The judge said Emma Morrison (43) was an excellent witness "and told it as it was".
Emma Morrison (43), originally from Cork but living in the Liberties, Dublin, sued the Madigan Group Trading Co Unlimited, operators of the Horse Show House, where the accident happened during a work-organised barbeque in June 2017.
The court heard decking leading from the beer garden into the pub was very slippery and a number of others had slipped on it the evening Ms Morrison fell, coming down hard on her ankle.
Before the accident, Ms Morrison was a keen runner, putting in up to 7km three times a week. She had participated in a number of 10km runs.
Due to complications from her injury, that activity has been curtailed although she has got back to jogging, the court heard.
Madigans admitted liability and the value of the case was assessed by Mr Justice Michael Hanna at €100,000 for past and future damages, along with €5,000 in special damages.
The judge said Ms Morrison was an excellent witness "and told it as it was".
She suffered a "nasty fracture at a work do" and initially thought she had hurt her ankle but "not that much", he said. She got a taxi home and rested on the day afterwards.
However, by the second day it was not getting any better. She went to a clinic and "found out, no doubt to her horror, that she had fractured it and required a plaster of Paris", the judge said.
The plaster remained on for six weeks and she had to use crutches to get around.
It later transpired that the fracture did not knit back together again and this required surgery, where she had plates and screws inserted in her ankle, the judge said. She was a genuinely active person who loved running and walking her dog but when the metalwork in her ankle was removed, this itself brought further problems, he said.
Even though she got back to running, it became curtailed and she had ongoing problems and pain which she deals with by way of physiotherapy. She was left with an 8cm scar which he said was prominent and had caused a discoloration of the skin.
There will apparently be no long-term complications such as arthritis but she continues to experience activity-related discomfort and pain which interferes with "her great love" of running, he said.
She liked to dress smartly, including wearing high heels, which she could no longer do, he said.
The judge, who also remarked that he had apparently been "put on a Jimmy Choo hit list" over comments he made previously about women's love for high heels, said while this was still "something utterly foreign" to him, it was something women enjoyed.
Ms Morrison was entitled to be compensated for a serious injury, he said. While she can still carry on her profession, the overall impact of the injury will be "real and lifelong" and she will have to put up with ongoing pain and discomfort from running and also while walking her dog, he said.
He agreed to put a stay on the award of €105,000 in the event of an appeal if half of it was paid out.
