goals for time trial

I've been kind of unsure how well I will to today. I'm not sure how fast I'll be able to do, since it's early in the season, although I feel like I'm in relatively good shape and I feel faster than last year. So my goal is to run around 19:20, which would be a pr. I should go out in about 6:05- 6:10 for the first mile. That's my goal. I hope that I can find a good rhythm for the rest of the race, to keep the initial pace.
