Less than quarter second made all the difference for the top prize of $17,800 at Warren's Cotton Cup race on Sunday.

Over 500 people passed the gates at Warren Racecourse for one of the most well attended race meetings in the local club's recent history.

Around 15-20 jockeys vied for a prize pool of over $250,000 across eight races. 

Warren Jockey Club president Paul Smith said it was the biggest crowd in at least six years.

"We've got obviously COVID behind us and we've had a couple of really good seasons out in the farms," Mr Smith said.

"Having said that, we probably would have had a double the crowd, but all the boys are out harvesting.

"It's great for the community to come together for the day."

Six-year-old horse Ancient Egypt pulled ahead of Sea of Flames with a margin of 0.1 second in the 1600-metre headline race to claim first place. 

Ancient Egypt's Tamworth trainer Wayne Brown and jockey Michael Heagney joined the winners room along with trainers Clint Lundholm, Brett Robb, Wayne Collison, Mack Griffith and Kathryn Cahill.  

There were plenty of wins off the track for Warren locals, who had a clean sweep with the fashion on the field.

Esther Kelly won Best Dressed Lady, Will Nicholas Best Dressed Gent.

Best Dressed Couple went to Emma and Louis Welsh, and Loretta Nicholas took home Best Millinery.

Mr Smith said another off-track success was the around 18x10-metre ticketed marquee tent that housed 120 people.

"Even after cut off [for ticketing], we had a high level of demand," Mr Smith said.

"Certainly for next year we'll be looking for probably a marquee twice as big."
