California Running Lab is run by Aleks Gradinarova, an RRCA Level II adult distance running coach, USATF Level I-certified coach, and a Certified Personal Trainer (NASM) in Silicon Valley, Calif. 

I’m a mother, runner, and triathlete who has been living and loving the running life for 20+ years. In 2015, I launched my coaching business because I realized that my passion to help others achieve and exceed their goals as runners and athletes was just as strong, if not stronger, than my own dedication to always improving and evolving myself as an athlete. Since then, I have been coaching runners of all levels, from those training for their first half marathon or coming back from injuries to complete a 5K or 10K, to runners training to run a BQ marathon or ultra marathon events.

My motto for myself and my athletes is “Train with Purpose, Race with Heart,” and my goal is to develop the ultimate smart, individualized training plan for their needs, based on their running history, schedule, strengths, weaknesses, goals, and life.
