Why You Need a Structured Plan

Trail and ultramarathon races require strategy, patience, and the ability to adapt to changing terrain, elevation, and fatigue over long durations. Without a structured plan, it’s easy to overlook critical elements of training, overreach early, or neglect recovery. That’s where COROS training plans come in. Designed specifically for endurance athletes, these plans help you build sustainable volume, train with purpose, and arrive at the start line prepared for the unique challenges of your race.

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. COROS plans are 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 Trails
Being in “marathon shape” is not the same as being in “ultra-trail shape.” COROS Coaches design each plan specifically to prepare you for the target distance—with workouts that are designed for the trails.

Personalized to Your Fitness
Every COROS plan uses your EvoLab zones and Effort-Pace 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.
