BSX Athletics: Beginner 70.3 - 4 to 10 Hours per Week

This 18-week plan was designed for athletes who can already comfortably swim for 30 minutes, run for 45 minutes, and cycle for 1 hour prior to beginning Week 1. It has been periodized into a General and Specific phase, with the General phase comprising the first 9 weeks. It also includes five lactate threshold tests: cycling tests in Weeks 3, 9, and 15 and running tests in Weeks 6 and 12. These tests are opportunities to use BSX Insight to measure your progress and adjust your training zones. Be sure to complete a lactate threshold test before you start the plan in order to establish your initial zones. The swim schedule has a great deal of flexibility and swim workouts can be moved at your convenience. Like all BSX Insight/Matt Fitzgerald Training Plans, the Beginner 70.3 Plan is based on the 80/20 Rule, which stipulates that 80 percent of total training time is spent at low intensity and the remaining 20 percent at moderate and high intensities. This approach is scientifically proven to produce better results for triathletes of all levels. See for yourself!
