YOUR PERFECT HALF
Referring to a 70.3 IRONMAN as a “half” can be misleading because it suggests a short event. But a race that takes between 4 to 8 hours to complete is anything but short!
That’s why properly pacing an IRONMAN 70.3 can be so difficult. In this article the founder of MyProCoach Phil Mosley shares his method for guiding athletes to optimal performance.
His secret is to base the effort of each phase of the race on intensity and, more specifically, as a percentage of threshold power or heart rate. Other than the first 300m of the swim, your aim is to perform at a steady, consistent effort throughout. Here’s how he does it.
By sensibly pacing your 70.3 from the beginning, you avoid going into the “red zone” and set yourself up for running to your potential for a fast finish (which, for most triathletes, will be similar to your full marathon pace).
