Introducing Runima: Coach-Grade Running Analytics, Free
Runima turns your smartwatch activity history into the training-load, readiness, and performance analysis serious runners act on — and it's free.
Your smartwatch already records everything — every kilometre, every heartbeat, every recovery day. The problem has never been data. It's that the data sits in a feed, scrolling by one workout at a time, with no way to see the trend underneath it.
Runima is built to fix exactly that. Import your activity history and Runima runs the same training-load and performance analysis a good coach would do by hand, then charts it so you can see where you actually stand. Today we're launching the first public release, and the core analysis is free.
Bring your own data
Right now Runima imports your activity history straight from a Garmin Connect export — your runs, heart-rate streams and daily health metrics. You don't enter anything by hand; the analysis is built entirely from what your watch already measured.
What you get in this release
Training load, the way coaches model it
Runima builds the full Performance Management picture from your history:
- CTL, ATL and TSB — fitness, fatigue and form on one timeline, so you can see whether a hard block left you sharp or buried.
- Acute:Chronic Workload Ratio — the progression guard-rail that flags when you're ramping faster than your body has adapted to.
- Weekly distance and load summaries — the consistency view that the single-workout feed never gives you.
Readiness and recovery at a glance
The overview surfaces readiness, recovery and fatigue cards so you can answer the only question that matters before a quality session: is today the day to push, or the day to back off?
Performance trends
- Pace progression over time, so improvement shows up as a line, not a feeling.
- Cardiac efficiency — pace relative to heart rate — to see fitness gains that raw pace alone hides.
- Stride and form metrics from your runs.
- Race predictions and training zones derived from your own history, not a generic table.
Plain-language insights
Numbers are only useful if you know what to do with them. Alongside the charts, Runima writes short, plain-language insights that point out what changed and why it matters — built from your trends, not generic advice.
Why we built it this way
Runima is for runners who take a scientific approach — people who'd rather see the methodology than be told to trust a black-box score. Every metric here is a recognised endurance-training model, computed transparently from your own activities. No invented numbers, no vanity scores.
What's next
This first release is focused and honest about its scope. On the roadmap: broader analysis, more health signals, and tooling for coaches who want to work with their athletes' data. We'll share those as they ship — and we'll keep writing up the science behind each metric here on the blog.
Import your history, look at your trends, and stop guessing.
