First day of 5K training

Today is the first day of my 5K training cycle... in an attempt to break my 5K PR. Yahoo! This is the training I will follow: http://www.halhigdon.com/training/50935/5K-Advanced-Training-Program Unfortunately for me... I had a fast 5K for me when I was running a lot... even though I wasn't really training to run 5Ks back then. It will be interesting to see if I can get my speed up. Interesting indeed.
