Career
Berces is Hungary"s most successful ultra runner. During her career she set several world records, four of which still stand, and holds virtually all Hungarian records from 100 kilometers to 48 hours. In 2002, just two weeks after winning the European 24-hour Championship, she set a world record over 24 hours on the track as well as a 100-mile world record en route.
In 2004, Berces set a 24-hour world record on the treadmill and set a 100-mile world record as well en route.
Both of these records still stand and the strength of the 24 record is shown by the fact that at the time, it was better than the men"s world record.
