Blowing up at the wall balls because you went out too hard on run one? That's a pacing problem, not a fitness problem.
ROX-strat builds a personalized Hyrox® pacing plan from your 5K time, your station PRs, and how aggressive you want to race. On race day, an Apple Watch ghost tells you whether you're ahead, on, or behind your plan — segment by segment, all 31 of them. New here? Your first 90 days of ROX-strat Pro are free, no card required.
WHAT YOU GET (FREE)
• PFT onboarding — a personal fitness test that captures your baselines
• Fixed-algorithm Simulator — Riegel formula plus fatigue curves
• Live Race Ghost on Apple Watch — ahead / on / behind, in real time
• Roxzone guide — pacing through every transition
WHAT'S IN ROX-STRAT PRO
• Live Readiness Score — HRV and sleep from Apple Health, read as race-day readiness
• ML Decay Engine — three on-device models predicting how your station times fade early, mid, and late race
• Strava sync — read-only, to pull your training history
• Fatigue Sliders — hand-tune the fatigue curve to your body

HOW IT WORKS
Run the PFT once to set your baselines. Simulate your race across 8 × 1km runs, 8 stations, and the Roxzone transitions — 31 segments in all (Ski Erg, Sled Push, Sled Pull, Burpee Broad Jumps, Rowing, Farmers Carry, Sandbag Lunges, Wall Balls). Then race with the ghost on your wrist.

On-device ML — the three models run on your phone with CoreML, and your raw Apple Health data never leaves it. Sign in with Apple is your login, so there's no separate password. Apple Watch native, with sub-100ms haptics.
