Build Aerobic Base Safely with Structured Walk Breaks

The run-walk method (pioneered by Olympian Jeff Galloway) allows runners of all fitness levels to build endurance, prevent overuse injuries, and manage fatigue by inserting planned walking intervals.

This running interval timer alternates clearly between run (red/green) and walk (blue) periods with audible high-pitched and low-pitched cues so you know when to accelerate and when to ease into recovery.
