I started running 3 and a half years ago.  My husband was always eliciting me to make exercise, but I had a lot of excuses: my son, my work, my home, etc.  The true was that I had never found a sport that makes me feel good with myself and see the progress fast.  I remember the day he came home with a bag full of running leggings so I could start running with no more excuses.  I decided to start and once I did it I could not stop.  Here I am.  I started running 1 km, then 3km, next I ran 5km.  From there, I jumped to run 10km, this was the last day of year 2011.  Then, I continued training and started to run short races in US.  Again, on December 2012, one of my running friends told me about running the half marathon, I had been running for 2 years, so I have de condition.  I started to train for two months (December and January), and on February the 8th, I ran my first one!!! 13.1 miles or 21km.  It was a great experience and I will never forget it.  I continue running short races, but on November I will run again the "half".
