Greg Penner   Arete Endurance

Arete Endurance is my mission to help endurance athletes be all that they can be.

Arete ( aa r eh t EE ) is a Greek Word that means excellence. It covers athleticism but also means reaching your highest potential of mind, body, and soul.To be all that you can be with what you’ve been given.


I have been involved in endurance sport for most of my life as a competitor, race director, and coach. What started as a boy racing the school bus home grew into a young man chasing mountain bike cross country racing across North America. From there that turned into Marathon running and Triathlon. Driven to see how far I could go in each sport has given me the opportunity to compete in some of the most prestige’s events in the World. Highlights Include:

Cross Country Mountain Biking: Achieved World Cup Status as a Pro/Elite
Running: Several podiums at MB Marathon (1:13 1/2 Marathon PB, 2:36 Marathon PB), Run in Boston, NYC, and Chicago Marathons
Triathlon: Ironman Hawaii World Championship, 70.3 Ironman World Championship
Ultras: 597KM in 24 Hours on Bike, Frosty Mountain 50

I coach because I love to use my experiences and passion to help you reach your goals. I know what it is like to juggle family, work, and a busy schedule but yet still reach for your very best in sport. I coach because I know the transformation that happens when someone aims to give their very best and believe I can help with that pursuit. The word Arete perfectly describes my belief, that true success is achieved by working on body, mind, and spirit. Whatever your goals are I create realistic, challenging, and flexible training plans based on a life time of experience and knowledge.

I’m still very involved as an athlete and believe a coach should lead by example and experience.
