Ms Wallace and her supporters are walking up and down Baldwin St, the world’s steepest street, 193 times to complete a lap for every 100km from Dunedin to Tralee (19,292km) to fundraise for her trip.
Ms Wallace was named this year’s New Zealand Rose of Tralee after winning the national title in April and is set to compete next month alongside women from around the world at the five-day Rose of Tralee festival in Tralee, County Kerry.
She said it would be really special for her to win the competition because she was someone who epitomised New Zealand and Irish culture.
"It just says how much the Irish community has reached out to other parts of the world.
"Being a third generation [Irish New Zealander] it would be really awesome to have that opportunity."
Friends, family and members of the public helped her tick off some of the laps.
About 70 laps into the day Ms Wallace said going back downhill was the hardest part.
"I definitely have noticed that I am not as fit as I thought I would be when I first decided to do this.
But when we’ve got this many people coming in and helping out it actually seems like quite a small number."
She is fundraising for flights, mandatory gifts and about 25 different outfits for while she is over there.
She said she did not have a specific target for the fundraising but any money left over would be donated to the Mental Health Foundation.
