Train Smarter. Track Every Station.

HYROX Coach is the first AI-powered training platform that connects with Apple Watch & Garmin to record every station split, pace, and heart rate — then builds personalized, data-driven plans that evolve as you train.

I built this out of frustration. Existing fitness apps treat HYROX like a long run. There was no way to track stations, analyze pacing, or see where I broke down in a simulation. So I built the tool I needed to train smarter.

From 103→77 kg to first HYROX finish — I'm turning hard-won lessons into an AI coach that understands your stations, not just your splits.

Core Features

🏃‍♂️ Station-by-Station Tracking

Log sleds, runs, lunges & wall balls directly on your watch — with real-time splits, HR, and pacing. No more guessing where you broke down.

📈 Adaptive AI Plans

Training evolves weekly based on watch data, compliance, and station performance. The AI learns your patterns and adjusts accordingly.

🧠 Simulation Builder

Create custom HYROX workouts (e.g., "4K Power Gauntlet") and execute them on your watch. Test race strategies before race day.

📊 Performance Analytics

Breakdown of each station — HR drift, recovery, pacing, power output. See exactly where you need to improve.

💪 For Real Athletes

Technical Architecture

Design: Watch → Kafka → Feature Store → LLM Planner → UI

The planner uses a prompt with guardrails and unit tests (yes, for an LLM) to keep prescriptions sane. Streaming planner with function-calling for station blocks, cached embeddings, budgeted context windows, and end-to-end 99.9% reliability target with retries at the event layer.

What's Next

Native Watch app triggers per segment

More robust threshold estimation from field tests

Advanced station-specific recommendations based on your historical performance
