Faye and Jess have created custom strength and run programs and provided coaching mentorship to hundreds of runners and OCR athletes. This is the bread and butter of Grit Coaching, and we love working one-on-one to help our clients reach their athletic goals.


However, we've noticed that there is a substantial group of runners who want some type of strength training to help their running and round out their athleticism, but they don't necessarily need or want a full-on custom program at this time.


Unstoppable: Strength for Runners is designed to bridge that gap. We've put our coaching expertise into a self-directed app, making strength training accessible and affordable.

Each workout takes approximately 30-40 minutes.

The first time you do a new program will likely take a bit longer as you become comfortable with new exercises.

UNSTOPPABLE is designed to be done at home with minimal equipment.  Tools we'll use include:

  • A miniband (these are very inexpensive and can be purchased online, at most physio/pt/chiro clinics, or many sports stores)
  • Small towel
  • Backpack with books in it
  • Milk jug filled with water or gravel (or dumbbells/kettlebells)

The program is delivered through our app. Each month includes an intro video with an overview of the purpose of the exercises that month.

The app has videos and written descriptions of every single exercise.

You are able to track sets, reps, and notes about your workouts in the app. You are also able to film yourself and assess your form directly in the app!


Research shows that the best way to get conditioning adaptations is progressive overload: hit your body with something new, progress, and then switch things up to challenge your body in a new way.


Each monthly program contains two different workouts to be done during the week, repeated weekly for four weeks.


Though the exercises remain the same for four weeks, the VOLUME changes weekly - you'll add sets, reps, or weight to keep yourself challenged as you get stronger.


It takes time to get comfortable with new exercises and get the most out of each movement. You don't want to get toooo comfortable though - that's why it's important to switch things up regularly, but not every day.

Each month, you'll recieve fresh exercises. Each program will have the same general components (mobility, stability, strength, and core), but some months will have special focuses such as breath work and foot-specific strength.


The program is progressive and generally (though gradually) becomes more difficult.

Coach Faye in 'GRIT' athletic attire confidently poses with crossed arms.

Faye’s journey in athletics is marked by dedication and impressive achievements. Throughout her high school and university years, she was deeply engaged in running, competing for the University of Calgary’s track and cross-country teams. Her standout moments include earning the “All Canadian” cross-country status and participating in the 2008 Olympic trials for the 5000m. After obtaining her Bachelor’s degree in Kinesiology, Faye embarked on a career as a personal trainer, where her passion for fitness and a healthy lifestyle became a source of inspiration for her diverse range of clients.

Transitioning from competitive running, Faye soon discovered her next athletic passion: obstacle course racing (OCR). Her strong foundation in running and strength training quickly propelled her to success in the OCR world. Faye’s talents were recognized in 2016 when she joined the Spartan Pro Team, and her athletic ability was furthered with a bronze medal at the Spartan World Championships.

Continuing to compete among the elite, Faye has consistently demonstrated her skill and tenacity in OCR. She has secured two 4th place finishes at both the Spartan North Americans and the Spartan World Championship. Her record of Spartan podium finishes over the past decade showcases her enduring excellence in the sport.

Beyond the thrill of competition, it’s the OCR community that deeply resonates with Faye. The opportunity to travel, share her passion for fitness and adventure, and connect with an array of positive, inspiring individuals fuels her year after year. Faye embodies the essence of the “work hard, play hard” ethos, living it to the fullest in both her professional and personal life.
