In June 2015 she said: "My favorite run today is 5,000 meters, but even I've never run a marathon or a half marathon. There are many people who want me to run a marathon next year to try to get to Rio. I don't know yet what my coach's plans are. He might surprise me and tell me we're going to run a marathon."[20]
On 29 May 2016, she finished the Ottawa Marathon in Canada, her first-ever marathon, with a time of 2:42:20 hours, and placed 7th.[5] On the basis of her time, Tiyouri qualified to represent Israel at the 2016 Summer Olympics.[21]

In October 2023, nine days after the 2023 Hamas-led attack on Israel, she ran in the Great 10K Berlin in Germany, and came in fifth with a time of 34:11 minutes.[26] She said: "The whole last week since the terrible Saturday has been really difficult emotionally, mentally, and physically in light of the horrors we experienced. It directly puts sports in perspective. Somewhere the thought of sports feels absurd when our country is at war, and when we are trying to digest the dimensions of hell. I was really confused Whether to compete or not, but after several conversations with family, very close friends. and the athletics association, I decided that I should compete because this is my way to represent the Israeli people, to be an ambassador and to contribute to the overall effort. To show everyone that we are strong and not going anywhere."[26]
