I know you already ran, but I guess my response would be that when you're sore from something like running, especially a program you've recently started I'd encourage you to NOT run when you're already sore. The tendency to get injured while your muscles are sore and "vulnerable" is great. Because the muscles hurt you will tend to favor a running form that decreases the pain and protects the muscles. This could equal a running with a gait that is very very wrong and will increase the likelihood of injury. When you're sore from a run or weights do some cross training instead, like swimming, the eliptical, etc. until you regain your running legs.
