MidLab — Middle-Distance Training, Scientifically Optimized
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.
