"You have to qualify . . . and then to come here is extremely expensive and a big commitment from my husband and all of us," she said.
"It's great. It makes you proud that you've actually qualified to get here. It's a big thing and you hope to do well."
In a normal day at Horse of the Year, Mrs Fitzsimons says, she feeds and waters the horses, mucks out and even goes for a ride all before she has breakfast.
Much of yesterday afternoon was spent preparing 9 year-old Katie for today's competition in the Welsh Section on Kokako Gold'n'Silk, known as "Sparky" in the paddock.
Mrs Fitzsimons was busy organising for today's competition and all the while preparing for her own showing events.
"Showing is a beauty contest. It's kind of like a Miss Universe contest. The horse has got to be beautiful, move nicely, be elegant, behave impeccably and catch your eye," she said.
While such high standards are a "big ask", she said her horses Taittinger and Totally Confidential had the potential to win ribbons.
"Oh yeah, I hope I get ribbons. That's why you come," she said.
And while Horse of the Year is the big event they travelled hundreds of kilometres for, the family still manage to get out and about in the Bay.
"We love Napier, Havelock North and getting up the peak," Mrs Fitzsimons said
