3 weeks out. Test failed

Today was a faster workout. Basically a test to see where my speed is. Test failed. F. I got out early am and felt ok during the warmup. 30+ minutes several decent strides and away I went. I have done all three sub 4:40 before. Today was not to be. 4:52. I felt somehow tight. Like I could go much faster but just couldn't. ??? Does that make sense. After 5 minutes of jogging I decided to attempt Number 2. 4:54. The hard way. Just no snap in the legs. I decided to call off the last one and make it a little longer day. I am definitely feeling down about it. Leading up to the race I was hoping for three fast ones. I know I am very fit but need to keep the positive momentum going. Thursday is a big one. Actually the biggest of this buildup. I may not post until after that. We will see how I am mentally.
