How to use Running Training Pace Zones
Running training zones divide effort into intensity ranges, often based on pace, heart rate, or perceived effort.
Basic idea
Reference pace or heart rate x zone range = training target
Are running zones based on pace or heart rate?
They can use either. Pace is direct, while heart rate reflects internal effort and can change with conditions.
