What a fun contest, Cajun and Buffy! Thanks!
Okay:
Classic: Sun King, because I had a brief flirtation years ago with a very handsome young man named... Sun King. No kidding. I saw his driver's license. His parents were hippies.
Mile: Free Thinking, because I like to think I am.
Distaff: Lemons Forever, in honor of the only two cars I ever owned. Suited them both.
F/M Turf: Toss up between Film Maker and Ouija Board. I'll pick Film Maker, because of the short film my husband and I just shot. It stars sock puppets.
Juvenile colts: Pegasus Wind. I was a big Greek mythology nerd when I was a kid. Enough so that when I went to see "Clash of the Titans" I complained to my parents that Perseus didn't tame Pegasus; the movie was all wrong!!!
Juvenile Fillies: She's Included. As a kid I was a geek and always felt on the outside, looking in.

I'm still a geek, but a more socially adept one.
Sprint: Commentator. Because I have an opinion about everything and I usually verbalize it.
Turf: Scorpion. I love the creepy crawlies.
I think I'm going to send this to my husband and ask him to pick names, too. It's his usual handicapping strategy, anyway.
Hey, C and B, can we repick if our choices don't make it into the race?
