Why Duathletes Choose Athletica

Athletica synchronizes your bike and run training with real-time data and recovery metrics—automatically adjusting intensity to keep you building fitness, not fatigue.

The result: Consistent progress, stronger transitions, and peak readiness when it matters most.

Built for every athlete

Beginner

Build endurance and confidence across both disciplines. Learn how to pace transitions and recover efficiently between efforts.

Intermediate

Sharpen power, pacing, and run-off-the-bike control with progressive intensity and data-driven balance.

Advanced

Target peak race readiness with specific brick sessions, taper protocols, and course-tuned workouts for sprint, standard, or long-distance events.

Missed session? Extra fatigue? Athletica recalibrates automatically. No guilt—just progress.

How It Works

Adaptive AI Planning

Your plan updates daily based on heart rate, power, RPE, and recovery. Push a breakthrough session and tomorrow adjusts upward. Need rest? Your load rebalances instantly.

Intelligent Brick Integration

Duathlon isn’t just bike + run—it’s the transition between them. Athletica structures brick workouts that simulate real-race rhythm, training both legs and lungs for efficient switchovers.

Periodized For Peak Performance

Plans follow evidence-based endurance principles: base → build → taper → race. Each block fine-tunes aerobic fitness, muscular endurance, and metabolic efficiency to peak on race day.

Intelligent Coaching Meets Seamless Integration

Sync your Garmin, Strava, Coros, Wahoo—or any preferred tracker. Every session feeds into insights that elevate your training. This isn’t just a training plan—it’s a responsive coaching system.
