They’re at the post… in two months. Until then, here are 10 things to keep in mind for betting the Kentucky Derby.

1. Churchill Downs is a dirt track. Look for horses that are good on dirt or across many surfaces.
2. It’s 1-1/4 miles, a long haul for unproven sprinters.
3. Of 32 odds-on favorites, 17 won the Derby and 11 finished second.
4. Only three fillies have won; the last was Winning Colors in 1988.
5. Winning Colors was also the only registered roan to win (she was actually gray).
6. Kentucky-bred horses have won 100 of 133 races.
7. Post positions No. 1 and No. 5 have each produced 12 champions.
8. Seven geldings have won, but only Funny Cide (2003) since 1920.
9. No winner since Iron Liege (1957) finished worse than fourth in his last Derby prep.
10. D. Wayne Lukas leads active trainers with four Derby wins – including Winning Colors.
