WILLIAMSBURG, Ohio — Saturday's Bill Brewer Honor Run at Williamsburg High School celebrates the life and legacy of Det. Bill Brewer.

"We just want to continue his memory, so nobody forgets the sacrifice that he made," Rachel Lefker, an event participant, said.

In February 2019, Brewer, a 20-year veteran of the Clermont County Sheriff’s Office, was killed in a 12-hour-long standoff with a suspect in an apartment complex in Pierce Township.

"Deputy Brewer gave his life attempting to help a person who was admittedly suicidal," Sheriff Steve Leahy said in a statement. “This will forever change the atmosphere of the Clermont County Sheriff’s Office.”

Now, people are coming together to remember Brewer with 5K and 10K runs, and to raise money for scholarships at his alma mater, Williamsburg High School.

Money raised from the 5K will go towards scholarships available to any senior at Willaimsburg High School, and the money from the 10K will go towards the Williamsburg High School football team. Brewer is an Athletic Hall of Fame Athlete for Williamsburg.

The bourbon will flow again, flowery hats and humans will return to the scene and 19 horses will run the most chaotic race of their lives. After being disrupted by a pandemic, the Kentucky Derby is back with many of its traditions intact.

America’s longest continuously held sporting event returns to its traditional spot on the calendar — the first Saturday in May. The 147th edition comes less than eight months after its run without spectators last September because of COVID-19, making it the shortest time between Derbies in history.

Here, we'll break down everything you need to know about the biggest event in Louisville:

The horses

Each year, 20 horses compete in the Kentucky Derby.

Essential Quality is the early 2-1 favorite on Saturday and has the bona fides. The striking gray colt was last year's 2-year-old champion. He comes in undefeated in five career starts. The last unbeaten colt to win the Derby was Justify in 2018, and he went on to sweep the Triple Crown.

Essential Quality's jockey, Luis Saez, is seeking his first Derby win after crossing the finish line first aboard Maximum Security in 2019 only to have his colt disqualified.

“Essential Quality is a deserving favorite,” trainer Todd Pletcher said, “but I think it's a wide-open race.”

Besides Essential Quality, the other undefeated horses in the field are 5-1 Rock Your World and 50-1 Helium, both 3-0. Rock Your World won his first two starts on turf before switching to dirt and winning the Santa Anita Derby.

Changes due to COVID-19

Attendance of about 45,000 is expected at the Derby, about 100,000 less than usual.

Churchill Downs limited seating to 40-50%, up to 60% in certain private areas that allow social distancing.

Churchill Downs officials anticipate about 50,000 people for Oaks and Derby.

Masks will be mandatory — which should come as no surprise with a statewide mandate still in place.

Churchill Downs says it has implemented a "Compliance Ambassador program" to drive awareness and adoption of public safety measures. Signage is placed throughout the facility, including the Infield, to remind guests to wear masks and practice social distancing.

In addition, food and drinks are all-inclusive to lessen long lines and separate payments for every transaction.

The fashion

Half the fun of the Derby is the fashion, of course! And with fans back in the stands, there is sure to be plenty of it.
