I've been building my base for the last few months doing each swim, bike, run 3x/week. The bike/run I have been using a heart rate monitor to judge intensitiy keeping it around 65-75% for the duration of the workout biking (normal length = about 1 hour and long day 1.5 hours and cadence about 90rpm; running normal about 45 minutes; long 75 minutes with cadence of 83 rpm and have been increasing time about 5% a week). Swimming I have just been swimming a warm up set, a long set (increasing about 5-10% per week currently at 60 laps (25 yard pool) and a cool down set.
I'm doing Ironman Wisconsin and the 36 weeks starts the first week of January. So I started looking through the workouts and they have very specific directions such as run at this intensity for this distance then easy for 1 minute then this intensity then blah blah blah. Swim it has me doing specific pull/kick drills, etc. Biking it has me doing all kinds of different gear/variable workouts. Are all these details really necessary or can I just put the time in running, biking and swimming that they recommend. In addition I'm taking triathalon specific swimming lessons for 30 minutes once a week and have completed 2 of 6 of my total immersion private lessons. For people that have followed this program or another program what do you recommend? Thanks a lot.
