Fastest Kentucky Derby Times: What History Tells Us

The Kentucky Derby (G1) adopted its current 1 1/4-mile distance in 1896. In the ensuing decades, the fastest and average winning times have decreased significantly.

The average winning time of the Kentucky Derby decreased from 2:10.31 in the late 1890s to a low of 2:01.64 in the 1960s. The fastest winning time likewise dropped sharply, from 2:07.75 in 1896 down to 1:59.40 in 1973.

However, the average winning time by decade has largely plateaued since the 1950s, varying by only 1.45 seconds from 2:01.64 to 2:03.09. Meanwhile, the fastest winning time has gone unbeaten for over half a century.

Slow times during the early years

The first 21 editions of the Kentucky Derby took place over 1 1/2 miles. The first edition over 1 1/4 miles saw Ben Brush clock 2:07.75 on a track labeled dusty. By the end of the decade, the average winning time for 1 1/4 miles was 2:10.31.

Note: All times recorded in quarters or fifths of seconds have been converted to their equivalents in hundredths.

The first decade of the 20th century produced slightly quicker times. While Stone Street ran the slowest 1 1/4-mile Derby of all (clocking 2:15.20 over a heavy track), Lieut. Gibson lowered the Derby record to 2:06.25, and the average winning time for the decade came in at 2:09.58.

Three records set in the 1910s

The caliber of Kentucky Derby winners rose sharply in the 1910s, with future Hall of Fame inductees Old Rosebud, Regret, Exterminator, and Sir Barton winning the Roses. Partly as a result, the average winning time dropped to 2:06.36.

The Derby speed record fell three times in the 1910s, with Meridian clocking 2:05.00, Donerail going in 2:04.80, and Old Rosebud reaching the wire in 2:03.40.

The 1920s yielded similar times. While no new records were set, Bubbling Over ran a 2:03.80 in 1926, and the average winning time came in at 2:06.70.

Triple Crown winners pick up the pace

The 1930s and 1940s saw seven horses sweep the elusive Triple Crown: Gallant Fox, Omaha, War Admiral, Whirlaway, Count Fleet, Assault, and Citation. This golden age of racing saw many top-notch horses win the Kentucky Derby, and the average winning time continued to drop.

During the 1930s, the average winning time fell to 2:04.54.

In the 1940s, the average winning time was similar: 2:04.90.

From 1930 through 1949, no Derby winner ran slower than 2:07.60, and two recorded record times: Twenty Grand clocked 2:01.80 in 1931, and Whirlaway hit the wire in 2:01.40 in 1941.

The 1950s set a new standard of excellence

In the 1940s, five Kentucky Derby winners completed the race in 2:05.00 or slower. In the 1950s, only one winner (Tim Tam, over a muddy track) ran as slow as 2:05.00, and nine of them won in 2:03.40 or faster.

No speed records were set during the 1950s, but generally fast times across the board lowered the average winning time to 2:02.54, breaking the previous standard set in the 1930s by two seconds.

Records fell in the 1960s and 1970s

After more than 20 years, Whirlaway’s Kentucky Derby record time fell in 1962, when Decidedly clocked 2:00.40—the first winning time under 2:01.00. Two years later, Northern Dancer lowered the mark to 2:00.00. Then in 1967, Proud Clarion won the Derby in 2:00.60.

This trio of sub-2:01 clockings helped lower the Derby’s average winning time for the 1960s to 2:01.64, which remains the fastest single-decade average in history.

The 1970s produced another milestone as legendary Triple Crown winner Secretariat became the first horse to break the 2:00 mark, setting a still-standing Derby record of 1:59.40.

But Secretariat was the only Derby winner to run under 2:01.20 in the 1970s, and the average winning time for the decade rose to 2:02.14.

Plateauing through the 1980s onward

In the 1980s, Spend a Buck won the Derby in 2:00.20, but the rest of the decade’s Derby winners ran no quicker than 2:02.00, producing an average winning time of 2:02.46.

The 1990s yielded a nearly identical average winning time of 2:02.47, with Grindstone (2:01.06) ranking as the fastest winner.

In the 2000s, Monarchos clocked the second-fastest Derby on record (1:59.97), helping lower the average winning time for the decade to 2:01.82.

But in the 2010s, five Derbys were contested over tracks labeled sloppy or wet fast, and the average winning time rose to 2:03.09, the slowest since the 1940s.

The 2020s are off to a better start, thanks in part to Authentic, who clocked 2:00.61 to win the 2020 Derby, which was delayed by four months due to COVID-19. Through 2025, the average winning time for the 2020s stands at 2:01.91.

Fast times continue in the present day

Overall, winning times in the Kentucky Derby haven’t changed much in the last 75 years, as evidenced by the minimal 1.45-second variance in average winning times by decade since the 1950s.

Average winning times in the Kentucky Derby, by decade

The Kentucky Derby produced the majority of its fastest winning times between 1962 and 1985, when five of the seven sub-2:01 clockings were recorded, including Secretariat’s still-standing record of 1:59.40.

However, nine of the 19 fastest Kentucky Derbys have been contested since 2000, ranging from Monarchos’ 1:59.97 to Mage’s 2:01.57, showing it’s still possible for Derby winners to record fast times.
