About us

Our ethos

Be healthy. Feel good. Compete. Enjoy triathlon long term.

Triathlon is an incredible sport, offering more variety and benefits than swimming, cycling, or running alone. However, combining three sports can increase the risk of overtraining, which can affect health, mood, energy, and body composition.

By finding the right balance of aerobic work, strength training, and lifestyle management, it’s possible to excel in triathlon while staying healthy, motivated, and consistent. Moderate, consistent training far outperforms sporadic periods of high-volume or high-intensity effort, keeping you injury-free and enjoying the sport for years to come.

“David laid out every session I did for 7 days per week, sometime for multiple sessions per day. We corresponded regularly and had phone calls whenever I needed. He laid out race strategy and was a constant support. Extremely good value for money.”
