"Let me express my thanks for guiding me through one of your plans for my first Ironman 70.3 last weekend in Luxembourg. I did 05:44:11 with a big smile on my face at the finish line and ZERO pain in my muscles!!!" Giordano Mastrocinque, June 2016

You can start this plan any Monday. Generally there are 7 workouts per week, consisting of 2 swims, 2 cycles, 2 to 3 runs and a strength workout. Weekends generally involve a long ride and a long run, with shorter workouts in the week. Every fourth week is an active recovery period with a lower training volume to help your body adapt. To be successful with this plan you would ideally have around six months of triathlon experience.

Sample Day 6
Aerobic Endurance Ride

These workouts will build your endurance so that you can do a half Ironman ride with energy to spare for a good run.

Ride mostly in Zone 2 today, at a steady, conversational pace. You can go into Zone 3 up any hills.

Sample Day 7
Aerobic Endurance Run

Most Sundays we will gradually increase your run-endurance, to a point where you can run 2 hours in training without feeling excessively tired afterwards.

Keep the intensity in Zone 2 at all times. Do this on soft ground/trails if possible.

Phil Mosley
My Pro Coach

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. As an athlete and a parent I know how challenging this can be.

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.
