Explainable engine
Every session has a written rationale in plain language: why it's scheduled today, what it does for you and how it fits into the week. You don't have to trust the plan blindly — you can read it.
AI training coach for endurance sports
AI training plans for marathon, triathlon & gran fondo — explainable, not a black box.
Peakora is an AI coach for marathon, triathlon, duathlon and gran fondo. Every session comes with a rationale — from a deterministic training engine, not a black box. Built and hosted in the EU.

Differences
Why Peakora is different
Privacy by design
Your training data lives locally on your device. AI requests run through an EU proxy that removes personal data before anything reaches a language model. No trackers, no ad networks.
Honest pricing
€149 per year for everything — no tiered pricing, no hidden limits, well below the price of established training platforms. The pricing logic is laid out openly on this page.
Features
Four building blocks, one system
This is what a rationale in the plan reads like: "Tuesday, 60 min bike in zone 3 — after your easy 3-hour ride at the weekend, today is the intense session of the week. It keeps your threshold stable without raising the weekly load by more than 10 %." Numbers from your training, not from a textbook.
A plan that thinks ahead
Your training plan follows a clear periodization — base, build, peak, taper — and manages load via the Training Stress Score (TSS). The intensity distribution follows the 80/20 principle: 80 % easy, 20 % intense.
- Periodization: base, build, peak, taper
- 80/20 intensity distribution and TSS load management
- Multiple goals in parallel — with A/B/C priority
- Base-building mode with no race pressure at all
24-hour recovery monitor
A battery indicator instead of a bare number: Peakora combines your form (TSB), your sleep and the time since your last session — and tells you concretely what makes sense today.
The score is made up of three components: 65 % form from the TSB model, 35 % sleep factor from last night — plus a recovery bonus when enough time has passed since your last hard session. Less than six hours of sleep pushes the score down noticeably, and the daily recommendation comes out correspondingly more cautious.
- Recovery score from form (TSB), sleep and time since last session
- A concrete daily recommendation instead of an abstract metric
- Transparency: every component of the score can be inspected
Fueling with a plan
The fueling calculator works out carbohydrates, sodium and fluids per hour — matched to the estimated race time of your target event. Plus recipe ideas that fit your eating preferences.
- Carbohydrates, sodium and fluids per hour
- Estimated race time from your target event
- Recipe ideas matched to your eating preferences
- Everything as a PDF for your race bag
More than running
Endurance isn't built on the road alone. Peakora ships with an exercise library with video demos — either for home (bodyweight & band) or for the gym (machines & free weights). The AI coach answers training questions and adjusts your plan directly in the chat — always with your confirmation.
- 46 video exercises: stretching, strength & core — at home or in the gym
- Guided workout mode with set and rest timers
- AI coach adjusts the plan via chat: move, drop, make easier
- Route suggestions as loops from your location — road or gravel
- GPX export: direct "Open in app" for Garmin Connect, Komoot & co.
A coach that course-corrects
Peakora notices when the week didn't go as planned. The weekly check analyses adherence, load and sleep and suggests exactly one small adjustment — at most ±15 %, only with your confirmation, never silently.
- Weekly check: adherence, TSS completion and sleep in review
- Missed a quality session? A make-up suggestion with a 48-hour rule instead of skipping at all costs
- Plan changes only after confirmation — the plan stays stable
- Automatic sync with Strava, Polar and Suunto

