Meticulously crafted from the principles laid out in Matt Fitzgerald's best-selling book 80/20 Running, and followup book 80/20 Triathlon, this plan will provide the athlete with the same workout structure used by the most successful triathletes in the world. Each week, cycle, and the complete 19-week plan has been specifically formulated to match the research articulated in Fitzgerald's publications and ensures the triathlete adheres to the 80/20 principle. This plan is intended for athletes with a goal to finish their Sprint event as their personal best time. It assumes that the athlete has previously completed a triathlon of any distance, or has a strong history in one of the three disciplines (swim, bike, run), and can already comfortably swim, bike, and run for an hour and cycle for 1 hour prior to beginning Week 1. Not sure which level is right for you? Each 80/20 plan comes with a Level Guarantee: if you discover that the level you have selected is too hard or too easy for you, simply contact david@dwcoaching.com for a complimentary switch to a different level within the same triathlon distance. Supporting resources and documentation for your plan, including Zone guidelines, can be found at http://mattfitzgerald.org/8020training/ Please note that in this plan the swim is prescribed by distance, and the bike and run by time, therefore the preview below will not reflect the plan's complete time and distance. As a new publication, early purchasers of this plan will be able to contact the co-author, David Warden, directly at david@dwcoaching.com, in order to request clarification on any items that may be unclear in the plan.
