5K Time Trial

I did my first 5K TT of the season today: 19:54 (~6:25/mile).  It has been exceptionally cold so far this year, but today was one of those fluke days in January when it gets above 50.  It was in the low 50s, rainy and windy, but I ran in shorts and a sweater. By the end, my shoes and compression socks were totally soaked. I felt horrible, but that's how you're suppose to feel when you go hard, right?
     Had a weird HR response: first mile felt pretty easy, but starting at the hill at the beginning of the 2nd mile it got a lot tougher. Likely those big jumps in HR represent limitations in the wrist-worn HR monitor (i.e. lack of sensitivity to subtle changes in HR).
