Ironman 70.3 training

What Is a Brick Session and Do You Really Need Them?

A brick session combines two disciplines back-to-back, usually cycling followed by running. Learn why brick workouts are valuable for Ironman 70.3 training, how they prepare your body for the bike-to-run transition, and when to include them in your programme without adding unnecessary fatigue or compromising your overall training consistency.

Although you are unlikely to race an Ironman 70.3 or Ironman at Threshold intensity (by definition it is impossible). Training sessions can use Threshold intensity to build you fitness, and in the same method as a rising tide lifts all ships an increase in your threshold intensity will also lift your overall fitness allowing you to race at a faster pace or higher intensity; or at the same pace or power for less effort. This is a perfect session for triathletes competing in Ironman and Ironman 70.3 distance events.
