Triathlon Brick Training: Transition Physiology & Neuromuscular Adaptation

In triathlon training, every novice athlete encounters the bewildering sensation of T2: dismounting the bicycle and attempting forward locomotion with legs that feel like lead or jelly.

Brick Training (Bike-to-Run conditioning) bridges this multi-sport physiological gap. Understanding motor unit firing alterations and local hemodynamics transforms chaotic transitions into seamless running efficiency.

Section VI: 12-Week Periodized Brick Training Progression Model

Structured progression from neurological adaptation micro-bricks to race-specific multi-hour simulation sessions.

Section VII: Common Brick Training Pitfalls and Neurological Fatigue Recovery

Expect a 10-15 sec/km pace delta off the bike. Immediate post-brick myofascial stretching restores motor unit excitability.

Section VIII: Pre-Brick Dynamic Activation Protocols

Mobilizing the hip capsule and executing high-frequency neural strides primes the neuromuscular junction for multi-sport loading.

Section IX: In-Depth Brick Training FAQ

Cardiac drift of 5-10 bpm off the bike is physiological normal due to thermoregulatory strain and local blood redistribution.
