There are nine to eleven workouts per week, consisting of 3 swims, 3 cycles, 3 or 4 runs and a strength workout. There's a day off each week and every fourth week has a lower training volume to help your body adapt and recover. To be successful with this plan, you should have raced half Ironmans and preferably a full Ironman before.



Phil Mosley: "I have 20 years experience of helping age group athletes surpass their goals, while still making sure they have quality time available for family, friends and career. My training plans are intelligently designed around a typical work week. I set proven, time-efficient higher intensity workouts in mid-week, with longer aerobic workouts at the weekends."
