WORLD-CLASS COACHING FOR ENDURANCE ATHLETES OF ALL ABILITIES

  • IS YOUR TRAINING JUST A WASTE OF TIME?

    Many athletes are training at the wrong intensity and limiting the progress they could make. This can lead to burn out, injury and sub-par race results. Having a heart-rate monitor is not enough! You need to know how to use it for YOUR needs.

    A Blood Lactate Test with Coach Gareth will give you the exact insights that you need to get you training like a pro’ with science and accuracy. Know your true training zones, how to use them and what workouts YOU should do to hit your potential.

  • IS YOUR PROGRAM 100% CUSTOM FOR YOU?

    In this modern world of A.I. programs and free downloads, many athletes are struggling to hit their athletic goals. This cookie cutter approach is not what you need. Doing someone else’s training with little to no human input will leave you frustrated and slower than you should be.

    Custom coaching with Coach Gareth will give you a program that is built for you, but more importantly, that adapts to your life as things come up. Regular data analysis will ensure that you are training accurately and you will have a coach who is always looking out for you to keep you on track and motivated.

  • DOES YOUR NUTRITION ACTUALLY WORK?

    Coach Gareth has helped the best of the best to conquer their nutrition, hit their ideal weight and nail their fueling. The result? Multiple world championship wins and sustainable health and performance for years to come. He can strip away all that is not working for you and replace it with a simple solution to help you thrive.

  • “When I first met Coach Gareth I immediately knew his attention to detail & scientific approach was a winning choice. Now 16 years later with a growing family and limited training time the precision of Gareth’s training plans allow me to not waste anytime and still chase my dreams.”

    JAMEY YANIK // Top 5 Leadville 100

  • “Coach Gareth and I have been working for more than 2 years. Thanks to his detailed analysis and personalized coaching plans, I was able to shave off over 40 minutes from my marathon time. I would recommend him for any serious amateur wanting to see what their maximum potential is”.

    ALI ARSAN // Sub 2.50 marathon

  • "Gareth has been my coach for the past 13 years, initially for my first Ironman and for a number of 100 mile ultramarathons since then. He uses cutting edge science to dial in training zones, writes excellent plans, and is superb at helping me to psychologically prepare for the rigors of race day".

    LAWRENCE MILLER // Multisport Athlete

  • “I started working with Gareth over a decade ago and then took a break for a few years to "retire" and only run. When I re-entered multisport racing in 2021, I reached out to Gareth to help set up a program and help me hit my goals. My fitness keeps going up and my times keep going down - when you get to hit a new half marathon PR 15 years after your last one - you know your coach is doing something right. His testing and programs have me training smarter and more efficiently than I could do on my own”.

    ERIKA CHAU // Team USA Multisport Athlete

  • “I have been working with Coach Gareth for several years now. His lactate testing is fundamental to my training as a healthy adult. As a doctor, I often recommend my patients to the Coach for lactate levels too. I’ve enjoyed training with him on and off over the years. I improved my health, strength, aerobic capacity, and enjoyment of running under his coaching. Gareth is also a very generous and funny individual. Overall, a gem”!

    DAVID EISENMAN M.D. // Weekend Warrior

  • “As someone whose running pace is only slightly slower than some people’s brisk walk, I had a bit of hesitation about reaching out to Gareth, given the caliber of athletes he works with… I had so much fun working with him! We did a gait analysis, along with the lactate threshold and sweat testing. I learned SO much - Gareth broke it all down in a way that was very easy to understand, and with a few quick drills, also gave me an “Oh! So THIS is what it should feel like” moment”

    SUSAN SULLIVAN // Weekend Warrior

  • “Coach G has been training me for many years. I started with Marathon and added Triathlon a few years ago. Gareth develops training plans that are both challenging and engaging, using periodization and heart rate metrics to maximize training value resulting in peak performance on race day. While working with him I’ve gone sub 2.50 and won my age group at the Tokyo Marathon and qualified for the kona World IRONMAN championships”.

    BRIAN TEMPLE // Champion Runner & IRONMAN
