Good Luck Seth, congratulations on challenging yourself, I know it's been a long road for you.
You're going to love it.
I was hooked after my first one. Now that I have run a couple races since my surgery, I want to run more of them to challenge myself. I have never run the Turkey Trot on Thanksgiving morning but I'm thinking this year may be my first!
Depending on how cold it will be, layer. I found for me that was running leggins, turtleneck long sleeved shirt, light weight cotton gloves, sweat band that covered my ears. You'll be cold at the start but you will warm up quickly. You can take the gloves off after you warm up and stuff in your waistband. We don't get too cold here in TX so no need to wear heavy sweatshirts. If the temp is under 40 degrees, add a lightweight sweatshirt to the turtleneck to take off when you get too warm, you can wrap it around your waist or do like most folks, if it's not a favorite, toss it.
If you have a running store in your area, call and ask them if they have local race schedules. You could check online as well, I found these
RACES if you are interested. Some of the races are family friendly too.
I'm excited for you and I look forward to your post race report. Pics are always appreciated too.
