The Super Trifecta is one of the more exotic wagers at the track.
Gamblers have to hit the Trifecta race, correctly picking the first-, second- and third-place horses in the sixth race, he said.
Then, to win the big prize, the bettors have to pick the first, second, third and fourth finishers in the correct order in the seventh race, Bork said.
The last time the prize was won was on July 19, when the prize was $2,500, Bork said.
Since then, prize money was put into the pot after each race, raising the jackpot to the current record number, Bork said.
Collins said he nearly hit the prize about a month ago when the jackpot was at $32,000.
He hit the Trifecta on the number, and then correctly picked the top four horses in the next race. Unfortunately for him, he did not get the order they crossed the finish line correct.
"It's so hard to pick," Collins said.
If the correct combination is not hit Wednesday, track officials will award the prize money to the person, or people, who come closest, Bork said.
The track is also giving a voucher for a free wager to the first 1,000 people at the track, which opens at 10:30 a.m.
On recent Wednesdays, the track has been drawing about 1,500 people, Bork said. This is a slow time of year for the track, where business starts to pick up again in about March.
But with the large prize, Bork said he expects about 2,500 people to attend.
Chuck Leffew, 57, of Leesburg, Va., said he intends to be one of the first in line to get in today.
"It's a better chance than Lotto," Leffew said.
