Half Marathon | 12-Week Beginner Confidence Plan
Stepping up to a half marathon is a major personal challenge. Many beginners feel uncertain about how to build distance safely or fit training into a busy career. This 12-week program provides a professional framework to build the stamina needed for the 21.1km distance.

Every hour you spend training helps you feel more prepared for race morning.
