This program is a beginner plan to bridge you from an a Half Ironman to Ironman using a HRM with the confidence that you can complete the race without difficulty.
Highly trained athletes can maintain a specific HR longer than a newbie without much creeping; their endurance is greater—thus able to keep pace efficiently and without much additional increase in HR.
My doctor says 140bpm HR is my max, but that feels like a walk in the park... I don't know what to do, how to train, and my motivation is waning. Any suggestions?
The schedule consists of 3 workouts per week in each sport, 2 days of strength training and core work too. The maximum volume is around 7 hours toward the end of the 12 weeks.
