What happens to your training when "Life Happens"?

During any "Epic" journey you are bound to run into the road bump, life, lack of foresight or other problem. I have already run into two slight problems and must adjust my training program.

First, I was guessing that the event would happen on July 27th, but instead it is actually schedule for July 20th, which means I have already lost one week of my 52 weeks. And it saying one week out of a year does not sound like much but when I look at where I need to be, I think one week could make a big difference.

Second, I did not account for Christmas or the "Holidays". Now I don't know about you, but I always get really busy with shopping and spending time with family over the "Holidays". And I am sure I could give the "Ironman Training" excuse to get out of many of the Holiday Activities, but I truly enjoy them, and I am more likely to skip the training during that time, than skip out of the family thing. Being honest with myself and knowing myself well enough, I would rather schedule my training around this likely pitfall.

So here is the Updated Schedule

Periodisation #1 (21 Weeks)
--5 Weeks Prep
--4 Weeks Base 1
--4 Weeks Base 2
--5 Weeks Base 3
--3 Weeks Taper

Recovery (4 Weeks)
--4 Weeks of easy short workouts

Periodization #2 (26 Weeks)
--8 Weeks Prep
--6 Weeks Base 1
--4 Weeks Base 2
--5 Weeks Base 3
--2 Weeks Taper
--1 Ironman USA event week
