Second thing I look at is the balance. Is it run heavy, swim heavy or bike heavy? Is it a balanced plan? Personally with me, I feel good about the swim, decent about the bike and hate the run. As you know that is normally where I lose the most time, so I want to make sure I am using a plan that focus on my
Third thing I want to see is how is the plan laid out? Is it even possible for me to hit the designed workouts with my family schedule and my work schedule? Is their some flexibility in it? Are there scheduled rest days? Nothing is more frustrating than to get a plan together and then find out there is now way to execute it. So I want to make sure it is a plan I can actually follow.
Lastly, I want to look at the detail of the plan. Is Monday a swim 40 minutes, bike 60 minutes day? Or is is broken down for me. Does that 40 minuite swim come with a workout designed and explained to me? that is what I like. I admit, I get bored going to the pool knowing I have to swim 40 laps. I would much rather have it broekn down for me with a warmup, main set and cooldown (plus I honestly believe that is how you get faster, not by simply swimming a bunch of laps)
Normally I would just get a plan off of beginnertraithlete.com, but the ones they had for HIM did not really work for me, so I searched elsewhere and found a plan that I think will work. It comes from a site called trinewbies.com. Now the fact that the website is called trinewbies does not bother me at all (well a little, but I am getting over it) It is an 18 week plan, is the right balance of S/B/R. I actually like the way it is laid out (which means I don't always have to stay up late to get workouts done like I did for IM) and it has detailed plans for the S/B/R.
The only other issue I have is that sometimes I will think I decided on a plan until I run across another plan, and then I see another plan. So I am taking a few days to really dive into this plan and make sure this is what I want and that it will work for me.
So how do you decide what training plans you use? Did I miss anything on the decision factor?
