More than 30,000 spectators are expected to visit this year's Lowther show ground in Cumbria over the weekend.
The show, which was cancelled in 2008 due to bad weather, was revived three years ago and now has over one hundred competitors in the carriage trials.
Organisers insist they are confident the event will still go ahead as planned despite predictions of heavy rain over the weekend.
