Aaron Whitley is the owner and head coach of E3 TRI. 15 years ago he would have never dreamed of that first sentence in his bio but while searching for a better version of himself and a healthier lifestyle he found endurance sports. Aaron began his endurance athletic career in 2010 with marathon training where he completed 3 marathons. He then was introduced to triathlon in 2012. While training to complete triathlons of various distances, he fell in love with the sport of triathlon. Over the next couple of years, Aaron competed in distances from Sprint to Ironman. While coaching, Aaron discovered his true passion of helping others achieve what once seemed impossible.
Aaron loves working with athletes of all experience levels, from the basic beginner to the seasoned athlete, and helping them reach their milestones and achieve goals within endurance sports. He believes in a true work/sport/life balance in his personalized training plans and believes you can achieve what you set your mind to. This is his true passion in life and would love to talk with you about your goals and turning what you might currently see as impossible into Possible.

Trent comes to triathlon from a mid-life running background. He was not in competitive sports prior to his mid-30s when he decided enough was enough with the fat pants. After 10 years of running distances up to marathons he decided to take up triathlons by signing up for an Ironman. The looming question was how to accomplish this new goal. Trent had to learn how to swim beyond standard childhood swim lessons, ride a bike farther and faster than for a beer at the beach and then run a marathon while feeling like he had several beers at the beach. He has been an E3TRI athlete since that first season. Trent believes in the journey and the community of triathlons. He has competed in and successfully finished Olympic, 70.3 and 140.6 triathlons. Trent approaches triathlons as part of his life not something to set life aside for. He believes that goals can be obtained through knowledge, training and perseverance. If you want the goal of completing a triathlon to be a part of your life, Trent can help guide you to your goal.

CARISSA CHAMBERS GARLAND
Johnson City, TN
Carissa has always believed in the importance of an active lifestyle and making health a priority. From soccer, track & field, and cross-country in middle and high school, to intramural sports all throughout college, she has always loved to challenge herself to reach new goals. After finishing optometry school in 2015, she began her triathlon journey by training for a local sprint and was hooked. She loved how triathlon could be a lifelong sport with the variety of workouts, cross training, and incredible people she met along the way.
Since then, she has finished triathlons up to the full IRONMAN 140.6 distance, while also pursuing her passion for trail ultrarunning in the off season. Her focus in coaching is to allow training and racing to fit into an athlete’s already busy lifestyle. She understands that everyone comes from a unique background, and she enjoys working towards each person’s individualized goals.
In addition to coaching, Carissa is a partner in an optometric private practice, which gives her a realistic understanding of the challenges that athletes face in achieving a work, life, family, & training balance. If you’re ready to embark on this rewarding journey, Carissa is ready to customize a plan to help you reach your goals.
