The theme at Adrenaline on Friday, August 21 is Ultimate Challenges, and those challenges will be both on and off the racetrack

.

On track, five races are planned for U.S. horses vs Canadian horses along with five 'Battle of the Sexes' races. The unique race conditions should make for some great racing and loads of fan interest. To see the complete condition sheet, click here.

First-race post time for this special card is 7:00 p.m. The entry box closes on Tuesday, August 18 at 11:00 a.m.

Off track, the entertainment will be as exhilarating and competitive as the races themselves, as 15 bands will compete in the Ultimate Band Challenge, which will be taking place between the racing action and following the completion of the card.

And don’t forget Toonie night. K106.3 FM, Sarnia and Port Huron’s best rock radio station, is proud to sponsor Toonie night on both Thursday, August 20 and Friday, August 21 at Adrenaline.

The toonie admission will allow you to enjoy all of the music, food vendors featuring award winning 'ribbers,' entertainment, games, contests, and racing on the track.

Gates open at 5:00 p.m.
