Glossary: Grade adjusted pace (GAP)
Grade Adjusted Pace estimates your equivalent pace at the same effort on flat ground. For running up hill, grade adjusted pace will be faster than your actual pace and for down hill it will be slower.
The calculation of Grade Adjusted Pace highly depends on your elevation profile. For accurate results it's required to have barometric data.
