Hi, I'm Coach Jenny!

A running and multi-sport coach whose love for athletics lead me to run the Boston Marathon and race all over the world. 

But I didn't start out as a runner. Far from it! 

My goal is to give you easy-to-understand tools and tips that you can use to improve your running and your life.

Why?

Because some time ago, someone invested in me, guided me towards my inner runner, and it changed my life forever.

These days I share my training plans and outrageously fun challenges with awesome people, just like you.

How Did I Get Here?

I never set out to be a coach.

In fact, I was a chubby young woman who hated to run.

What did I know about running? I was a mere running mortal, fresh off of earning a degree in Exercise Science and working in a corporate fitness center.

Coaching found me. 

Employees started asking me to help them train to run for weight loss, to reduce stress and to reach finish lines.

So I scoured the running world to learn more about how to train mortal runners – you know, folks that are trying to balance work, life kids, friends, significant others, pets, shopping, sleeping, eating and oh yea, running.

But all I could find were traditional running formula’s (running 6-7 days per week – lots of miles – really fast).

I learned mortals didn’t want to run every day like the traditionalists. They wanted to do karate, yoga, cycling, skiing, skating, strength training, volleyball, basketball, and aerobics.

So I sat down with them one at a time and created personalized training programs that evolved around their busy lives, their active interests and most importantly, their unique fitness level.

Push yourself to a new level of excitement and adventure!

And you know what? I kind of liked it. I actually loved it. Because it was like figuring out a mystery.

We learned together and I had the pure and utter joy of seeing cool people reach incredible goals they never imagined they could (a.k.a. High Five Moments).

And soon, a handful of people turned into my first training company. And that turned into co-founding Chicago’s largest multi-sport company (Chicago Endurance Sports).

So I branched out and started answering running questions via email for over 30,000 participants at the Indy Mini Marathon, which led to writing a blog on RunnersWorld.com, a column in Women’s Running Magazine and authoring two books.

And every question fueled an expedition to find an answer.

Question by question, I learned what confused you, what inspired you, what hurt you and most importantly, how to guide you.

So I kept answering your questions, and together, we paved the way to a new paradigm of running. A world that included realistic workouts, easy to understand words and training regimens that were fun, effective and didn’t require you to abandon your family.

And along the way, I found my coaching voice, my writing voice and my passion in life–my sweet spot.

Thank you for that.
