1-on-1 Online Physical Therapist + Running Coach + Nutrition Coach for Weight Loss

Hi, I'm Dr. Casey Guthmiller - Doctor of Physical Therapy (DPT), UESCA Certified Run Coach, Precision Nutrition Level 1 Coach, and the Founder of Running4U LLC.

I help complete beginner to intermediate runners lose 15-30 pounds, build consistent running habits, and stay completely injury-free through highly personalized 1-on-1 online coaching.

More importantly, I am a follower of Jesus, husband to Sarah, and proud (sometimes tired) new dad to Rosie. You probably know me from social media (@r4ucoaching) where I share regular running tips for beginners.

My own journey with running began when I decided to give it a try in 2017.

I thought it was simple.

Put shoes on. Run. Repeat.

However, I was *delightfully* met with constant injuries, fatigue, and inconsistency. I struggled with a lack of motivation to get out the door, was making little to no progress, and felt discouraged by how hard it was to build positive momentum in my running.

It wasn’t as simple as I’d hoped!

As I was in physical therapy school at the time, I refused to accept this as normal. I went on to devote years to understanding the science of running, combining my expertise in physical therapy with the latest run coaching practices and strategies. I experimented with different approaches, studied the latest research, and applied this knowledge to my own running.

It was only after this that my running took off.

Less than six months later, I ran my first full marathon with zero injuries - a feat I certainly never thought was possible for someone with my injury-prone history.

Going through this process, I realized I had something special. I gradually started to coach runners one-on-one in 2020, and was ecstatic to see they were having the same success that I was.

Fast-forward to today, and hundreds of new runners have experienced this same success.

This led to the creation of my app, the R4U Running Club. It contains the exact programs, methodology, and support that I wish I had when I started. 

With it, I would have saved years battling injuries and lack of progress - and replaced it with positive momentum in my running.

As my working career has progressed - the more I learn, the more I realize how everything is connected.

Running, nutrition, strength work, stress management, sleep, recovery.

Best results only come through unifying all these variables in unique alignment to your life - your goals, life schedule, eating preferences, equipment available, etc.

This cannot be accomplished without a highly individualized approach.

Considering that many runners come to me with a primary goal of weight loss, all of this naturally led me to create The Runner's Weight Loss Transformation. It is a 16-week, high-touch coaching experience dedicated for those who want to lose 15-30 pounds, build their running, and stay injury-free along the way.

It combines everything I've learned as a Physical Therapist, UESCA Run Coach, and Precision Nutrition L1 Coach - alongside my experience coaching hundreds of runners over the years - into one system.

For a quick peek behind the veil - working with clients within this program is the most aligned I have ever felt in my professional career. I absolutely love it.

If you're ready to get your health and running on track, I would love to talk more about what it would look like to work together within this program. You can apply here and book a call to learn more.

That's my story! Thanks for being here.
