The Riegel model uses an exponent of 1.06. It assumes a gradual slowdown as distance increases, not a guaranteed result.

Estimates are indicative. Longer races in particular depend on endurance, fueling, conditions and distance-specific training.

You have the pace. Now build the plan to reach it.

Pacero combines your goal, training, load and recovery into a plan that responds to reality.

HOW TO USE THE RESULT

Pace is a number. How you use it makes the difference.

01

How to work with pace

Treat target pace as an average guide. Practise it in shorter controlled segments rather than trying to hit it on every run.

02

How to use race splits

Watch the opening kilometres and avoid starting too fast. Consistent splits leave more energy for the closing stages.

03

When a goal is realistic

Compare the goal with recent performances, training volume and long runs. The calculation shows the required pace; training shows your readiness.

04

Why target time is not enough

Training load, recovery, course profile and weather all affect the result. A sensible plan builds performance gradually without chasing mileage.
