Use the Numbers as a Guide

Pace, heart rate, race predictions and training data can all be useful, but they need context. Fitness, fatigue, terrain, weather and the purpose of a session can all affect what the right effort looks like on a particular day.

A useful starting point, not a prescription.

These free running tools and guides are designed to help you understand your training. They cannot account for everything that makes you an individual runner or replace personalised coaching built around you.
