The endurance enthusiast said he trained for the record for six months.
"I have been dealing with the cold for several years," Romanovski told Guinness. "Half a year before the record, there was a decision made to try my strengths in this discipline. I did a few trainings, after which I decided that the record was within reach."
Romanovski previously broke the Guinness World Record for farthest distance cycled off-road in 12 hours when he took a 195.51-mile ride.
"I prepared for the ice record in a similar way to cycling," the athlete said. He said his preparations for both records involved training, rest and regeneration.
"Workouts are not difficult for me. My body is prepared for them. I like new challenges. I use the knowledge of paramedics, scientists and doctors," he said.
