Coaching Bio
Dr mark McCullough

As a coach, I want to help prepare the mind to enjoy race-day and to be confident in instead of being a bundle of nerves....taking on the attitude that “I get to do this”! My vision for my athletes are for them to be fit and balanced for as long as they want to participate in endurance sports. My hope is to pay it forward to my athletes from my personal experience.

Dr. Mark is a coach, triathlete, and an Amazon best-selling author that is based in Toledo. Dr. Mark developed his passion for triathlon after many years as a swimmer and late diagnosis of Type 1 diabetes. This diagnosis revved up his pursuit to not only become the healthiest version of himself but also to become a mentor and coach to help those committed to being their best.
Continuous improvement is Dr. Mark’s mantra in life as well as sport. Those who try and fail successfully will attain and achieve greater success in whatever they set their mind to. He incorporates this philosophical style into his coaching and relationships in hopes to come alongside and bring out the best he he leads. Consistency and connecting inspires and assists individuals in meeting and achieving his/her goals which will spill over and impact their entire life.

Future events:
The Tristar Athletes race fueling consult is one of our most popular services we offer. We will craft a plan that addresses your nutrition limiters and prepares your body for any endurance event.
Every athlete has distinctly different nutritional needs for optimal performance. We use the latest scientific research to provide athletes of all levels with individualized nutrition plans based on their unique performance and fitness goals. We consider individual training schedules and lifestyle choices to determine specific energy and hydration needs for each athlete and maximize energy levels. This expert analysis and individualized nutrition plan improves endurance and speeds muscle recovery.
The plan developed by our coaches will address your carbohydrate, fluid intake and sweat loss / electrolyte replacement strategy. This consultation is the starting point for our Tristar Nutrition Coaching.
Your nutrition plan will be developed by our principal level III coaches or certified nutritionists. You will receive a detailed caloric and nutrient based plan (PDF / Spreadsheet) with your key event from start to finish. You will setup a call time with your Tristar team to go over your current health histories and what has worked or not worked for you in the past.
