Glossary: Climb Score
RUNALYZE categorizes all climbs in your activities and analyzes them, from little hills of the 5th category up to mountains of 'Hors catégorie' (HC). The classification is based on the FIETS index, that uses length and gradient profile to calculate a single number for each climb.
All climbs – no matter whether they are classified or not – are used together with the percentage hilly to calculate an overall score for the activity, the so-called 'Climb Score'. This score rates how challenging the course was as a single number between 0.0 (completely flat) and 10.0 (very demanding mountain stage).
