First Time 70.3 questions

I was scared to death when I was training for my first 70.3.  I had completed two (2) marathons and had bonked on both of them.  I didn't know how I would make it through a 6-hour triathlon if I couldn't even get through a 4-hour marathon.  I was a good runner and had been winning my age group at 1/2 Marathons races for six years leading up to the 70.3 but hadn't done any competitive swimming or cycling and was starting from zero on both of them.  I enjoyed the training though.  I got to take weekend bike rides through beautiful scenery and got to speed down hills which was an exhilarating feeling.  Swimming every day on my lunch break I made new friends and it was a wonderful way to break up the workday.  I trained for 6 months for my 70.3 and found BT about 2-1/2 months into my training.  I joined one of the BT mentor groups and learned from the questions of other people in the group and when I got brave enough started to ask my own questions.  I didn't think that I would be totally ready to race in 6 months of training but I wanted to have the experience and just focused on what I could do to be as ready as I could be with my limited time to train.
