Individual attention and training from experienced athletes.

Endure It! Personal Coaching

Our Personal Coaching department aims to help every athlete reach their finish line. We develop real-life plans that work, turning dreams into actionable goals.

Athletes who are ready for personal coaching start with a personal consultation with our Head Coach, Sara Fix, to discuss athletic backgrounds and overall goals. From there, we’ll match you with a coach who best fits your needs.
