Gregory Gallagher   SpeedTheory LLC.

SpeedTheory Coaching focuses on triathlon and endurance sports. We coach all distances of triathlon with a focus on the half and full Ironman distances. We offer individualized one on one coaching in all three disciplines and build a plan specific for each athlete. We offer swim stroke analysis through underwater video. We work closely with a Physical Therapist to offer local athletes function and mobility screening along with run gait analysis.


I have 28 years of experience in endurance sports including running, cycling, and triathlon. I started out as a runner and shortly took to the sport of triathlon. I have raced every distance, from a 5k to 25k and from sprint to the full Ironman distance.
I am a 5 x Ironman, 20+ x Ironman 70.3, 2 x Ironman 70.3 World Championship finisher, 1 x ITU Long Course World Championship finisher, 1 x ITU Aquathlon World Championship finisher. I've raced for the United States on Team USA two different times in two different events.
I am USAT certified level 1 coach and a TrainigPeaks level 2 coach. Over the past six years I have coached beginner triathletes from their first race, to world championship qualifiers. As a coach, I use data such as heart rate and power to help my athletes meet their potentials in training and racing alike.
