Why COROS Plans Work
Science-Backed Approach
Each COROS training plan is built by certified coaches who apply the latest in sport science to create purposeful workouts. These aren’t generic templates—they’re structured using a periodized approach that guides you through phases of building, recovery, tapering, and peaking. This progression helps you grow consistently while avoiding burnout, so you’re ready to perform at your best when it matters most.
Built for the Half Marathon
Being in “mile shape” is not the same as being in “half marathon shape.” COROS Coaches design each plan specifically to prepare you for the 13.1-mile distance—with workouts that build aerobic endurance and pacing discipline.
Personalized to Your Fitness
Every COROS plan uses your EvoLab zones to scale each session to your current ability. As your fitness improves, so do your workouts—ensuring you’re always training at the right intensity, without needing to adjust anything manually.
