Jim discovered cycling in college while training for ski racing and quickly found his true passion on two wheels. A lifelong skier and former PSIA-certified instructor, Jim has been an avid road, mountain, and gravel cyclist ever since.

After racing across Colorado, Virginia, Washington, and Utah, Jim settled in Boise in 2003 and ran several seasons with Lost River Cycling. His professional background in healthcare engagement led him to coaching, where he’s helped athletes of all levels unlock their potential since 2006. Many still call him “Coach Jimmy.”

Josh Tostado is a professional mountain bike coach and endurance athlete with more than 20 years of racing experience. Over his career, Josh earned four U.S. National Championships and reached the podium twice at the World Championships, establishing himself as one of the most respected long-distance mountain bikers in the sport.

Josh’s coaching philosophy is built around intentional intensity: athletes should train very hard or fairly easy. He emphasizes the value of true Zone 2 aerobic development while avoiding unproductive “middle-zone” efforts that don’t drive meaningful progress. He also considers strength training a cornerstone of long-term performance, injury prevention, and race durability.

Believing that doing the same thing all the time stalls growth, Josh adapts training plans throughout the year—matching workouts to each athlete’s season, goals, and readiness. His mission is to help riders become stronger, faster, and more resilient through smart, purposeful training.
