Know when to push. Know when to rest.
Runima turns your smartwatch data into clear answers: Am I improving or overtraining? Am I ready to race? Real sports-science metrics — no black boxes.
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.
- Fitness (CTL) vs. fatigue (ATL)
- Form (TSB) for race timing
- ACWR injury-risk guard-rail
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 numbers your coach would run, on tap
Personalised heart-rate zones from the method you trust — Karvonen, lactate threshold, MAF and more — alongside training-pace, race-time and strategy calculators built from established formulas.
- Five heart-rate zone methods
- Training paces from a recent race
- Race-time and strategy planners
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. 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.
