IRONMAN Boulder, Base/winter training, 140.6, 12 weeks by Eric Kenney, Ek Endurance Coaching

This plan is designed to maximize time in the fall and winter months when training out side can be tough. We have even seen gains in threshold power on the bike and speed in the water and greater efficiency on the run. This is due to the flexible but detailed "focus" periodization we use. You will see up to 10 hours of training per week depending on the phase. This plan comes with doc's on managing your plan, descriptions of zones, core strength routines and more. contact Eric at for customized plans or consultations
