There’s something powerful about showing up to a run each week knowing someone is there to guide you through it. That’s the idea behind 5K with Kori, a new treadmill running series led by iFIT Trainer Kori Sampson inside the iFIT fitness app.
Designed for intermediate runners, this weekly run brings the energy of a run club straight to your treadmill. Each workout centers on a full 5K effort, giving you a chance to build endurance, improve pacing, and stay consistent with your training.
Running a 5K isn’t just about speed. It’s about rhythm, focus, and learning how to manage effort over distance. In this series, Kori coaches you through each run with practical guidance and encouragement so you can stay present in the workout while continuing to progress.

What makes this series unique is its weekly format. Each run is filmed close to its release, helping it feel timely and connected to the running community. Instead of following a static program, you’ll feel like you’re showing up to a fresh run each week alongside your coach within the iFIT running app experience.
Each session is designed to challenge you while remaining approachable for runners who already have some experience under their belt. Whether you’re working to improve your 5K pace, build cardio fitness, or stay motivated toward your fitness goals, these workouts give you a reliable place to start.
Because the series centers on the classic 5K distance, it’s easy to track your progress over time. As the weeks go on, you may notice your pacing becoming steadier, your breathing more controlled, and your confidence growing with every run.
Consistency is where real progress happens. Showing up for a weekly run helps build the rhythm that makes training feel sustainable and rewarding. With Kori guiding the way, you can focus on putting one foot in front of the other, building endurance, and continuing to improve with every run.

Each new run is another chance to show up, challenge yourself, and keep your momentum going.
