David Henkel - Head Coach & Founder
USAT Certified Coach Logo

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 Vienna, 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
IRONMAN Certified Coach logo
Josh on the way to the podium at Richmond

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
USAT Certified Coach Logo

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.

Andrea (Dre) Pucke - USAT Level 1 Certified Coach
USAT Certified Coach Logo

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!”

Amanda Denney - USAT Level 1 Certified Coach

Amanda's racing journey began with little to no experience or knowledge of the sport. Over the years, with some blood, a lot of sweat, and a few tears, she began wining age groups and placing top ten in many Ironman races. Training and participating in triathlons developed into one of her true passions. As a coach, she harnesses that passion and shares her love of the sport with others by helping them to reach their racing goals. Indeed, she not only helps athletes cross the finish line at events they didn't think possible, she's helped them achieve world championship qualification as well!

Amanda has been working as an Athletic Trainer at Wilmington University for over 10 years years. She helps athletes with injury prevention and rehabilitation while focusing on a healthy return to activity to ensure longevity in their college sports careers. To keep sharp and satiate her need to help those that would like to focus on physical fitness, she is also a certified personal trainer and has a client base that encompasses a wide variety of physical fitness levels.


Amanda's mantra for success is believe in yourself, never give up, trust the process, and ALWAYS train and race healthy!

Leslie Neff - IRONMAN Certified Coach
IRONMAN Certified Coach logo

Leslie grew up playing competitive sports in high school and was a Cycling Instructor and HIIT Group Exercise coach at her local YMCA when she was asked by a friend to sign up for her first triathlon. She never looked back.


Despite not having a background in swimming when she entered her first multi-sport racing event in 2010, Leslie worked extremely hard over the years to become a competitive triathlete - she quickly went from completing two sprints and an Olympic distance in her first year of competition into a 70.3 and 140.6 in her second and third years respectively. 


Leslie’s approach to training is simple. “Be fiercely competitive and fiercely humble.” This mantra extends to her coaching.  She also believes that participation in triathlon is a lifestyle that will involve big goals and challenges, but at the end of day there is enjoyment and balance.  Leslie is very motivated to build resilient and tenacious athletes and help them achieve their personal goals while keeping balance in their lives. 


Leslie lives in Pennsylvania with her husband and dog, Moosh, who enjoys running with her.  Leslie also works full time as a counselor for Veterans at a local VA Hospital.

Vince Lafashia - IRONMAN Certified Coach
IRONMAN Certified Coach logo

As the youngest of 4 kids growing up in Delaware, Vince learned to ride a bike to keep up with the older kids and has never stopped riding! Cycling is not just a passion for Vince, it’s a lifestyle that now includes roads, gravel, trails, and even beach cruisers. From riding, his athletic background expanded to include strength training, running, and swimming. Despite being a self-taught swimmer, Vince’s persistence resulted in efficiency gains in his mechanics and he now comes out of the water with the lead age-group swimmers in a triathlon. 


Vince’s coaching attitude encompasses balance, patience, and adaptability. He recognizes athletes juggle many competing priorities and responsibilities and strives to understand his clients as individuals, not just athletes. Vince is a true student of the sport: He continually researches the latest equipment, strength and mobility exercises, and nutrition offered to triathletes. Vince educates himself (and his athletes) by reading reviews, watching videos, and listening to podcasts to understand how to continually elevate his coaching and his athletes’ performances.


Vince and his wife are both Speed Sherpa athletes and have been a part of Speed Sherpa family from the beginning. They lead virtual spin sessions via ZWIFT weekly for Speed Sherpa and their local triathlon team, and love supporting novice to highly experienced triathletes. They live in Delaware with their three dogs and escape to Cape May, NJ every chance they get.
