For this 12 week plan you need: A pace clock at the pool (a watch or tempo trainer would work); A 400m open water course; A heart rate monitor for cycling; A gps watch for running.
This is a standard plan for beginner athletes who want to complete a 70.3. The duration of training ranges from 2.5 to 9.45 hours per week. There are a maximum of 3 sessions for any one discipline each week. Mainly there are 2 swims, 2 bikes and 2 runs each week. This plan includes strength sessions that can be done at home.
