This Half-Dsitance Triathlon Training Plan is intended to help you prepare over the last 12 weeks leading up to your event. The workouts are suitable for beginner and intermediate triathletes who are currently training 4-6 hours a week or more in a mix of swimming, cycling and running. If you do not already have a consistent training routine established, you may want to consider first starting with one of our 8-week Sprint or Olympic distance Triathlon training plans before beginning this half-distance plan.
