Choose a theory that fits your goals and style from world-proven training methodologies.
Pace-score driven. 5 zones × 4 phases for systematic progression.
Marathon-focused. Pace + HR dual control with progressive volume build.
80% low intensity, 20% high. Strict zone management based on LTHR.
Cumulative fatigue model. Designed around race-pace adaptation.
Double threshold sessions to shift the lactate curve. HR-based intensity.
Ultramarathon-specific. Block periodization + mountain passes + priority management.
Mountain trail-specific. Aerobic threshold base + elevation gain management + 3% rule.
