Intelligent Endurance

Ryun is a device-agnostic AI platform that fuses performance data with validated sports science

Turning fragmented signals into actionable intelligence.

/ Platform

The Intelligence Chain

From raw performance signals to actionable training intelligence. Five steps. One unified system.

01

INGEST

Device Agnostic Data Collection

Connect your wearable. Real-time sync via webhooks. One unified data layer. Compatible with Suunto, Polar, Apple Health, and more coming soon.

02

PROCESS

Validated Sports Science

VDOT calculations. TSS normalization. CTL/ATL modeling. Recovery scoring. Every algorithm traceable to peer-reviewed research.

03

ANALYZE

Pattern Recognition

HRV trends. Sleep quality correlation. Training load periodization. Identify what works. Eliminate what doesn't.

04

PLAN

Adaptive Training Plans

AI-generated periodization. Every workout calibrated to current fitness. Plans that evolve with you.

05

EXECUTE

Actionable Intelligence

Daily recommendations. Race predictions. Recovery windows. The right workout at the right time.

/ Science

Grounded in Research.
Not Marketing.

Every algorithm is traceable to peer-reviewed literature. Daniels, Coggan, Banister, Seiler. The LLM is a interface—not the intelligence. The science is the intelligence.

Daniels' Running Formula

VDOT equivalence tables calibrate your training paces to your current fitness level. Every interval, every threshold run, precisely tuned.

Banister Impulse-Response

The mathematical model behind CTL, ATL, and TSB. Fitness and fatigue as exponentially weighted moving averages.

Coggan Power Metrics

TSS quantifies training load across modalities. Heart rate, pace, power—normalized to a common language.
