This beginner Half Ironman training program is designed to have you ready for a 70.3 Half Ironman in 12 weeks. During this program you will have three to four exposures in each sport each week. The program runs on a four week cycle (three weeks building/training load, one week recovery/adaptation). The program is progressive meaning each week builds in volume as your fitness improves. Consistency is crucial for success so do your best to really commit to the entire program. Intensity recommendations are for entry level triathletes looking to complete a 70.3. It is very important that you establish what that intensity is for you either through a Functional Threshold Power (FTP) test or a similar test.

Nutrition Tips

Nutrition is incredibly important during longer events. Everyone is different but there are some simple guidelines you can follow. My recommendation is to start with these numbers and troubleshoot from there. You may find this is too much or too little so adjust accordingly. All of your longer weekend “race simulation” workouts should include nutrition practice as well.

Aim for the following:

  • 500-1000 ml of fluid per hour 
  • 50-75 g carbohydrate per hour
  • 500-1000 mg sodium per hour
