Christchurch's iconic Trotting Cup Day will be the biggest since the earthquakes began, organisers say.
Addington Raceway's marketing manager Jed Moore says ticket sales have been up "all the way through", with pre-sales up 15 per cent.
"We're expecting a good walk-up crowd too."
Moore says the event has been marketed and promoted strongly and despite losing their stand last year, temporary infrastructure has been set up to cater for the masses.
Moore predicts it will be a "superb" day.
