Why do “Bricks” need to be incorporated in a training program?
Triathlon is a sport of its own, not just a combination of three separate disciplines, which means it needs to be treated as such in training by including sessions that incorporate more than one sporting discipline. Cycling after swimming is not the same as cycling on its own, and the cycling leg of a triathlon impacts the way you run. Your body needs to be able to effectively and efficiently prepare itself for the next demand (different muscles, different posture, etc.) and then recover from and forget about the previous task. Brick workouts help you get used to this dynamic, and also train your body to handle the aerobic, anaerobic, and muscular demands that you will experience during these important parts of the race.
