The Importance of Aerobic Threshold Training

Aerobic threshold training, often thought of as the gray zone between easy and high-intensity efforts, is vital for improving running performance. This intensity allows runners to sustain efforts that mimic race conditions, facilitating adaptations critical for long-distance events. Rather than being considered junk mileage, this training helps enhance metabolic efficiency, ultimately enabling runners to maintain target paces over extended periods. Incorporating structured workouts in this domain can be crucial for runners of varying abilities, from beginners to advanced athletes.
