When Orb steps into the starting gates of the 138th Preakness Stakes at Baltimore's Pimlico Race Course on May 18, the 3-year-old colt will try to become the 34th horse to win the first two legs of the Triple Crown.
Orb, who won the Kentucky Derby on May 4, is an early favorite for the Preakness, but the favorite wins only about half the time. He'll be running against many of the horses he beat at Churchill Downs, as well as a few well-rested thoroughbreds who skipped the Derby.
Among the competition are Mylute, ridden by Rosie Napravnik, who will be the third female jockey at the Preakness, and Goldencents, whose jockey, Kevin Krigger, wants to be the first African-American to win the race in more than a century.
Here's a quick look at the challenges ahead of Orb, and the rich history behind the race known as the "the middle jewel."
Oct. 25, 1870: The date Pimlico Race Course opened. It is the second oldest track in the country, behind Saratoga.
May 23, 1873: The date of the first Preakness.
$2,050: The size of the winning purse at the first Preakness.
$1 million: The Preakness' current purse.
1 3/16 miles: Length of the Preakness track, 1/16th of a mile shorter than the Kentucky Derby.
14: Number of positions available in the 2013 Preakness.
3: Number of horses scheduled for the 2013 Preakness trained by D. Wayne Lukas (Oxbow, Will Take Charge and Titletown Five).
70: Number of odd-on favorites to win the Preakness.
33: Number of horses who have one both the Kentucky Derby and the Preakness, the first two races in the Triple Crown (only 11 have won the title).
$1 million: The assessed value (done in 1983) of the Woodland Trophy, presented each year to the Preakness winner. No one takes the 29-pound trophy with them, however; winners receive a $30,000 replica instead.
6: The number of drops of Angostura Bitters that goes into a Black-Eyed Susan, the official Preakness cocktail.
18 inches by 90 inches: The size of the blanket, made of Black-Eyed Susan daisies, draped on the shoulders of the Preakness winner. The race occurs before the official race flower typicaly blooms, so the blanket's creators use black lacquer to improve its appearance.
121,309: The number of people who attended the 2012 Preakness, a record.
1 minute, 53 seconds: The record Preakness time, set by Secretariat in 1973.
6: Best Preakness finish by a female jockey (Patricia Cooksey on Tajawa in 1985).
1898: The last time an African-American jockey won the Preakness.
