An intermediate-level, 12-week Ironman Build-Peak-Race period, this training plan was designed by Joe Friel using the principles described in his books--The Triathletes Training Bible and Going Long. Both over- and under-50-year-old athletes may use it. Following this plan will prepare you for your Ironman race by building exceptional aerobic fitness.
To start this plan you should have completed 1 or more Iron-distance races and have a goal of improving your personal best race time. Weekly volume ranges from 16 to 19 hours with 14-hour R&R weeks every third week to allow for recovery, adaptation and improved performance.
This plan is simple to follow and is written in common triathlon language as you can see by clicking on the PREVIEW. Suggestions are made throughout to guide you in making training and race planning decisions. If you have questions you may contact a Training Bible coach at www.trainingbible.com.
