This is a Half Ironman Distance/ IM 70.3 specific training plan designed for entry-level or novice athletes. It ranges from 10 to 15hr per week, with the weekly average for the entire plan being approximately 12hr.
Well-proven session scheduling, programming and training progression principles form the basis of this plan but appropriate for someone starting their half distance training journey, in terms of session durations and intensities.
Prior to starting this plan, we would recommend being able to complete 10-20 minutes of non-stop swimming, 1 hour of cycling and 40 minutes of running at a very comfortable, aerobic pace as the base requirements to commence Week 1 most effectively.
Good luck!