Which zones do you train in?
The zone distribution shows whether the 80/20 rule is being kept — 80 % easy, 20 % intense.
80 % easy (Z1–Z2) · 20 % intense (Z3–Z5) — heart-rate and power zones included.
Your form curve
Fitness, fatigue and form over twelve weeks — the Banister model, made visible.
Fitness (CTL)
Fatigue (ATL)
Form (TSB)
Filled in automatically: Syncing with Strava, Polar and Suunto works directly — completed sessions land in the calendar on their own. Garmin users import their sessions via FIT/GPX file or connect Garmin through the Strava bridge; native Garmin integration will follow as soon as Garmin issues new API access again.
Reports
Your plan as a PDF — for the race bag
Export your training plan and fueling plan with one tap as coloured landscape PDFs: weekly load as a bar chart, phases colour-coded, fueling with an hourly schedule. Here are two real examples from the app:
Training plan (example, 7 pages)
Open example PDF → Weekly load bars by phase, sport chips in colour, every session with zone, duration and TSS.
Fueling plan (example, 2 pages)
Open example PDF → Gauge cards with recommended range, race-day hourly schedule, gut-training protocol.
PDF export from the Athlet plan upwards. On Android the share menu opens — save, print or pass it on directly.
Technology
The engine in detail
- Banister load model. ATL, CTL and TSB are calculated as exponentially weighted averages — an established model in sports science.
- Periodization with 3:1 deload. Three loading weeks, one deload week. The deload is part of the plan, not an accident.
- Capped progression. Load increases are capped at 8–10 % per week — as protection against overload.
- Deterministic, not a black box. The same inputs produce the same plans: reproducible, verifiable, traceable.
- AI only as the explanation and chat layer. Mistral Small, hosted in the EU, writes the rationales and answers questions — but never generates the plan.
The difference from a human coach: a flesh-and-blood coach knows your daily life, but cannot recalculate every night — and costs several times more. Peakora does not replace technique coaching, but takes over the number work: the deterministic engine recomputes your load every day and backs every session with a written rationale — no black-box LLM improvising a plan. Developed in Austria, GDPR-compliant, servers in the EU.
Open-source engine principles: Training Stress Score, 80/20, supercompensation.
Concrete
What your training week looks like
An example from a build week of marathon training (goal time 3:45 h, week 8 of 16):
| Day | Session | Duration | Intensity |
|---|---|---|---|
| Monday | Rest day — recovery is training | — | — |
| Tuesday | Tempo run with threshold blocks | 60 min | Z3 |
| Wednesday | Strength training (legs + core) | 35 min | — |
| Thursday | Easy endurance run | 50 min | Z1–Z2 |
| Friday | Stretching & mobility | 15 min | — |
| Saturday | Intervals 6 × 1000 m | 55 min | Z4 |
| Sunday | Long run | 120 min | Z2 |
Every session comes with a written explanation — why it sits on that day, what it does and how it fits into the weekly load (TSS). If a day doesn't work, you move the session via chat with the AI coach — the plan recalculates the week.
Evidence
Scientific foundations
Peakora doesn't reinvent exercise science — the engine implements established, peer-reviewed concepts:
- 80/20 (polarised) training. The intensity distribution of successful endurance athletes: ~80% easy, ~20% hard. Review: Seiler & Tønnessen, “Intervals, Thresholds, and Long Slow Distance” (sportsci.org). Deep dive on the blog: 80/20 training.
- Banister fitness-fatigue model (TSS, CTL, ATL, TSB). The classic training-load model — literature via PubMed. Explained on the blog: Training Stress Score.
- Tapering. Reduce volume, keep intensity: the evidence-based method for race-day form. On the blog: Tapering — the final 14 days.
- GDPR-compliant data protection. Personal data is processed under European law — background: gdpr.eu (official EU GDPR resources).

Recipes, route suggestions and PDF export are included in the Athlet or Elite plan.
How does Peakora create the training plan?
Peakora uses a deterministic training engine — no language model builds your plan. The engine calculates your load with the Banister model (TSS), distributes intensity using the 80/20 principle and periodises into base, build, peak and taper. The AI (Mistral, EU) explains every session and answers questions — the plan logic stays transparent and reproducible.
How much does an AI training plan cost?
Start is free forever. Athlet costs €59 per year (or €6.99 monthly), Elite €149 per year (or €14.99 monthly) — all prices incl. 20% VAT, cancel anytime, no hidden extras.
Is my training data safe with Peakora?
Yes. Peakora is GDPR-compliant: your data stays on your device and encrypted on EU servers. There are no trackers, no ad networks and no data selling. AI requests pass through an EU proxy that removes personal information before anything reaches the language model.
Which sports have AI training plans?
Running (5K to marathon), triathlon (sprint to Ironman), gran fondo and road cycling, duathlon and swimming. Every plan also includes strength, core and mobility sessions — endurance doesn't work without stability.
What is the difference between Peakora and TrainingPeaks?
