Glenorchy Races will celebrate 50 years since the first meeting tomorrow, and organisers say they will be keeping things simple to mark the occasion.
The event has been held on the first Saturday of every year since 1962, and one of the organisers, Bruce Douglas, said they would be doing nothing different to reel in the crowds.
"We are keeping it simple because it has always worked in the past and people have enjoyed that."
The event attracts more than 2000 punters every year and Mr Douglas said he did not expect too many more, although he hoped visitors "from the days of old" would show up for the milestone.
The weekend clashes with the National Rugby 7s tournament in Queenstown, but he said this would not have much of an effect on the numbers attending the races.
"The 7s don't really affect us because the main day for the 7s is the Sunday."
The Glenorchy Races are organised by the Lakeside Rugby Club and raise money for community projects.
There would be 10 horse races held throughout the day beginning from 11am.
In order; the Walk Trot and Gallop, Saddling Race, Trotting Cup, Relay Race, Ladies Gallop, the Double Banking Race, Galloping Cup, Stockman's Race, the Quarter Mile Sprint and Local gallop.
Tickets can be bought on entry for $10.
