St. Patty's Day 5k

I decided to drop the Pumped for Pets race on KI for the St. Patty's day 5k out in Denton. It's only 26 days out and I would love to PR at that race. Problem is, I haven't been working on increasing speed, only increasing distance. I'm going to try and incorporate some speed work into my training for the next few weeks. My goal is to break under 27 minutes. To be honest I'm shooting in the dark here but going into an event without a goal seems pointless.

I need to come up with some sort of outfit though. Thinking I'll just rock some knee high clover socks. What is everyone else wearing for their St. Patty's Day Races?
