experimental FIT import for COROS, Suunto, Polar and Apple Watch via HealthFit. Clearer error hints. Sleep and recovery data still need a Garmin or Amazfit import.

Import recorded runs as TCX, including summary-only indoor activities. Trackpoints unlock pace/HR charts, lap splits and detailed analysis using available sensor data. FIT, TCX and CSV duplicates merge, with FIT data preferred.

Yearly activity heatmaps on Overview with daily details. Color by distance, duration, running load, run count, elevation gain, average HR, pace or calories. Includes median runs/week across each year’s active period.

Critical-speed duration and best-effort distance views: 400/800 m, mile, 3/5/10K, HM/M. Select Daniels equivalents from a mile; tooltips show time, pace and gaps. View/reference persist while navigating.

Target mileage/520 weeks; build/steady/recovery; editable starting runs; km/miles; 30-day distances. Optional short days above preferred lengths; frequency redistributes volume with two-week holds. Linked evidence vs. planning assumptions. No account.

Upcoming runs: 30-day history. Optional ceilings update generated weekly running-load/fitness projections; coach workouts get warnings only.

No ACWR-only cutbacks/35% long-run cap. Dashboards/AI/docs clarify coaching assumptions vs. session-distance observations.

Daniels-based paces replace averages; recent race-like efforts can refine Threshold via CS, Tanda only Marathon. Compare log-endurance/MAS race-proxy/Morton with suitable data. Popovers: sources, dates, limits.

Pace-based running load shares dashboard race windows/CS. Fits exclude recovery/preparation titles and unstable Morton fits. Historical dates respected; unavailable models reset selection.

A new Compare page lets you pick any metric, choose 2–4 date ranges, and see box plots with mean difference, confidence interval, and effect size for every pair. Includes cardiac efficiency, aerobic cost, decoupling and pace fade.

Create a read-only link in Settings — no account needed on their side. It shows load, intensity, training paces, heart-rate zones, and a 90-day activity log. Rotate or revoke anytime.

Pick km or miles in Settings. Distance, pace, elevation, splits, insights, AI summaries and free tools all follow your choice.

Each activity now shows its running load and which method calculated it — pace stream, average pace, or heart rate.

Phase paces now start from your predicted race pace, with conservative-to-aggressive regimes and custom phase splits — works without an account.

Your active plan is no longer hidden, settings changes recalculate in place, and pace formatting is fixed. Failed loads and AI summaries now explain what went wrong, and the fitness/fatigue/form chart is back on the overview.

Personal records through the marathon, critical speed, long-run durability, FIT splits and goal-race comparisons. Heart rate at a fixed pace now tracks comparable steady runs, adjusting for hills when possible; raw cardiac efficiency remains available.

Weekly time in easy, grey and hard heart rate zones with a polarization index, plus training monotony and strain to flag weeks that were too uniform.

Plans are now built from structured weekly templates with clearer progress tracking. Skipped weeks and injury adjustments shift the rest of the plan automatically.

Dashboard, plan and content pages were rebuilt with better contrast and consistency. New accounts get a getting-started checklist, you can import up to 1,000 FIT/CSV files at once, and pages load faster and more reliably.

A new chart reveals how pace changes with heart rate, using monotonic slices to make the trend easier to trust. The zone calculator also received clearer inputs and more accurate guidance for setting training intensities.

Training data now comes with concise narrative summaries, configurable controls, and a more efficient generation flow.

The planning experience was redesigned with stronger calculations, clearer week structure, and more dependable plan states.

Client-side caching, smarter route warmup, and refined loading feedback make moving between insights feel immediate.

A complete training-plan experience arrived, connecting current fitness, weekly sessions, and race goals.

Activity pages gained richer statistics and new charts for cadence, stride, efficiency, and pace progression. Garmin FIT files can now be imported directly, with improved duplicate detection and clearer import results.

Race and training pace calculations were upgraded with improved equations and corrected Daniels formula behavior.

Google authentication and profile avatars made account setup quicker and more personal.

The blog and cheatsheet library launched with evidence-based guides across training, recovery, heart rate, and racing.

Pace, race prediction, strategy, heart-rate zones, training paces, and calorie tools became available to every runner.

New documentation, feedback channels, and support workflows made it easier to get started and get help.

Prerendering, image optimization, and careful loading improvements significantly reduced time to first view.

Dashboard, account, and public pages were rebuilt into a clearer and more consistent interface.

Practical pace and race tools joined the analytics platform as freely available resources.

Every dashboard section gained contextual insights that turn calculated metrics into useful training direction.

The race predictor was rebuilt around the Jack Daniels formula for more credible equivalent performances.

Key readiness, load, recovery, and trend signals were reorganized to make daily decisions faster.

The project became Runima, with a new identity focused on serious, data-oriented runners and coaches.

CTL, ATL, and TSB came together in one chart to show fitness, fatigue, and form over time.

Readiness labels, recent activities, and month-over-month summaries created a useful daily overview.

Activities gained running-load calculations to quantify training demands consistently across sessions.
