The training management app built exclusively for 800m-5000m middle-distance runners.
■ Measure Your Fitness with the ETP Test
Run our unique ETP (Estimated Threshold Pace) test on a 400m track to accurately determine your threshold pace. MidLab also classifies your performance limiter into three types:
• Cardio Limiter — your breathing hits the wall first
• Muscular Endurance Limiter — your legs give out first
• Balanced
■ Personalized Training Plans [Premium]
Based on your ETP and limiter type, MidLab auto-generates a multi-week training plan tailored to your goal race. Scientific periodization — Base > Build > Race > Taper — helps you improve efficiently.
• Just set your target race distance and date
• Supports 800m / 1500m / 3000m / 5000m
• Optimized for your age category and training history
• Automatic recovery weeks
■ Extensive Workout Library [Premium]
Dozens of workout templates organized across six training zones (Recovery through Repetition). Every pace is auto-calculated from your ETP so you always train at the right intensity.
■ Race Predictions
Estimate your 800m-5000m race times based on current fitness. Compare against your personal bests to see your progress.
■ Dashboard
• View your current ETP, VO2max, and limiter type at a glance

• Track weekly progress
• Follow your ETP trend graph to visualize growth
