Falsches Pacing auf der Ironman‑Radstrecke

Der Fehler, der deinen Lauf ruiniert

 

IF range

Zone label

What it means for your race

< 0.60

Too easy

Fine for the opening 20–30 minutes in controlled conditions. Not sustainable as a race strategy — you will lose time without reducing run fatigue meaningfully.

0.60–0.70

Endurance / foundation

Appropriate for athletes targeting finishing, or in extreme heat. Minimal run compromise.

0.70–0.76

Target race zone

The sweet spot for most age-group athletes. Sustainable with appropriate training, manageable run fatigue.

0.76–0.80

Caution zone

Possible for strong cyclists, but requires excellent fitness and near-perfect execution. Margin for error shrinks significantly.

> 0.80

Danger zone

Almost certain to compromise the run for age-group athletes. Feels strong early; the run will reveal the cost.
