greg reverdiau high altitude training institute


Founder, Coach & Trail Guide

Greg Reverdiau is certified VDOT O2 Distance running coach and an accomplished athlete. He has competed in a variety of event from 5Ks to Ultra-marathons, and Half and Full Ironman Triathlons.

The idea for the High-Altitude Training Institute came to him after moving from Florida to Northern Arizona. His fitness level and racing times improved considerably, even during periods of low training. What started as a means to lose weight quickly became a passion that he hopes to pass along to others.

His training philosophies include quality training sessions mixed with a balance of healthy eating and living. A sub-three hour marathoner, his current goal is to improve his marathon and half-marathon times (PR: 1:16:23). Training from Prescott, he hopes to spend more time fastpacking in nature to prepare for multi-day events in the surrounding National Parks. When he’s not running, Greg enjoys his second passion: aviation. He is a Commercial Pilot as well as a licensed Flight Instructor. He also likes good food and craft beer.
