So Excited.....

Some background on me..... 44 years old and in the worst shape of my life.... and I got the idea to compete in a triathlon for my 45th birthday.  I am the mother of 10 and the grandmother of 4. So, I talked to my oldest children and told them what I wanted to do and asked for them to do it with me.... had two takers.... my oldest son and second son. 
So, the practice was to begin.... and then I got pertussis....
started training a month late.
When I began, my resting heart rate was 109 and I would run for one minute at a time and feel like I was dying. 
I have been so discouraged..... have had constant set backs.....
My bike is old and I keep having problems with it, lost my job due to poor economy, travel has prevented training, etc.  My poor son is doing awesome in his training but had his bike stolen the other day and yet we are still trying.  I have spent time in tears asking myself what made me think I could do this in this short of time. 
Well, today I decided that time is getting short and I needed to do a bike/run brick the distance.  I have never run more than 2 miles and that was half walking.
Today I rode 12.24 miles and then started to run, right away I was having problems and walking off and on until about half a mile and then it happened.... my heart rate dropped and I just started running..... I was slow but I ran without stopping and it felt amazing.  For those of you that run long distances.... I know my little 3.39 miles is nothing but for me.... it was the best feeling ever!
