“Now, I genuinely believe I can do it.”

Justine started her first-marathon journey feeling intimidated by 26.2 miles. Personalized training, weekly check-ins, and adjustments helped her become a stronger, smarter runner—and trust her ability to finish.

In their own words

Progress is more than a finish time.

It can mean trusting your body again, understanding your training, becoming consistent, or finally believing a big goal is possible.

When I started working with Coach Greg, the idea of running a full marathon—my first one—felt pretty intimidating. Now, I genuinely believe I can do it. The confidence I have in my training and in myself is something I didn’t have before.

Justine highlighted Greg’s attention to detail, personalized training, weekly check-ins, and ability to adjust her workouts when needed.

Coach Greg is an educated, mindful, and personable coach. I walked into his gym ready to commit but afraid of re-injuring myself. With his guidance, I’ve been back into the workout scene and gaining more confidence and strength each day.
