Regine Berg (born 5 October 1958) is a Belgian former track and field sprinter who specialised in the 400 metres. Born in Ostend, she represented her country at the Summer Olympics in 1976 and 1980.[1] Berg won five national titles over 400 m and also two over 800 metres later in her career. She was a silver medallist at the 1985 IAAF World Indoor Games and participated three times at the European Athletics Indoor Championships.[2]
Berg's 400 m indoor best of 53.13 seconds was the Belgian record[3] for nearly 35 years until it was bested by Cynthia Bolingo's 52.70 at the 2019 Belgian Indoor Athletics Championships. She also shared in the 4 × 400 metres relay national record, set with Lea Alaerts, Anne Michel and Rosine Wallez at the 1980 Moscow Olympics[4] that stood for 38 years until it was bested by the Belgian Cheetahs. Her outdoor bests are 52.29 seconds for the 400 m and 2:00.43 minutes for the 800 m.[5]
