Though she hadn't finished running until midnight on Saturday, when she arrived in Flaxmere she was pumped to celebrate her achievement.
She said it had been great to have support the whole run, which continued over the finish line with Maori Party co-leader Te Ururoa Flavell running the last 20km with her.
A support crew accompanied her the whole run.
"To be in the middle of nowhere and hear people driving past and tooting to show their support, it was just great."
She had planned to run the entire 250km, but was not able to run a stretch as it was through a high crash risk area.
Aside from the second day, Mrs Olley's run had gone smoothly.
She was only able to run 40km on Thursday - two less than a marathon but 18km less than her daily goal.
She only had three hours sleep the night before, and her body had been recovering from the first day.
"I was gutted, I've got a high pain tolerance but that day was just a bad day," she said.
She said the last 6km were a struggle but, with her family singing and playing guitar beside her, she was able to finish.
Mrs Olley planned to do similar events biannually.
She said she would like to involve high schools, as that was the age she was when abused.
