Certified Personal Trainer, NCCPT; Level 1 Certified Coach, USAT 

Having raced on an elite level for 15 years, T4 Endurance Co-owner and Coach, Nathan Kark is no stranger to training and all things swim, bike, and run. Within his 15 years as a multisport athlete, Nathan has conducted seminars for age group and collegiate athletes throughout the USA Triathlon (USAT) Mid-west and Mid-east regions. A recent law school graduate, Nathan has also maintained his level of fitness and competitive edge throughout the scheduling demands of law school and as a busy legal professional. He is a seasoned expert in helping each of his athletes train effectively while balancing a busy lifestyle.

"Your typical multisport athlete has more drive and determination in their pinky finger compared to the average person. This drive and determination, if harnessed correctly, can propel people to greatness but can also spread people too thin. It is my passion to provide athletes with purpose-driven training to maximize efficiently, allowing them to enjoy all aspects of the life they want to live. Learning what each athlete needs to perform at his or her very best and incorporating this into a personalized training program that includes, not simply a training plan, but real, hands-on guidance on how to incorporate triathlon into a busy lifestyle is critical for optimum performance."

As a coach, Nathan strives to separate T4 Endurance from other coaching services. T4 Endurance offers nothing but custom-tailored and innovative coaching solutions that are specially designed to meet the needs of its clients. Through his coaching plans, Nathan provides detailed guidelines, while also helping his clients understand why each workout will make personal goals attainable.

Coach Nathan has raced and coached at all distances that triathlon has to offer. He has competed on a national level and qualified for USAT Worlds. His biggest athletic accomplishment however, is watching his athletes surpass their expectations and knock down personal barriers. Whether working with beginners, experienced age-groupers, or elite triathletes, Coach Nathan brings to each individual a knowledge for the sport of triathlon and a contagious passion to motivate athletes to reach their potential.
