Santa Clarita 21Km Race

I am Preparing for my next challenge : the Santa Clarita Half Marathon on Nov 5th .
21 km or 13.1 miles.
It will be my second time at this distance and represents an enormous athletic challenge.
Two years ago I was unable to run 1 mile. Last fall I started lenghtening my runs until I
got up to 6 miles. After a successful race at Venice Beach . I focused on the the 21 km distance.
I completed my first Half marathon in Agoura Hills on march 4th . It was the hardest and most demanding sporting challenge I have ever undertaken.
Since I have been training with the local running club and also from the Gym at work. The variety of routes , lenghts of runs and pace and company has kept the training interesting.
I am shooting for a time of 2 hours and 10 minutes .
