Beth's Story

When Beth set out to run the Philadelphia Marathon in 2017, she had the ambitious goal of a 3:35 Boston Marathon qualifying time. Unfortunately, she crossed the finish line in a disappointing 3:45.

Taking stock of what went wrong, Beth determined her current training methods weren’t cutting it. She turned to Run Your Personal Best for help, and five months later, she ran her dream race: a Boston Marathon Qualifying time of 3:31.

Since then, Beth has stuck with her coach's plans, hitting shiny new PRs at every distance from the 5k to the marathon. The physician and mother of three have done it all while working full-time as a medical director at multiple facilities.

While Beth’s story may differ from yours, we all share the same sense of joy and accomplishment when running confidently - no matter your ability. It carries over to all aspects of your daily life. You approach every new day with a sense of vigor and optimism.

Why Work With Us?

We understand that running may not be your first priority in life, but that doesn’t mean it isn’t important to you. You're eager to improve and willing to work hard to do so.


Great coaching is all about meeting you where you are, as both a runner and everyday parent, spouse, professional, or friend, and then designing a running program that fits with not only your lifestyle but also your experience level.


Training should be challenging but not break your back. Your workouts should motivate you, not scare you. Helping you run faster is more than just prescribing workouts. It’s about encouragement, feedback and guidance.


Based on this philosophy, we’ve developed a system that works to get you faster while helping you run longer, stronger, and more confidently, and we have the testimonials to prove it. This customized approach is just a piece of what sets Run Your Personal Best coaches apart from the rest.


Unlike many other running coaches, this isn’t our side gig, it’s our main gig.  Our coaches have devoted a large part of their lives to learning and excelling in the art of running.  Coaching isn't just our career, it's our passion.


No matter what type, age, or ability level runner you are, we’re here to meet you where you are today and take you beyond where you want to be. We are dedicated to your success 24/7.
