This marathon training plan is a good fit for beginners and other runners who need or prefer a low-volume program. The plan is 18 weeks long and features four runs per week. It also includes five lactate threshold tests, in Weeks 3, 6, 9, 12 and 15. 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. You should also be able to run comfortably for at least 4 miles before you start.
Like all BSX Insight/Matt Fitzgerald Training Plans, the Beginner Marathon 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 runners of all levels. See for yourself!
