Join Coach Troy and athletes from the Life Time Fitness Cycle Club in a workout designed to improve oxygen transport to hard working muscles, building your endurance and aerobic foundation. Filmed in Leadville, Colorado at 10,000 ft., this workout features several athletes who compete in the Leadville Race Series, including the Iconic Leadville Trail 100 Mountain Bike race. An aero base building session, athletes train in Zones 2 and 3, targeting their aerobic and fat burning engine. Larger "aerobic engines" translate to greater stamina and power output on race day, so focus on this energy system is imperative for the competitive cyclist and triathlete. So hop on the bike and get ready to "Build your Base" with Coach Troy!
