Coaching built for real life

You don’t need another generic training calendar.

You need a plan that responds when work gets busy, weather changes, a workout goes poorly, or your body needs a different approach.

You’re preparing for your first half or full marathon.

You’ve followed plans before but struggled with pacing, consistency, or recovery.

You want to improve without treating every run like a test.

You need accountability and clear adjustments when training doesn’t go perfectly.

The Race Ready Run System

Every part of race preparation, working together.

Running is the foundation. The details surrounding it determine whether you can consistently absorb the work and arrive prepared.

01

Personalized run training

Easy runs, quality sessions, long runs, and race-specific work progressed around your fitness, schedule, and goal.

02

Strength and mobility

Runner-specific work that supports durable mileage without leaving you flat for the runs that matter.

03

Fueling and recovery

Practice hydration, long-run fueling, daily nutrition, and recovery habits before race day exposes the gaps.

04

Weekly accountability

Review what happened, make smart adjustments, and keep one difficult day from derailing the entire build.

“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.”

Meet your coach

I’m Greg Barber.

I’m an ACE-certified personal trainer and running coach with more than 10 years of experience. I help everyday runners turn an intimidating race goal into a clear weekly process they can consistently follow.

You don’t need elite speed or unlimited training time. You need honest feedback, a plan that fits your life, and a coach who knows when to push—and when to adjust.

Common questions

Before you apply.

Do you coach first-time marathon runners?

Yes. Your build starts from your current ability and coordinates mileage, pacing, long runs, strength, fueling practice, recovery, and race-day preparation.

Is this coaching completely online?

Yes. Online coaching is available nationwide. Your plan, check-ins, feedback, and adjustments are designed to give you personal support wherever you train.

What if my schedule changes or I miss a workout?

That is exactly why personalized coaching matters. We adjust the plan around real feedback rather than forcing you to make up every missed session.

Do I need to be fast?

No. Coaching is built around your starting point—whether you’re learning to run continuously, preparing for your first marathon, or pursuing a new personal best.

Is strength and fueling included?

Yes. Runner-specific strength, mobility, fueling, hydration, recovery, and race-day strategy are integrated with your run training.
