The club celebrated two anniversaries, with 100 years since racing started in the region and 60 years since the first Horsham night meeting.

The Noel Smith Memorial Horsham Invitation Drivers Championship was also decided on the day, with several of the top drivers from around the country competing.

Star driver Gavin Lang - who has become the first Australasian reinsman to notch 5000 career victories - was the winner of the championship, which was decided by placings across three races.

Lang took Mintropolitan to a win in the first of the drivers championship races and had good results in the other two to narrowly win.

Lang said he was honoured to win the series.

Ryan Hryhorec was second and defending champion Dexter Dunn third. Grant Dixon won the wooden spoon. Other drivers to take part were Daryl Douglas, Amanda Turnbull, Colin Brown, Glenn Sugars, Chris Alford and Garreth Rattray.

The club also used the occasion to launch a 72-page book detailing its history.

Minister for Sport and Recreation Hugh Delahunty launched the book.

Club official Tony Logan said the day was a great success.

"There was a lot of interest in the book and a lot of interest in the display," he said.

"People brought along some items that we had not seen before and we'll be doing some more recording and photography on that.

"The book was very well received as well and a lot of people came back for that."

The day also included the return of the Westside Horsham Sulky Challenge - a $2000 competition for local football and netball clubs which was won by Laharum.
