RoxSIM

RoxSIM is the first race simulator built for HYROX and DEKA athletes. Simulate full events with accurate run/station splits, real-time pacing guidance, transition enforcement, audio coaching, fatigue tracking, and performance analytics—so you train like race day, not guesswork.

Prepare for HYROX and DEKA formats (Strong, Mile, Fit) with realistic simulations of run segments, sled push/pull, burpee broad jumps, row, SkiErg, AirBike, farmer’s carry, wall balls, lunges, med-ball work, and transitions. Get prompts like “Slow run pace 8%” or “You’re 10s ahead of last DEKA sim” to keep you on strategy.

Core features

HYROX & DEKA race simulations (Strong, Mile, Fit)

• Real-time pacing guidance & audio coaching
• Precise run/station split tracking & race time prediction
• Fatigue/efficiency modeling and transition timing
• Custom simulation builder & training history
• Strategy planning: identify weak segments, balance strength vs endurance

Why it matters

• Train with exact race structure: loads, sequencing, pacing, fatigue patterns
• Enforce transitions (no cheating) and manage energy like on-course
• Improve where you actually lose time, not with random workouts

Built for

• HYROX athletes, DEKA Strong/Mile/Fit competitors, hybrid fitness racers, coaches, and anyone who needs a true race simulator instead of a basic timer.

Any setup, anywhere

• Gym, studio, garage, or limited equipment - RoxSIM adapts. Simulate sleds, carries, wall balls, and runs with alternatives so you can prep anytime.

Stop guessing readiness. Start training like you’ve already seen the course. Download RoxSIM and get race-day ready every day.
