Scared runner = FAST PACE!

So I headed out for a run tonight and decided to cheat (I didn't want to run all the way up the Ford Hill so I cut through their parking lot and headed down the back side). This is not a normal route for me and as I was heading down the road I kept thinking I was hearing noises (I was wearing my headphones so I wasn't quite sure what they were). I got a little freaked out so pulled one head phone out of my ear and kept running (or maybe I should say RUNNING. I wanted to get off that street and back to the main road). I didn't get very far before my breathing was out of control and my insides got hot. At first I thought it was just because I was scared but a quick glance at my watch explained it all. I was running a 6:58! Needless to say, that didn't last long but I'm thinking that being scared on my night leg might on the relay might just bump up my pace a little bit!
