This 20-week Ironman Training Plan is intended for an athlete with a few years of experience in the sport of triathlon who is looking to have a strong performance on race day. It is appropriate for an athlete tackling this distance for a first time - provided that athlete has been invested in the sport. There is one rest day per week built into the plan, and weekly hours ranging from 7 - 19. The long runs are generally on Saturday and long bikes on Sunday, so that RTB athletes can take advantage of the RTB Sunday ride. However, the athlete may choose to switch the long run/ride days. The workout descriptions are based upon RPE - or "Rate of Perceived Exertion". Athletes unfamiliar with RPE and more familiar working with Heart Rate or Power Zones can reference a chart included in the "Plan Details".
