Phasic training for a triathlon. A well thought out plan has you start with your base. Whatever that base may be. Don’t fall into the trap of I have to get in shape to start training. You will get in shape as you train. a 12- week plan is more than adequate for your first event. There should be build weeks and taper weeks plugged into your plan. Typically 3-weeks you build and 1 week you taper and you continue this pattern through training. So weeks 1-4 are base building. 5-8 are intensity phase where you slowly add distance and intensity. weeks 9-11 peak phase where you put it all together and week 12 is taper. Follow our training plan and you will cross that finish line.
