I’m Coach Greg, the coach behind GTB Performance. I help runners prepare for their first 5K, build toward a half or full marathon, and work toward a new personal best with a plan that fits their starting point, goals, and schedule.
With over 10 years of coaching experience, I take the time to listen and understand what you need.

Greg is excellent!. I've never had a running coach. I used to run only 5 and 10Ks years ago. Got back into running in the last 6 months and signed up for 10 Disney races over 4 months that include half and full marathons. I figured I might be a good idea to do this a better way! I looked at a few dozen coaches and Greg stood out. Not only did I feel confident that he could coach me with the injuries I've had and with running as an older runner, I felt he would really give me personalized attention rather than a "cookie cutter" training program I saw with many other coaches. He is very low key and really listens to what my experiences have been to adapt my training. My first 3 races are in a month and I feel very prepared because of Greg. I can't wait to see what's to come. More...

I came across a questionnaire on social media that connected me with Coach Greg, and honestly, I had no idea at the time how much that one decision would change my running. Working with Coach Greg has taken my running to a completely different level. His knowledge, attention to detail, and ability to tailor my training to me and my goals have made such a difference. He challenges me, pushes me beyond what I thought I was capable of, and at the same time, teaches me to trust the process and listen to my body.The biggest change though, has been my mindset. When I started working with Coach Greg, the idea of running a full marathon, my first one, felt pretty intimidating. I have only run half’s and always wanted to run at least one full marathon in my life, but running 26 miles was just daunting. 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, and a huge part of that coms from having Coach Greg in my corner.He has helped me become a stronger and smarter runner, and I’m seeing progress that I never expected. I ran 18 miles just the other day and thought it wasn’t too bad.. really!?!! Every workout has a purpose, and every step forward has made that marathon goal feel more realistic.I’m incredibly glad that questionnaire led me to Coach Greg and very grateful. What started as a random opportunity on social media has turned into one of the best decisions I’ve made for my running. I’m excited to see where this journey takes me and, most importantly, I finally feel like I’m ready to take on that first marathon.If you’re looking for a coach who will challenge you, support you,and help you believe you’re capable of more, I highly recommend Coach Greg.

I have trained with Greg Barber through FITT for Change for four months and 16 days now. My entire body started changing after the first week. Greg has tailormade complete schedules and "circuits" to mesh with my strengths and weaknesses. I have lost ~9 inches at my natural waist, and nothing fits anymore; I've gone from wearing 4XL t-shirts (in men's since I couldn't find them in women's), to wearing Large and XL. My stomach has shrunk; my legs are smaller. My stature is even getting smaller! Several people have complimented me recently on how I look and what I've been doing. The "Change" part of this business name is spot on. Fitt is still spelled wrong. More...
How do you help your clients achieve their fitness goals?
We start with your goal, current training, schedule, and any challenges that have made progress difficult. For runners, I build a plan for distances from the 5K through the marathon, combining running workouts with strength, mobility, pacing, and fueling guidance.
Regular check-ins and feedback help us make adjustments when life gets busy or training needs change. You’ll understand the purpose of your workouts and learn how to train at an effort you can sustain. For general fitness clients, we use the same step-by-step approach to build strength, improve movement, and develop consistent habits.
What’s the secret to getting the body of your dreams?
The secret isn’t a perfect workout, extreme diet, or quick fix. It’s having a realistic plan you can consistently follow.
That means combining strength training and cardio with balanced nutrition, proper sleep, and recovery. Your program should match your goals, experience, lifestyle, and starting point—and progress as you improve.
The “body of your dreams” will look different for everyone. The real goal is to build a body that is stronger, healthier, moves well, and gives you confidence. Consistency, patience, and accountability are what create lasting results.
What do you love most about your job?
I love seeing clients build confidence as they make progress. Watching someone become more consistent, complete a workout they once found intimidating, or feel ready for their first race is one of the most rewarding parts of coaching. I’m grateful to be part of that journey.
What inspired you to start your own business?
Business and fitness are my two biggest passions, so starting my own coaching business made sense. It gives me the opportunity to work directly with people, understand their goals, and help them build healthier habits one manageable step at a time.
Why should our clients choose you?
You’ll work directly with me, Coach Greg. I bring over 10 years of coaching experience and take the time to understand your goals, training background, schedule, and concerns.
For runners, my Race-Ready Run System connects personalized pacing, fueling, and strength and mobility. We build a plan around your starting point and use check-ins and feedback to adjust it as you progress.
My goal is for you to feel heard, understand your training, and build confidence in what you can do. Whether you’re preparing for your first race or working toward a new personal best, we’ll focus on consistent progress that fits your life.
Can you provide your services online or remotely? If so, please add details.

Your workouts are delivered through Trainerize so you can follow your plan on your own schedule.
