Henrietta Knight opens the doors to the public at her West Lockinge Farm stables, near Wantage, on Sunday, September 25.
Knight, who famously trained Best Mate to win three Cheltenham Gold Cups from 2002-2004, will parade her string at 12noon, with the yard then open to 3.30pm.
Horses on show are set to include the classy Somersby and Calgary Bay, who ran in the John Smith’s Grand National last season where he fell at the fourth fence.
There will also be a dog agility display.
Entry is £10 per person, with children under 16 free.
Profits go to the Chiltern & Thames Air Ambulance.
