This is the plan for a intermediate Triathlete that wants to finish a Half easily and feel strong at the end. You know you can finish a half no worries, but you want to push it a bit and see where the edge of the envelope might be. This plan will require you to use at least 10 hours a week in order to get in the three sports. I have written this so you don't need a power meter, but it will be helpful if you did. You will need a heart rate monitor though. These are the same workouts that I have given my triathletes and I know if you stick with the plan, you'll go great!
