Individualized Endurance Coaching

Triathlon - Cycling - Running

Athlete Driven Endurance Coaching

Triathlon based in the United States.

There is more to training than just the plan. While each plan is uniquely designed for each athlete and their goals, we take a deeper dive into the journey by also focusing on nutrition, hydration, race planning, and balancing it all with work and family.

Each athlete can expect a high level of communication, a coach that is 100% invested in their success, and a new community to enjoy.

Who Is Sarah Portella?

I am an endurance coach (triathlon, run, cycling) with Bolton Endurance Sports Training (B.E.S.T.) based in Nashville, TN. My goal is to provide the highest level of coaching to every level of athlete.

By placing value on two way communication and focusing on progress both great and small, I can help my athletes meet their goals and increase their love of the sport.
