Mark Minichiello

Marathon Career

When you run your first marathon, you will either catch the fever or it will be your first and last. Mark found his passion in marathon running and never looked back. He started his marathon career as a member of the LA Road Runners, the official training program of the Los Angeles Marathon. For Mark, it became one of numerous marathons spanning multiple countries on two continents.

After completing his tenth marathon, Mark decided to pay it forward by inspiring others when he became a pace leader for the LA Road Runners. Mark went on to become a senior pace leader for the LA Road Runners, and he is now the LA Road Runners Program Coordinator for the 2016-2017 season. Mark is proud to be a LA Road Runners Program Coordinator for the organization that not only trained him for his first race but also taught him he can achieve the unimaginable.

Coaching Career & Philosophy

Mark is a Boston Qualifier, a USATF Certified Coach Level 1 and an RRCA Certified Endurance Coach. He coaches with the South Bay Runners Club in Los Angeles, where he coaches track and marathon training sessions. His goal over the course of his running career has been to inspire other athletes. This is what first brought Mark to coaching.

Mark believes training is fifty percent physical and fifty percent mental. It is his job to define the objective of his runners, analyze their results and provide constructive feedback. As a coach, Mark provides the runner with his expertise by explaining the “why” with the goal of empowering the runner to train optimally. He tries to instill the power of belief, so when his runners are truly tested, they believe in their ability to accomplish their goal. Mark believes this approach will sustain them in their darkest moments when they want to quit. The time and effort required to achieve such mental strength is immense but truly rewarding. Steve Prefontaine said it the best, “To give anything less than your best is to sacrifice the gift.”
