After the test, the training
Aevox interprets your CPET, then carries the same physiology forward into your training. Three pillars — metabolic efficiency, economy, fatigue resistance — anchored to your test and tracked across every run.
Most athletes get a PDF, learn their VO₂max, and never see those numbers again. Aevox keeps the test alive — anchoring three measurable pillars to your physiology and watching them move as you train. Every number traces to your data, your assumptions, your test.
Your trajectory matters more than any single snapshot. We track changes over months and years.
Every number traces to an assumption, a citation, and your data. Nothing is made up.
When confidence is low, we say so. When data is missing, we tell you what we need.
The three pillars
MEI — full-spectrum substrate efficiency
Not just your VO₂max — your metabolic efficiency across every intensity. We integrate fat and carbohydrate utilization from rest to max effort into a single score that tracks metabolic health and flexibility over time.
Cost of movement at goal pace
How efficiently you convert oxygen into speed. We measure the cost of holding your goal pace over time — corrected for environmental factors so the trend is real.
How you hold up when it matters
Can you hold it together late in a race? We measure how your body responds under sustained effort — your durability signature, tracked over time.
How it works
Upload your Garmin export, Strava activities, Whoop data, or a CPET lab report. We ingest FIT files, wellness data, and structured PDFs.
Three pillar scores computed from your actual physiology — with confidence levels, trend lines, and every assumption documented.
Your scorecard shows what's improving, what's stalled, and what to focus on next. Your coach sees it too — flagged metrics route for human review before you act.
Not just a dashboard
Ask anything about your physiology in plain language. Aevox doesn't just show you numbers — it explains what they mean, why they changed, and what to do about it.
Every answer is grounded in your actual data. When confidence is low, it tells you. When a question needs human expertise, it routes to your coach automatically.
“Why did my economy get worse this month?”
Your cost at goal pace rose 3.1% over the last 4 weeks. Two factors: a heat wave in weeks 2–3 added ~2.8% after environmental correction, and your long run volume dropped 18%. The heat effect will wash out — the volume drop is worth addressing.
“Am I ready for a 3:15 marathon?”
Based on your current profile: your metabolic efficiency supports it (MEI 72, crossover at 74% VO₂max), but your durability score suggests a 4–6% fade after 90 minutes at goal pace. I'd recommend 2–3 more back-to-back long runs before taper. Want me to flag this for your coach?
“What should I focus on this training block?”
Your economy is your strongest pillar — it's been stable for 12 weeks. Durability is your limiter. Specifically: your cardiac drift accelerates after 75 minutes. Priority this block: one weekly long Z2 run extending past 90 min, and consider adding eccentric downhill work.
Real questions. Answers grounded in your three-pillar profile.
Under the hood
Most platforms hide their methodology. We version ours. Every modeling choice is an explicit assumption — with citations, review dates, and validation criteria. Here's what one looks like:

Every modeling choice in our system is structured like this — cited, versioned, and validated against real athlete data before it touches your scorecard.
