Running Analytics That Help You Train Smarter
Your smartwatch data, decoded. Know if you're improving, overtraining, or race-ready — backed by real sports-science metrics.
Import your data in 2 minutes. Free. No credit card.
Your whole season, finally making sense.
Import once and it's all on one screen — fitness, fatigue, readiness and form, filled in automatically.
Catch overtraining before it catches you
Fitness, fatigue and form on one timeline — plus the acute:chronic workload ratio, the relationship sports-science links to injury risk. Runima flags a load spike before you feel the damage, and tells you exactly how far is safe to go next week.
- Fitness (CTL) vs. fatigue (ATL)
- Form (TSB) for race timing
- A weekly volume ceiling that adjusts to your training
Watch your engine get stronger
A single performance score backed by the metrics underneath it: VO₂max, cardiac efficiency and stride length, each trended over time so real improvement shows up as a line — not a feeling.
- Estimated VO₂max from your runs
- Pace-per-heartbeat efficiency
- Stride and economy trends
Recovery you can actually see
Sleep quality, sleep debt, heart-rate variability and resting heart rate, tracked as trends instead of single nights — so you know whether you're truly recovering or quietly digging a hole.
- Sleep score, duration & consistency
- HRV and resting-HR trends
- A recovery score you can act on
The calculations a coach would run — done automatically
Get personalized heart-rate zones using the method that fits you — Karvonen, lactate threshold, MAF and more. Then calculate your training pace, predict your race time, and plan your race strategy, all built on established sports-science formulas.
- Six heart-rate zone methods
- Training paces from a recent race
- Race-time and strategy planners
A training plan that adapts to your week, not just your calendar
Runima projects your fitness, fatigue and form forward from your current training, week by week — then keeps adjusting as you actually train. Miss a session, log an injury, or have a rough week, and the plan reduces load and reshapes itself instead of pretending nothing happened.
- Projected CTL/ATL/TSB for every week ahead
- Auto-adjusts after missed sessions or injuries
- Pause, cancel, or take manual control anytime
Your numbers, explained in plain English
Every dashboard page comes with a short AI-written summary that reads your actual metrics back to you in plain language — and, if you opt in, adds its own brief take on patterns or risks worth watching. It never invents a number: every claim is checked against your real data before it's shown.
- Plain-language summary on every page
- Optional AI interpretation you can turn off anytime
- Every output verified against your real numbers
Want more than the CSV gives you? Drop in the raw FIT file
CSV exports get you fast, aggregate stats. For per-second detail — lap splits, pace and heart-rate charts, automatic interval detection — import the raw .FIT file straight from an activity's export menu instead. Runima reads both, so you choose the level of detail per activity.
- Per-second pace and heart-rate charts
- Automatic lap and interval detection
- Mix CSV and FIT files freely
You have the data. You just can't use it.
Your smartwatch collects thousands of data points. Turning them into training decisions is the hard part.
Your watch shows numbers
Heart rate, pace, sleep, recovery — hundreds of numbers every run. But what do they actually tell you about tomorrow's workout?
Spreadsheets don't scale
Exporting to spreadsheets and tracking your training load by hand — it works until it doesn't. And it never catches the trend you miss.
Pro tools cost pro prices
TrainingPeaks charges $20/month, and most of it goes unused. You just want to know your fitness, your fatigue, and your injury risk.
From data to insights in minutes
No manual setup, no spreadsheets. Just your training data and the metrics that actually tell you something.
Export from Garmin Connect
Log in to Garmin Connect, export your activities as CSV — or grab the raw .FIT file for per-second detail. Takes 30 seconds.
Upload to Runima
Drag and drop your files. The importer auto-detects activities, sleep, and HRV data. No manual mapping.
See Your Dashboard
Readiness score, training load, injury risk, race predictions — computed and ready. Update anytime with new exports.
Open methodology. Every formula documented.
The same models published in peer-reviewed sports science journals. You can verify every calculation.
Computational Models
We apply established sports-science models to your own training history — the fitness-fatigue model behind your form, proven formulas for race prediction, and VO₂max estimation from your aerobic activity data.
Physiological Metrics
We track your heart-rate variability (HRV), training load, and acute:chronic workload ratio against your personal baseline to surface how your body is recovering and adapting.
Statistical Rigor
Every prediction comes with a confidence range, not a false promise. We don't guess—we calculate from your real data, publish how accurate our models are, and keep checking them against your results.
Stop guessing.
Start knowing.
Import your training data and see your fitness, fatigue, injury risk, and race predictions in one dashboard. It's free while we're in early access — and your feedback shapes what we build next.
