=====================================================
★ This application is designed to prepare users to complete a full half marathon (13.1 miles / 21 km) utilizing a structured run/walk strategy ★
=====================================================
The comprehensive 14-week plan is tailored specifically for novice or beginner runners aiming to train for a half marathon. Its run-walk approach helps newcomers mentally segment the race into manageable parts, making the challenge less daunting while minimizing impact and reducing injury risk. The walk breaks serve as mental relief points and aid muscle recovery during training and racing.
Contrary to assumptions that walking might slow progress or lessen achievement, many experienced runners have reported achieving personal best times after adopting this method. By balancing running and walking ratios, runners can better manage fatigue levels, conserve muscle resources, and boost confidence for the race’s final stages.
This gradual build-up enhances endurance and strength while reducing injury risk. By completion of the program, users will be fully prepared to successfully finish their 13.1-mile race.
The app’s audio guidance system facilitates an effortless experience—simply activate our acclaimed music playlist and press start; our voice coach will guide you through each session seamlessly.
