Power Metrics
Enter your weight and pace to estimate power.
Overview
Running power is the measure of the mechanical work done while running. It provides a real-time assessment of effort that is more responsive than heart rate.
💡
Pro Tips
Running power is highly sensitive to changes in gradient.
Lower energy cost (better efficiency) is often found at slight downhills.
Wind resistance and surface terrain also affect actual power required.
Use power metrics to pace climbs more effectively than using pace alone.

Fun Facts
"A 10% incline can double the energy requirement compared to flat ground."
"Elite runners often maintain 5.5 - 6.5 W/kg during championship races."
"Running power meters often use accelerometers to estimate force and vertical work."
Formula: Minetti et al. formula for grade-adjusted energy cost.
