The field for the Kentucky Derby is limited each year to 20 horses, with two 'also eligibles' in case of a late withdrawal from the field. To determine eligibility, Churchill Downs developed the Road to the Kentucky Derby, which gives points to the top four finishers in specified races. The 2016 season consists of 34 races, 19 races for the Kentucky Derby Prep Season and 15 races for the Kentucky Derby Championship Season. Earnings in non-restricted stakes act as a tie breaker. Gun Runner finished first in the standings thanks to wins in the Risen Star Stakes and Louisiana Derby, then finished third in the Kentucky Derby. Nyquist, who finished second in the qualification standings, won the Derby.
