Dermott Hayes’ Endurance Brick #1 pairs disciplined aerobic riding with controlled progression on the run. After a steady 40km ride at Level II, the challenge is shifting gears smoothly and building through 2km at Level III before pressing into Level IV — finishing strong without forcing it. A simple structure that strengthens both your engine and your composure.

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.
