David Henkel - Head Coach & Founder
USAT Level 1 Certified Coach

Growing up along the coast of NJ, Head Coach David Henkel, was a fixture in the water: swiming, surfing and lifeguarding. He swam in college, and once he became land-locked in PA, he took to the bike to conquer the hills. He quickly became a Category III cyclist but always had the triathlon bug. Under a local coach, he developed into an elite road triathlete, earning podiums and qualifying for world championships at multiple distances. Dave also has a passion for mountain biking, and qualified for XTERRA World Championships in his first year of off-road racing.


For a decade, Dave has loved mentoring and coaching his own athletes, and greatly enjoys watching their personal growth and celebrating their successes. Dave's athletes have qualified for: Pro Card; Ironman World Championships (Kona); Ironman 70.3 World Championships; Xterra World Championships; all ITU distances on and off road (Team USA). 


Dave resides in Fairfax, VA with his triathlete wife and two sons.  He coaches athletes across the United States in a highly personalized fashion.

Katie Silfies - IRONMAN Certified Coach

Katie's life-long passion for running began at a young age after her first race with her Dad. She went on to run cross country and track in high school and college. Katie caught the triathlon bug in 2009: Finding success in local races, Katie decided to aim for bigger goals. Indeed, after competing well in Escape from Alcatraz, she set her sights on Kona. In 2012, Katie enlisted Coach Dave to take her racing to the next level. She went from placing in her age group to winning overall. Ultimately that year she qualified not only for the Ironman World Championship, but also for the ITU Sprint World Championships, earning a spot on Team USA. 


Katie believes in training smart; that everything you will do as athlete/coach will have a purpose. She believes “we are never done growing, and we always have more to learn. Small accomplishments should be celebrated just as much as big accomplishments." It is her goal to help you reach your full potential as an athlete.

Kim Wikel - USAT Level 1 Certified Coach

Kim got her start in multi-sport racing in 2009, when her sister begged her to join her in this thing called triathlon! After placing 1st AG in her inaugural race (riding a $50 mountain bike!!), she was captivated. Always looking to challenge herself, Kim increased training through the years to work up from sprint to the 140.6 distance. Now, after 30 years of soccer and high school track, she has found her love in triathlon and road-racing.


Kim’s philosophy of sport focuses on “Believe in Better.” She encourages athletes to focus inward and work at bettering their own individual performance, drive, and attitude, rather than comparing to others. She considers the small building blocks of training just as important and worth celebrating as the significant competitions. Kim has the skills and understanding to work with new athletes, and because she trains to win, she has the experience and drive to train elite athletes, as well.


Kim resides in Ohio with her husband- also a triathlete and runner, and puppy Carli, who enjoys training and cheering Kim on at races! She spends her days as a teacher and coach to high school students- including teaching classes such as Food and Fitness and Healthy Foods.

Amanda Bayer - IRONMAN & USAT Level 1 Certified

A swimmer, runner, and former Division I volleyball player, Amanda has always been active in sports and competition -- including competing in her first IronKids triathlon at age 6!  After her collegiate volleyball career to a close, she went back to her roots of swimming and running to stay active. It didn't take too long for her to jump back into triathlon. From the finish line of that first local, sprint tri she was hooked! 

While a lifetime of being an athlete helped her be naturally competitive in the age group ranks, structured training helped take her to the next level.  And she began to find the overall podium at local road races.  Then, after discovering off-road triathlon and a successful debut season, which saw her qualify for World Championships, she earned her professional racing license in 2019 and placed 4th overall in her first professional race.  

Amanda has 10+ years experience in all distance triathlons - sprint to Ironman, and with both on-road and off-road racing including: triathlon, cross triathlon (Xterra), cyclocross, and mountain biking. USAT - Elite Off Road License earned 2019.  She approaches coaching and mentoring with the same passion, discipline, and joy that she brings to her own racing.

Andrea (Dre) Pucke - USAT Level 1 Certified Coach

Born under the sign of Pisces, it seems as if Andrea was born with a love of the water, or more accurately, of being in the water. She began swimming at age four and never looked back. Growing up in the panhandle of Florida, and later living with her family near the coast of New Jersey, she lived up to her horoscope and spent more time in the water than on the sand. 

Andrea swam competitively on school teams from elementary school through her senior year of college, while concurrently competing for various clubs. In 2010 competed in her first triathlon, placing third in her age group. From there, she was hooked and sought her next challenges.

For those triathletes who do not have a swimming background, Andrea is empathetic that the swim portion can be the most challenging. Confidence, determination, and concentrating on the technical aspects of the swim during training, while minimizing poor efficiency, can help aspiring triathletes become improved swimmers.

Andrea is never satisfied with just being good enough—she believes you always must improve and be the best you can be. She exhibits this belief through her enthusiasm for the sport, and she’s not easily deterred from her goals, much like the slogan of her former Jersey Storm swim team: “Can’t Calm the Storm!”
