Eric Gauthier   EG Multi-Sport Coaching

I am a full-time triathlon coach and train recreational to elite-level athletes. All triathlon distances, criteriums, Time Trials, and running distances.

I coach athletes locally as well as worldwide, with athletes currently in Europe and Asia.

My coaching approach is totally personalized and organized around your personal and professional constraints.

I also organize biking trips to France, including riding the major Tour de France climbs, and discovering the Provence region.


I am a USAT level 1 coach, an International Triathlon Coaching Association - ITCA coach, and USAC level 3 coach.

I have been doing triathlon since 1988, all distances from Sprint to Ironman.

I have been coaching triathletes, cyclists and runners since 2007, from beginners to age group winners, and athletes qualifying for national and world championships.

I apply scientifically driven and proven approaches, where science can be combined with pragmatic experience to develop customized, optimum training plans while taking into consideration individual capabilities, family constrains and work schedules. Nutrition and strength training are included as well. I have a 100% success rate at training athletes compete at the Ironman distance and had athletes complete their first 5K marathon race, first sprint triathlon, or winning their age group.

In 2014, I won the US national aquabike championship at the 1/2 Ironman distance.

As a cyclist, I am a time-trial specialist. I have also ridden all the major hors category climbs in the French Alps and Pyrenees, including Aubisque, Tourmalet, Peyresourde, Luz Ardiden, Glandon, Croix de Fer, Telegraphe, Galibier, Mont Ventoux, as well as the infamous Alp d'Huez climb. Once in a while, I also enjoy racing criteriums.

I also do mountaineering.
